Great video I have and 03 g with a six speed. Open diff😭. It’s my daily driver. Already have STILLEN cai Z tube and plenum spacer. Need to swap the diff and maybe an HR y pipe. Then tune.👌🏻 Great information here thank you.
If im not mistaken the reason people want to buy the 370z diff is because of the gear ratio as well as a VLSD? I could be wrong but thats what im looking for, a diff with a better gear ratio that i can easily drift and do burnouts if needed.
I would like to update everyone I’m doing this project now good news! Flanges are interchangeable. Pinion gear on an 08 g35x has 31 teeth same as the Nissan 4 hole flange, will post pictures below
I have a 06 350 base, open diff. I came across a 05 vsld auto. I would like to swap if possible, but now having second thoughts because of that gearing ratio you were talking about. Because I dont know, I am curious if I can have any of the gearing parts swapped into the vsld to keep the better ratio, or dose it not work like that. What do you think??
I raced a 350z DE M/T vs my G35 sedan A/T at the 1/4 drag strip and 1/4 times where slightly different him being slightly faster time wise but I took his ass at the finish line....
Good luck! Make sure the vLSD has low miles or it won't be good anymore. They stop doing much after about 100,000 miles. They can be rebuilt, but the price for an aftermarket diff at that point is a better buy.

Thanks, really do appreciate the advice and vids especially living out in the Pacific its crucial I get my info down patttt👍🏝🇬🇺
@@meggetpangie6199 you need a 3.69 diff with (likely) a 3 bolt pinion flange. Check your flange first to ensure you get the correct bolt pattern. Don't waste your time with the 3.53
This has made me seriously consider getting a 3.69 diff for my 2004 350Z, which is primarily a track-dedicated car and which I am slowly building to be a better track car. In the 24 hrs since first watching this video and searching online for one I keep finding tons of (cheaper) diffs for AT, then also many designated as "non-locking" for manual transmission (which is what I have). I have a basic knowledge when it comes to the difference between locking, open, and limited slip differentials, however, what is a non-locking one? Opposite of locking, thus an open diff? I want the VLSD, but all the diffs so far that I have found with mileage under 50k are $400-$600 range, and then not even sure if they are VLSD's. Thanks for the help.
Locking and vLSD are the same for this car. You'll want one with less than 75K on it if you want the vLSD to work, but really, getting an open 3.69 is the best deal for a track build because you should just buy an aftermarket diff. They aren't cheap, but they're much better than the vLSD, especially after they have a lot of miles on them. I'll probably get the Tomei diff as it's reasonably priced.
Would you have preferred 3.92 if the option had become available to you? And would 3.92 be too low a gear ratio with a 6600rpm (or is it 6700?) redline? In the future I plan to change out cams and increase redline, but for the time being my DE engine's redline is stock, so I'm trying to decide between 3.69 and 3.92. Thanks as always.
@@350Z247 Alright I pulled the trigger today on a 3.69 VLSD, but it wasn't anywhere near as cheap as the one you purchased, but based on what was available out there a "good" price. Did you drain the diff oil before lowering it, and did you add oil to the new one before or after raising it into position?
I know this is a little old. I have to replace the diff on my 2007 350 roadster manual. I watched this video and the second one. Can you just tell me exactly what i need? I the 3.9 diff that your list has on G37 convertible, i know it will have the round connector i got that. About the diff bushings, how many is there? Can you give me a link to buy? Will i need to get different axles? Which should i get,? Please advise
Correct me if I'm wrong but what about LSD? How can I be sure I don't swap my '04 MT 350z lsd diff 3.5 ratio to some 3,7 open diff? I mean how can we avoid that? I got 2 diffs to buy. Both are from G37
The only way you can tell if you aren't right in front of it is based solely on the people selling it. If it's an LSD, they'll advertise that. If you receive it and they lied, you should be able to return it at their expense if it's eBay. If you're at a junkyard, turn the pinion and both axle stubs should turn the same direction.
I have a sports car and I go from a 35mm to a 30mm and can’t really tell a difference by sight but by how much easier on my clutch, top speed and acceleration that’s the difference I notice.
