4:05 An open diff sends power 50/50 until one tire runs out of grip. Once either tire starts slipping effectively 100% of power is being sent to the tire with the least grip which provides very limited acceleration.
What you said makes sense about the car having the power to do straight line both tire burnouts but then only doing a one wheel peel on turns, I was told my challenger already had the lsd but that’s exactly what it does, straight line burnouts are both tires, but the slightest curve and it’s a 1 tire fire. Will definitely look into this mod
If you haven't stumbled upon this already, the 15' and up have a bastardized version of torque vectoring that applies the brake to even the grip on both wheels in certain conditions, making the open differential act as an LSD. This method is flawed and doesn't help a majority of the time, but definitely had me thinking my 2015 Chrysler 300 S 3.6 had an LSD
Thanks Man So Much , You Really Reassured me , I already have the gears and plan to get them installed in two weeks , this video was highly needed, thumbs up definitely deserved 💯👏🏽
@@freightrain808 Perfect timing on the question! I just did it about a week ago. It took me like 6 hours and that was with a lift (I have access to a lift I can use for free whenever I want luckily). Pretty much exactly like @DonnyR/T said in the video. Drop the exhaust from the mid pipes back, drop the old differential, then reinstall everything in reverse. You're going to have to man-handle stuff, just try to be careful while you're doing it if that makes sense haha. No problems so far, still working on getting in those 500 miles before I push it though. One last thing, just make sure you have the 5.7 in your 300s or this won't work for you, it's a different differential.
@@idunno3639 hey, so i have a 2015 pursuit charger. Its 5.7L awd. Can i put an lsd from a hellcat.(its 2.62 gears and I believe same as my open differential) i am only confused because my car has 5 spd nag1 tranny. Not the 8spd newer one. So does that make any difference?
@@harsimransingh7036 I'd have to do some research for sure but I'm pretty sure not many things on the AWD models swap over when it comes to the drive train. I've seen a bunch of videos where the comments say if it's an AWD they take different than the normal parts on the RWD models
Quick question. Have you seen changes in your 0 to 60? What times are you getting? Reinstall advice. After slipping in the axles, bolt on the drive shaft before lifting all the way up in place. When you’re one person slid under the car, this helps with getting the holes lined up.
Hey! I've really gotta upgrade my tires before I do some real testing. Other people that have done the install say that yes they have seen a better time. Also, thank you for the advice! Hopefully it helps others with their installs
Anytime you open the inspection cover and screw with the gears by doing whatever when pulling them out you want a break in period so the gears set properly if not already and so if there is a whining or problem with the diff you can fix it before causing to much damage.
Quick Update: so I still haven’t put the 3.09 lsd in yet but got a tune yesterday on my stock 3.07 gears.. im now doing 2 wheel peels with no problem even with traction control on. Wasn’t doing that before.. I’m still going to swap 3.09s soon
Just did my 3.09 swap, and everything drives fine. But now I hear a small squeak when I put the car into drive. Sounds like it’s coming from the back side
As far as you having a little problem getting the half shafts in...Jack up the rear when your on the lift and turn the wheel till it slips in...Super easy...Took 1.5 hours literally to change

Not a bad vid for just a guy morning his car. You really should have pulled the wheels and pulled the axels right. It would have saved you time and money. Also, an open dif delivers equal torque to both wheels, not equal power. There is a difference. If 1 looses traction then it takes very little or no torque to turn it so therefore delivers very little or no torque to the other wheel causing it not to spin. This is also cause for leaving 2 marks on takeoff. If both wheels have equal traction both will spin equally. I hope you enjoy your new gears man. I'll try to watch some more of your stuff
I appreciate the feedback lol.... if you want to split hairs about the units of torque vs power we can. I’ve made videos describing the differences between them and how they’re determined from dynos. I have an engineering background so I wouldn’t necessarily say I’m “just a guy nodding his car,” but I appreciate the double edged sword I guess...
@@DonnySRT there is a difference between torque and power and in a dif it does make the difference. A racing spool delivers equal power for example. I wasn't hating on you. It was a good vid and like I said before I hope you enjoy your upgrade
🔥🔥🏁👍 you really smoked RTdrop my 2006 SRT has open differential 306 but it’s still pretty fast my 392 really hooks up what year is that other charge the white one? Does it have insane wheel gap
Hey! Great video! I have 22 charger rt daytona and i’m planning on switching my differential! Do we need to change the gear ratio or install any tune or anything?
Question did you get a check engine light when you put the 3.09 without tune I get 2 codes p215coo and p1d600 wondering if it’s my sensor or just me not having trans tuned yet?
Hey bro! Do you mind telling how you were able to torque the 8 bolts down on the drive shaft? Were you able to torque them down to spec by hand or??? Thank you 😊
Yes it can the challenger and charger shares the same platform as the Chrysler 300, but there are some parts that stay exclusively to them. The rt rear axel differential is compatible with the 392 and the models above it. You need that distribute the high power that your hemi engine produces to the rear wheels along with a compatible clutch or something that holds the power of your engine.
