Hi Mike. I have been pondering the PSC Big Bore XD upgrade and finding your video was very helpful. Thank you once again for sharing your knowledge!
You’re welcome and thanks for watching.
Mike
Interested in going with an assist. Learning all I can . Thanks for teaching us.🇺🇸
You’ll love the hydro-assist. I replaced my PSC Big Bore HD box two years ago when I put the LS in my Jeep and went to 37’s.
Thanks for watching.
Mike
Just subscribed to your channel! Great video and you have one Awesome shop as well ! Thx for sharing !

Thank you very much for subscribing and taking the time to watch and comment.

Nice video. Thanks!
Thanks for watching.
Mike
That is exactly the next mod that I'm gonna do. Awesome video!! I was considering the PSC pump as well. Let us know how it goes with the stock one.
It worked fine with the stock pump right up until I removed it and installed hydro assist. I really liked the PSC HDII gearbox but it wouldn’t work with my LS engine that I recently installed due to its large case.
Thanks for watching and commenting.
Mike
@@zmotorsports62 Great video as always! Did you end up going to Hydro Assist? If so, did you video that install? Thanks!
Thank you Paul.
Yes, I did go with hydro assist when I put the LS engine in but I didn’t do a video on it, sorry. I used a Redneck Ram kit.
Thank you for taking the time to watch and for the comments.

Hi mike another great project.
I'm setting up my shop in Oregon
I build automatic transmission, love your shop set up if you don't mind what size plate did you use on your bench top
And are you happy with your hoist is it a 10/12k I am looking at rotary/ challenger I do mostly 3/4 1 ton truck stuff
Thanks for the comments Mike. Good luck and congrats on setting up your shop.
My fabrication table measures 32” deep x 60” long x 32” tall and is built from 1.5”x .188” wall square tubing. The top is supported with additional tubing then the 3/8” thick top was welded on. Built it about 15 or so years ago and it has worked out excellent. I also use it for other things than welding/fabricating so no holes. When I build a transmission I roll it adjacent to my workbench and lay components out.
My lift is an Ammco 10k pound. The Challenger Versalift is very similar as I was told they were built in the same factory and sister companies. It lifts my Duramax easily.
Thanks again for commenting and taking the time to watch.

How'd the stock pump and cooler hold up over the years? Thanks for the video.
I no longer have the PSC HD gearbox as it would not fit with my 6.2 liter LS engine so I went back to the OEM steering gearbox but had it ported for hydraulic assist when I swapped engines.
I still have the stock pump however and it has performed flawlessly, even with 37's. I also have the same small auxiliary cooler that I installed when I did my PSC HD box with the hydro-assist setup.
Thanks for taking the time to watch
Mike
@@zmotorsports62 Thanks for the quick response. Congrats on the LS swap! Cheers!
Happy to help.
Dude, how does the original steering box gear end up next to the new one? did you take it out?
I had swapped the OEM box out for the PSC XD several years ago. I then had to swap in a ported OEM box when I installed my 6.2 liter LS engine as the PSC box was too large. I used the OEM box and ported it for hydro-assist.
Hi Mike, can you provide part numbers and/or links for the cooler, hose and fittings please
Here is a link to the Derale cooler
www.summitracing.com/parts/der-13260
The fittings are just 1/4” NPT barb fittings and transmission cooler hose. I also prefer to use Oetiker style clamps rather than worm clamps.
Good video - this is on my short list. Everything still working out well ?
Yes, the box is working out great. It’s been working out great on and off-road.
Thank you for taking the time to watch.
Mike
Do you do outside fixes or is it all just your own stuff, just wondering?
Both. I don’t take on as much work as I used to when I had my business but I still take on an occasional side job for friends here and there when I have time and if it’s something I’m interested in doing.
Thanks for watching.
Mike
Did you do just the steering box or the full kit without the ram?
I originally used just the HD box but six months later when I installed my LS engine I found out it wouldn’t fit due to its size so I switched back to OEM steering box with West Texas Off-Road’s ram assist. I’ve been running that setup for the past nearly two years and 24k miles now. I love this setup and works great with my 37” tires.
Mike
Ok, thank you.
What technique do you use to maintain the toe adjustment. I.E. keeping the steering wheel centered and not impacting air bag clock sensor?
Those are actually two different things. Toe doesn’t change because you are not disconnecting nor altering the tie rod itself. The drag link (from pitman arm down to right steering knuckle) will have to be adjusted when finished.
I disconnect the steering column input from the gearbox being careful not to rotate it while removing/installing the gearbox as you can damage the clockspring if you turn it much while disconnected.
Upon reinstallation of the steering input on the gearbox after installation I merely loosen the clamp on the drag link and adjust it getting the steering wheel close then tweak it as needed during the road test to get it spot on.
Hope that makes sense.
Thanks for watching.
Mike
zmotorsports your right, I didn't word that very well, but you answered my question, thanks
Glad to help.
Again, thanks for watching.
Mike
Hello! I've just installed a Hydro assist PSC to my rubicon 2016... since then, the steering gear box is leaking from the top, not the connections, it seems to be from the screws on the top of the sector shaft, also I can hear a sound that seems to come from the box... do you have any ideas what's going on? i will appreciate any helps! (The PSC hydro assist is brand new)
Leaking from the top must be the gasket. Thus is somewhat common.
No idea on the noise.
Mike
@@zmotorsports62 Thanks, I will check the gasket up... Hope the sound stops when fix the leaking... great video, very clear explanation and your shop looks stunning!
Thank you. It’s doubtful the noise will stop with fixing the leak. In my experience noises aren’t usually associated with a mere leak. I would continue to research the noise.
Mike
@@zmotorsports62 I see Mike... Hope you can share what you find out, would be great; Regards!