Hey bro great vid, so for a 2013 g37 sedan automatic I have a 3.357 , so I should be looking for a 08 07 differential which has a 3.7? Sorry I wasn’t sure if I understood the video correctly
First, check to see if the pinion flange on your car has three bolts or four. It's probably a three bolt flange. What you'll have to do is swap the flange on the diff you buy with the one you currently have. You should be shopping for a diff from a manual transmission car. There aren't any differentials with the three bolt flange and the 3.69 gears. Swapping the flanges isn't very hard and a shop shouldn't charge you much to do it if you bring in both differentials to them.
Im not sure what I should do.. I have a 6sp manual FBO Tuned G35.. I usually do 20-120 or 40-140 runs and maybe a dig once in a while in mexico lol.. u think it would make me faster and not hurt my topend if i switch from the 3.5 diff to the 3.7 and will it effect dyno numbers? It will prob get me a better hit from the roll im assuming but I just worried about the topend mainly, I am upgrading to the 370/g37 axles and bearings too thats really why I am suggesting the 3.7 diff.. a DE Non-RevUp but made decent power lol
Great vid. I got a carrier assembly from a 2008 g37 3.69 and I can't get the stub axles to pop in from my '03 g35. Did I get the wrong diff? The stubs look too short I think.
@@350Z247 i discovered that my open diff stubs are the wrong part (length width) and that I need stubs from a vlsd, any 03+. The part are Nissan 38220-AR010 and AR011. The open ones I got are AR000. Need to find me a junker who doesn't pilfer the stubs!
@@350Z247 I wanted to comment on this - the ABS ring count is difference on stub axles from Z33 to Z34. Since you didn’t swap yours, have your noticed any issues with ABS?
Everything should swap over smoothly. Just check under your car to see if the pinion flange is three pointed or circular with four bolts. Everything else is the same between all Gs and Zs.
Are the inner stubs interchangeable? threaded vs open hole? If i get one that is threaded, can i switch it to ones that open hole and it will work inside the diff?
So I have a 2003 basic 350Z looking to upgrade the differential what would you recommend then the G35S... And are you saying that's the 3.9 gear ratio what should I look up for used I think I kind of understand but I hope you see my comment and respond
Not unless you plan to upgrade to an aftermarket differential. The non-locking diffs are basically worthless. 3.7 gears are the most common and thus reasonably priced and easy enough to find. Good luck finding a 3.9 geared differential for less than $800-$1000. Watch the video through again, and it will guide you to the right differential.
So long as it's a 4 bolt from the output of the driveshaft to the diff, it'll bolt up. I have a 04 350z Touring and found a g35 sport sedan with that exact gearing (believe its auto with 4 bolts) and wondered if it will bolt up.
All Z/G differentials are exactly the same minus gear ratio, open vs vLSD, and input flange. The first two are a matter of choice. Just peak under your car to check the flange and match the shapes.
No, the rings are after the differential gear's effect on the car's speed; so, the car doesn't even know anything has changed. The sensor rings have the same number of teeth as before.
It depends om your budget and goals. It will provide better acceleration in each gear, but it may require an additional shift before crossing the 1/4 mile mark and your gas mileage will be slightly worse. The main disadvantage of the 3.9 is they are way more expensive as they are far more rare.
Bolted right in! Yes, raising the rev limit to 7,200 will allow you to use the gears more effectively assuming you have other breather mods. If the engine is completely stock, it won't like the high RPMs because the restrictions in the stock intake and exhaust will limit airflow up there. I would at minimum have a plenum spacer, K&N panel filter, and a Y pipe. High flow cars or test pipes would be a good add too before raising the rev limit.
Awesome. I'm going to go junkyard hunting this weekend then. I have front and rear diff bushings I wanted to install and a new bottle of fluid so I might as well!
@@350Z247 Alright after hours of searching I think I sourced one locally for ~$200. It is a 2011-2013 Infiniti G37 MT Locking RWD 3.692 carrier assembly. The parts store said the earlier models had a different part number and wanted ~$400 for it. Judging by the chart it looks like it should be fine but I'm wondering why the older one is so much more expensive. Low mileage perhaps?