I looked up the limited slip differential thru your link for my car i have the same year charger rt but it says that it will fit the 230mm cv axle will it still fit the 220mm
I texted Jay greene about this and he said I would have to change the ratio in the body control module. I have a 2019 charger rt. Did you ? Have you heard of this?
I don't think I would have spent all that for such a small improvement in ratio, around 340 would have been a lot better and you have the overdrive to make good MPG and top end. I have a 390 in my Scat Pack Challenger. BTW Open dif on a lift will turn in opposite directions when you turn one by hand and LSD will turn the same direction.
Hey whats up man, I did the 3.09 swap and everything went well, i had trouble getting the right axle to go into the diff, but i got it to go afterall, i didnt have any problems till now, i went to the drag strip and did 2 passes, after the second pass i checked the diff and it had oil all over the right side, looks like its coming from where the axle seats with the diff. I took a pray bar and wiggled it between them and I can push the axle out a little bit. It only happens on the right side, left side seated pretty well, no leaks, play, or anything. Hope you can help me man, I would really appreciate your help. Thanks!
@@DonnySRT everything looks to be okay, i cleand it and left it seat overnight, this moring i checked it and it looked clean, no more oil, and i did drove it a bit before checking it. When i filled the diff with oil, i had the rear of the car lifted about 1 and a half feet on the air, idk if i might have overfilled it with fluid(do you think that has soemthing to do with it?). Im gonna check the oil level, i just have to unbolt the fill bolt when the car its leveled and let the oil drain untill it stops right? Thats how ill know it has the correc amount? Thanks for the replay!
Hey what's good Im hoping I can do this mod on my Chrysler 300s AWD can I just swap that rear end for the 3.09 anyone know Thanks nice work donnyrt car looks great👍👍
Considering the difference in price between a pedal commander and swapping out the diffs. Do you think just getting a pedal commander will help out with getting off the line more even if it’s not as much as switching diffs? Thx bro!
No. People get hyper-fixated on the pedal commander when it doesn't actually do anything besides adjust throttle sensitivity. This is a mechanically different part
Very informative.. quick question.. I found one used but it says hellcat 3.09 LSD…. Is there a difference between all of the 3.09 diffs or are they all just plug n play?
They are plug and play for the 5.7 6.4 etc. The v6 is plugged and play but you'll need additional parts like the 5.7 axles or 392 axles then the differential of you choice.
@@DonnySRT cool, i have the pursuit pacakge so its a base model sxt and they put the 5.7 hemi and 5 speed trans and driveshaft, everything else is stock sxt pretty cool
Random shot in the dark, anyone happen to know the spline count on the cv axles where they go into the diff? Is it 32, 37 or 38; I’ve seen all 3 in my Google searches.
The RT rear axel differential is compatible to all the models that is above it or under. You need to distribute the massive power to the wheels depends on the engine you have
Any of the challenger/charger Diffs from 15+ V8s will fit other 15+ V8s....the key here isn't just the 3.09 being a tiny bit better off the line (compared to the 2.62 Open) but the fact that its an LSD vs. an Open diff...
Hey. I’m not entirely sure about the warranty thing mostly because dealers are always wishy washy about it (I can’t stand them lol). Have you asked them if they can install it? Mopar lists this as a replacement part for our cars online
@@DonnySRT yes I've asked and they want 1k to install it. But I tried to call mopar warranty and it said 24/7 support but told me to call back in business hours lmao.
Lmaoo about them being closed lol. Yea it says it’s a replacement part for our cars on the website. Also 1k is an outrageous amount. What is your opinion on that?

Considering the difference in price between a pedal commander and swapping out the diffs. Do you think just getting a pedal commander will help out with getting off the line more even if it’s not as much as switching diffs? Thx bro!
No. People get hyper-fixated on the pedal commander when it doesn't actually do anything besides adjust throttle sensitivity. This is a mechanically different part
might do this on my 300S
I love a modded 300 🤟🏼🤟🏼
I just did it, Ill let you know how it goes
@@mattieice4689 damn i don’t even remember commenting this… i ended up buying a srt 392 Lol
@@srtphantom7029 all good
Will still provide some perspective
Very informative.. quick question.. I found one used but it says hellcat 3.09 LSD…. Is there a difference between all of the 3.09 diffs or are they all just plug n play?
They are plug and play for the 5.7 6.4 etc. The v6 is plugged and play but you'll need additional parts like the 5.7 axles or 392 axles then the differential of you choice.
thanks for the vid brotha, does the r/t already have the right driveshaft diameter?