Hi Mike. I bit the bullet and installed the Big Bore box on my JKU and you are absolutely right that it is a heavy bastard. Would you be willing to fab me up a pair of those cooler brackets that you made to install your cooler? I would be willing to compensate you for your time, materials and shipping. I do enjoy your videos.
Thank you. If I can get some time to I would be willing. I’ll have to measure the tube and spacing again as I can’t remember the dimensions.
I appreciate the comments.
Mike
@@zmotorsports62 I would be all in if you are willing. Please let me know. Thank you.
I will get back to you when I have a few minutes for measuring and fabricating.
Mike
How does the stock power steeering pump run with this big bore steering box?
It worked fine with the OEM pump on the 3.8 liter engine and 35” tires.
However, I no longer have the PSC HD gearbox in my Jeep. It wouldn’t work with my 6.2 liter LS engine so for the last two years I’ve been running my OEM pump and ported gearbox to work in conjunction with a 1.5” hydraulic assist ram. This setup works fantastic with the 37” tires I’m now running.
Mike
@@zmotorsports62 Im running the 3.6 jku and I've heard a bunch of different things about stock pump not putting enough PSI out or being able to keep the power steering fluid cool. Its one of those I have to test for myself then I guess
I installed a Derale 14” heat sink style cooler for my power steering years ago and haven’t experienced any steering issues since. Although a cooler really isn’t necessary with my hydraulic assist ram I just left it in place as extra insurance against heat.
Mike
Hey how much of a difference have you felt so far? Does it make steering any better or just stronger?
I’ve actually removed and sold my PSC Big Bore HD gearbox and have hydraulic assist steering now. I only had the HD gearbox for about 8 months but I liked it.
The HD gearbox was a big step up in strength and gave me peace of mind when off-road as well as improved steering. I can say I would recommend it based on the fairly short time I had the gearbox on my Jeep.
Thanks for watching.
Mike
Awesome thanks. Is hydro assist way better? And why did you go full hydro assist?
I didn’t go full-hydraulic as that is not DOT approved/legal, I went hydraulic assist. This places the small (1.5”) hydraulic ram parallel with the tie rod taking the weak sector shaft out of the equation. It basically turns the steering gearbox into a hydraulic valve directing the fluid to the hydraulic ram in either direction putting the force directly on the tie rod and steering knuckle.
Personally for light wheeling on 37’s and smaller the Big Bore HD II gearbox works great but for more aggressive wheeling on 37” and larger tires I would recommend hydraulic assist, especially with a front locker.
I removed mine because the gearbox is physically larger than the first generation PSC Big Bore gearbox and it wouldn’t work with my 6.2 liter LS engine strictly due to size.
I really like the hydraulic assist. It works great with the V8 engine and 37” tires regardless of whether cruising down the highway or crawling in Moab.
Mike
Awesome man thanks for all the feedback I appreciate it. I hear hydro feels a lot different as well. I was looking into the synergy sector shaft brace for some extra strength I have a high steer set up right now.
You are very welcome.
In my experience if you go too large of a ram on hydro-assist it can create a numb or unresponsiveness feel to the steering but if you stay with the smaller ram I feel no real difference other than it isn’t as quick to turn at low RPM but not sluggish or anything like that. I still get very responsive driver feedback when cruising down the highway.
I daily drive mine and I love the hydro-assist both on and off-road. My wife even takes the Jeep on occasions hasn’t reported back any adverse feeling of responsiveness.
I hope that has been helpful.
Mike
How long did the tear down and install take?
If memory serves only a couple hours. Not a bad replacement/upgrade at all.
Thanks for watching.
Mike
Any reason you didn't opt for the high pressure pump?
I want to test it without and see if it’s really necessary. I’ve heard both ways and want to test performance myself. I don’t trust some of the reviews or feedback that I have seen.
Thanks for watching.
Mike
zmotorsports Cool. I'm with you I also like trying stuff on my own. Thanks for posting your install.
You’re welcome.
Thanks for the comments.
Mike
So how has it performed with the stock pump?
So far so good. I have a couple week long Jeep rally’s coming up so those should be a pretty good test.
Mike
Any updates on your setup?
Still working great. I’ve been impressed with the steering off-road and aired down.
Looks like you might have a oil leak on your front seal.
Raul Angel Fonseca your a little late to the party. This mod was well over a year ago and I’ve regeared again since then for my 6.2 LS engine swap in which I replaced axle seals.
Thanks for watching though.
Mike
you need to show more wrench work and less talking.