@@michaelt779 it just varies. People basically charge whatever they want for these. The only difference there might be is some of the diffs use nuts and bolts while some are tapped for the bolts.
Do I need to find a manual diff for my manual 05 350Z or can it be an auto 3.7 locking? I see that I can change the flange out but what diffs are compatible?
I tried swapping the input flange on the three bolt diff with my four bolt flange, but I couldn't get the preload right. I'd recommend getting one that matches your car. You have a 4 bolt circular flange.
@@350Z247 what do you mean when you're talking about the "preload". I found an AT locking 3.7 for too good of a price and have seen that people just changed the flange to make it work but the "preload" comment is the only thing holding me back atm. I know that you have to trim some of the pinion on top of changing the flange
@@nene6569 clearances on differentials are vital; if you don't know what preload is, you probably need to outsource the work. The amount of compression on the crush washer needs to cause a certain mount of drag on the pinion. If the tolerances are too lose or too tight, the diff will be noisy and possible cause damage. I would recommend waiting for a diff with the correct flange as you'll be investing in a fancy torque wrench or paying someone else to swap it
@@NSWvet83 unless you have the skill and equipment to properly set gear lash, tack on another few hundred bucks to get the new gears installed. I'd recommend waiting for a good deal. Took me 3 months before I found mine.
I have a 2006 350z DE 5at automatic. So would this be a 100% remove and replace? Or would other parts be need to be replaced for compatibility? Also would my car have 3 bolts or 4 on the pinon flange, and if so what cars 3.7gear would I need to be compatible with my number of bolts on the pinon?
You're going to have to crawl under there and look. You might be three bolt. If you're a three bolt, you have very limited options of the 08 G coupe and 07-08 G sedan automatic models with the locking differential. it will be a very long (like 8-12 weeks) search.
You should have the 4 bolt circular flange like I did which will accept any manual transmission diff. The later year automatics switched to a 3 bolt triangular flange. You can get a 3.5, 3.7, or 3.9.
I couldn't find a diff from a 07-08 G35S which is your best option. You can look on online junkyards or wait. This one from a G37 is a great deal; you'll just need to swap the pinion flanges to keep your 4 bolt pattern. www.ebay.com/itm/2008-2015-INFINITI-G37-Q60-COUPE-OEM-AUTO-REAR-DIFFERENTIAL-3-69-LIMITED-SLIP/223479000486?fits=Model%3AG37&hash=item340862eda6:g:vcEAAOSwQd5cr5e~:sc:FedExHomeDelivery!29414!US!-1
@@QuikModsOBS too many variables for there to be a single right answer. Stock redline DE, I'd say 3.9 is as high as I would ever go. 7,200 to 7,800 would be OK for the 4.08. I wouldn't do 4.36 unless your engine is fully built and revving past 8,000. The gearing just becomes so short and almost unusable. Regardless, I don't know of they're worth the price for a non race build, especially if you aren't installing it yourself.
@@QuikModsOBS in that case I would go 4.08 when you install an aftermarket LSD. The 3.9 is more expensive and not worth it to me. As you build the engine more, you can raise the rev limit to 7,200-7,500 to counter the 4.08 shortening the gears. The 3.7 is a good budget upgrade in the meantime.
I found one once listed as 3.9 on eBay, but it was like $900. They're obviously super rare; so, it likely won't be am issue. The 370Z Nismo diff is much more common.

@@350Z247 I see. I found one for sale from a wrecked 6 speed g37 and wants to sell for 200 but I was just iffy on how it would fit.
Hey bro, what u recommend the 3.9 over the 3.69 for daily and drag racing
It depends om your budget and goals. It will provide better acceleration in each gear, but it may require an additional shift before crossing the 1/4 mile mark and your gas mileage will be slightly worse. The main disadvantage of the 3.9 is they are way more expensive as they are far more rare.
@@350Z247 thanks u bro,
You didn't need any additional parts? I have the VQ35DE, would increasing the rev limit with a tune in conjunction with this be a good idea?
Bolted right in! Yes, raising the rev limit to 7,200 will allow you to use the gears more effectively assuming you have other breather mods. If the engine is completely stock, it won't like the high RPMs because the restrictions in the stock intake and exhaust will limit airflow up there. I would at minimum have a plenum spacer, K&N panel filter, and a Y pipe. High flow cars or test pipes would be a good add too before raising the rev limit.