I mentioned that it bolts directly in. Pretty straightforward swap
@@DonnySRT cool, i have the pursuit pacakge so its a base model sxt and they put the 5.7 hemi and 5 speed trans and driveshaft, everything else is stock sxt pretty cool
Actually, now that you mention, I am not sure if this diff will bolt up to the 5 speed trans. Something to keep in mind
@@DonnySRT ok ill probly have to match it to the same year
Did you do this on jack stands with the tires still on?
Yes to jack stands. Removing the tire doesn’t do anything unless you remove the hub bolt too
I feel like I'm watching the preequal to engineering explained's channel, the college years. 😁
LMAO! Ill take that as a compliment
@DonnyR/T I have a 17 Dodge Charger Daytona 5.7L will need a tune for the 3.09 lsd differential
220mm is the diff gear size not axel size right ?
So what oil do I have to use now with the 3.09
Random shot in the dark, anyone happen to know the spline count on the cv axles where they go into the diff? Is it 32, 37 or 38; I’ve seen all 3 in my Google searches.
Hello will this work on a 2018 Dodge charger R/T that is stock?
yes
I have 18 rt do I need 230 mm axels or 220?
Hey where did you get the new boot? Mine ripped
im late to this video , but no tune was needed ?
I have a 2021 Chrysler 300 5.7. Do you think I am able to get this diff on amd the axels fitting in with no issues? Like a plug and play?
did you get a answer?
@richardbehrie sold the car no long ago from that comment. Never really found out of it was possible.
Will this fit my 2017 Dodge Charger RT
how many quarts of differential oil u needed?
Direct swap for 2016 charger Rt ? Been seeing every forum and I’ve found mixed answers!
The RT rear axel differential is compatible to all the models that is above it or under. You need to distribute the massive power to the wheels depends on the engine you have
did you need to tune your RT after install?
Nope. But a tune never hurts
@@DonnySRT So the MPH is still accurate?
I believe so. Everything seems to point that speed is measured from a wheel rotation sensor and not from driveshaft rotations
@@DonnySRT awesome - thanks man. I really appreciate the help.
u can change the gear ratio if u have a diablo sport, there’s an option under transmission i believe
What to do when wheel speed mismatch after swapping rear end I did 306 gears in my RT and now car in limp mode won’t go out of 3rd gear
You must reset TCU and input your new gear ratio with Hp tuners, Diablo or anther programmer or tuners
I have a 2018 charger rt plus super track pack can I do this ?
Will this fit on 15 sxt? Im asking cuz i wanna do 392 swap in the future
There are more parts required for this. It isn't as easy as it was on the r/t with 220mm axles
Putting 305 on the back helps . Those 245 not good for all that power & wait u will hook better
Did u tune it
Dumb question but want to make sure I have a 2020 charger rt. With the 220mm 2.62 ratio this I is a straight bolt on even though it's a230mm
it fits
You don't need a tune? I think 11-14 only maybe then?
Do you know if it would fit a 2013 charger rt ?
This specific one won’t but there are options for those model years
Do 2011-2014 chargers require a tune?
Does the car need a tune after doing this mod
Does the 3.09 fit in a 2013 rt?
Just did the 3.73 getrag swap into my 300c and am hitting the redline nasty on wot I set everything in my tuner as it should be set but no cigar
Hey what year is your 300? And is it awd?
@@harsimransingh7036 06 not a awd
Would this 309 work on a 06 Chrysler 300?
How did you know the proper differential for your car?
Any of the challenger/charger Diffs from 15+ V8s will fit other 15+ V8s....the key here isn't just the 3.09 being a tiny bit better off the line (compared to the 2.62 Open) but the fact that its an LSD vs. an Open diff...
@@robcolletti i found one that says hellcat 3.09 lsd will that fit my 2015 rt? Thankz bro
@@raulamescua9487 should fit yes
Damn was hoping you'd answer the warranty one
Hey. I’m not entirely sure about the warranty thing mostly because dealers are always wishy washy about it (I can’t stand them lol). Have you asked them if they can install it? Mopar lists this as a replacement part for our cars online
@@DonnySRT yes I've asked and they want 1k to install it. But I tried to call mopar warranty and it said 24/7 support but told me to call back in business hours lmao.
Lmaoo about them being closed lol. Yea it says it’s a replacement part for our cars on the website. Also 1k is an outrageous amount. What is your opinion on that?

@@DonnySRT I decided to hold off till I can get it confirmed from mopar but no way in hell will I drop 1k on 12 bolts and some time. Lmao
Can you put the 3.09 lsd on a 2008 R/T Charger?
This specific differential will not bolt right up in the pre-15 cars
@@DonnySRT What’s an differential you’ll recommend then? I have an 2007 but want similar gearing
Did you get a check engine light?
No
Is it the same on a challenger?
I believe so
Can you put a 3.09 diff on that older charger ?
My 2013 charger is also an rt so just curious if the 3.09 works on my car
No, but other differentials can work for it
@@DonnySRT but are there any other limited slip differential‘s that would fit on a 215 mm axle