Awesome. I'm going to go junkyard hunting this weekend then. I have front and rear diff bushings I wanted to install and a new bottle of fluid so I might as well!
@@michaelt779 good luck man!
@@350Z247 Alright after hours of searching I think I sourced one locally for ~$200. It is a 2011-2013 Infiniti G37 MT Locking RWD 3.692 carrier assembly. The parts store said the earlier models had a different part number and wanted ~$400 for it. Judging by the chart it looks like it should be fine but I'm wondering why the older one is so much more expensive. Low mileage perhaps?
@@michaelt779 it just varies. People basically charge whatever they want for these. The only difference there might be is some of the diffs use nuts and bolts while some are tapped for the bolts.
Do I need to find a manual diff for my manual 05 350Z or can it be an auto 3.7 locking? I see that I can change the flange out but what diffs are compatible?
I tried swapping the input flange on the three bolt diff with my four bolt flange, but I couldn't get the preload right. I'd recommend getting one that matches your car. You have a 4 bolt circular flange.
@@350Z247 Awesome. Thanks for the quick response! I'd hate to do all of this hunting and find one that doesn't fit.
@@travismills4499 no problem man. It took me like three months before I found one that I liked for the price.
@@350Z247 what do you mean when you're talking about the "preload". I found an AT locking 3.7 for too good of a price and have seen that people just changed the flange to make it work but the "preload" comment is the only thing holding me back atm. I know that you have to trim some of the pinion on top of changing the flange
@@nene6569 clearances on differentials are vital; if you don't know what preload is, you probably need to outsource the work. The amount of compression on the crush washer needs to cause a certain mount of drag on the pinion. If the tolerances are too lose or too tight, the diff will be noisy and possible cause damage. I would recommend waiting for a diff with the correct flange as you'll be investing in a fancy torque wrench or paying someone else to swap it
Why does this say $300 when I can't find upgraded gears for less than a grand for my HR?
You clearly didn't watch the video. Try again.
I was looking for a link and didn't have the sound on, while being forced to watch the wife's Netflix option lol
@@NSWvet83 it's a used pumpkin from eBay or a junkyard.
@@350Z247 been looking for one for awhile. I'll probably just get the ring and pinion for $600 from Z1
@@NSWvet83 unless you have the skill and equipment to properly set gear lash, tack on another few hundred bucks to get the new gears installed. I'd recommend waiting for a good deal. Took me 3 months before I found mine.
I have a 2006 350z DE 5at automatic. So would this be a 100% remove and replace? Or would other parts be need to be replaced for compatibility? Also would my car have 3 bolts or 4 on the pinon flange, and if so what cars 3.7gear would I need to be compatible with my number of bolts on the pinon?
You're going to have to crawl under there and look. You might be three bolt. If you're a three bolt, you have very limited options of the 08 G coupe and 07-08 G sedan automatic models with the locking differential. it will be a very long (like 8-12 weeks) search.
350Z247 it looks like I have 4 bolt. So what would my options be? And also would a manual pumpkin swap into my automatic?
@@taylorfreudenthaler4409 Four bolt flange means any of the circled manual diffs will work on that list in the video.
350Z247 thanks so much for all the helpful information! Just earned a sub 👍
@@taylorfreudenthaler4409 glad I could help. Good luck!
So I can swap my 3.3 to a 3.5 without any issue? I have a 2003. I can use any year diff?
You should have the 4 bolt circular flange like I did which will accept any manual transmission diff. The later year automatics switched to a 3 bolt triangular flange. You can get a 3.5, 3.7, or 3.9.
I’ve got a 2014 370z, auto. So am I able looking for a 2015 auto?
You need an auto diff from a Nismo 2015 or newer
@@350Z247 I’m glad you understood what I was saying, I think I had a small stroke during that last part lol. Anyway, awesome thank you.
How much would I expect to improve 0-60 going from 3.538 to 3.692 gears?
A few tenths. It's not night and day, but it's more than a few bolt on mods will get you.
@@350Z247 I been thinking the 4.09 gears are a better bet. Only issue is I kinda chops the top speed.
@@fatjaysgarage you'll never use that top speed, but you will use that acceleration
The all wheel differential includes the limited slip correct?
If you watch part 2, I cover it well there.
Do u recommend 3.69 Gears for a 03 g35 NA??
Yeah, I think it would work great. Raising the redline with UpRev would pair well with the diff.
Can u post a link to one that’s on eBay rite now I wana get one for my 03 g35 just don’t wana get the wrong one I have 4 bolt flange
I couldn't find a diff from a 07-08 G35S which is your best option. You can look on online junkyards or wait. This one from a G37 is a great deal; you'll just need to swap the pinion flanges to keep your 4 bolt pattern. www.ebay.com/itm/2008-2015-INFINITI-G37-Q60-COUPE-OEM-AUTO-REAR-DIFFERENTIAL-3-69-LIMITED-SLIP/223479000486?fits=Model%3AG37&hash=item340862eda6:g:vcEAAOSwQd5cr5e~:sc:FedExHomeDelivery!29414!US!-1
What year and car differential would work best on my 03 auto DE?
Any manual car on the provided chart.
I got a 03 open diff.which one can I use?
Please refer to the chart in the video. Any differential from a manual car on that chart will do.
Found a 2015 nismo tech lsd diff for 600$:) now I can drift
Nice find! I would say that's worth it for sure!
Can I put a auto 3.69 gear in a Manuel car ?
Part 2 should answer any additional questions th-cam.com/video/pZ5EDq7QEEE/w-d-xo.html
What about an FX or the Qs? Do they use the same diff?
I don't know; you'll have to take a look under your car and compare.
@@350Z247 Sorry one more question. Do you know if an AWD g35 sedan diff would be the same as a RWD?
@@saidseven yes, but they're all going to be open riffs. No LSD for the AWD cars. They're good though if you're getting an aftermarket LSD anyway.
@@350Z247 I have a 03 350 and I found one online for cheap. Its off an 08 g35 AWD sedan (3.7) just wanted to make sure it would work.
@@saidseven it should but you'll need an LSD to get full effect of the shorter gears
Can u put the Manual one in the auto de
If the pinion flanges match, you could have a circular 4 bolt flange or a triangular 3 bolt flange. You'll have to check under your car to know.
What about 4.08 or 4.36
Those were never offered in a factory diff.
@@350Z247 have an opinion on doing 4.08 (4.36 wouldn't bother me either) yourself or just buying 3.9 rear straight up?
@@QuikModsOBS too many variables for there to be a single right answer. Stock redline DE, I'd say 3.9 is as high as I would ever go. 7,200 to 7,800 would be OK for the 4.08. I wouldn't do 4.36 unless your engine is fully built and revving past 8,000. The gearing just becomes so short and almost unusable. Regardless, I don't know of they're worth the price for a non race build, especially if you aren't installing it yourself.
@@350Z247mine is 05 rev up sedan 6mt, I definitely want to get into autoX then into track building.
@@QuikModsOBS in that case I would go 4.08 when you install an aftermarket LSD. The 3.9 is more expensive and not worth it to me. As you build the engine more, you can raise the rev limit to 7,200-7,500 to counter the 4.08 shortening the gears. The 3.7 is a good budget upgrade in the meantime.
From what I’ve seen the g37 convertibles are wrong the autos are 3.3 and the manuals are 3.6 from what I’ve heard on the internet
I found one once listed as 3.9 on eBay, but it was like $900. They're obviously super rare; so, it likely won't be am issue. The 370Z Nismo diff is much more common.
350Z247 the nismo ones are ridiculously expensive too
@@uhZeny yeah, that's why I just went with a 3.69
The car isn't going anywhere with open diff or broken vlsd. WASTE OF MONEY
Please avoid comments that aren't helpful. You obviously don't understand, but I would be happy to answer any questions.
Would the G37 differential work well on a 03 350z DE manual
It just depends on the pinion flange; yours is likely a circle. If you get a manual G37 differential, it will work, but those are pretty rare.
Sounds good thanks 👌🏼
