Advice please: '90 YJ Conversion
Hello,
Can anyone point me in the direction of a complete conversion guide for a '90 YJ? I'm kind of new to it all, but I'm hoping to upgrade the following, along with anything else required to do so: -locking differentials (do I need these for both front and rear?), also probably axle upgrades. -40-42'' tires (Was looking at super swampers, but I might be on pavement too much to make them worthwhile), along with enough of a suspension lift. I get lost here, because the guides I usually see are for a maximum of 35" tires (are there laws against larger tires on the road?). -I have a freshly rebuilt stock engine (4.2L straight 6) right now, and I think I want to keep it. (I saw somewhere online that someone got away with 42"s and the stock 4.2). -I'm pretty sure my transmission is stock, would it need to be upgraded to handle the torque requirements of larger tires? I plan on using my rig mostly on desert/rocky trails and pavement, not so much for snow, and rain isn't much of an issue. I realize I'm a total newbie, but you've gotta start somewhere. All help is VERY greatly appreciated! Thanks! -Garrett |
Re: Advice please: '90 YJ Conversion
Tires that big on a Wrangler will require MAJOR suspension work and a
lot of fender cutting. Even 35-37" tires take quite a bit of work. If you are a total newbie to lifts in general, this might not be a good undertaking as your first lift project. That said, a spring over axle (SOA) conversion is the easiest way to get the lift you need, but there are drawbacks. You would probably need some lift built in to the springs in addition to the SOA conversion. SOA conversions also have the drawback of axle twist. My suggestion is that if you want to have this much lift is to Goggle SOA conversions and read up on them. There is quite a bit of info on the net.

Beside clearance there will be spring wrap up as stated, (really needs a 4 link setup) a need for much larger/stronger drive axle assemblies (even D60's front and rear would be a bit light for this).

Re: Advice please: '90 YJ Conversion
Agreed, not only will it take major suspension work, you will have to pretty
much completely replace your driveline with (at minimum) 1-ton axles, heavy-duty transfer case/transmission, driveshafts, etc. I think you may have the Pugeot trans, it's not even adequate for a stock application, never mind 42's. You're talking about serious coin and serious work.

Re: Advice please: '90 YJ Conversion
Do a spring over and put it on 33's. You'll love it and it won't break the
bank like going to 42's. A wrangler on 42's is completely assinine. You can run 33's on your stock axles, but you cannot lock the rear. To make your wrangler handle 32's is $6000. Minimum. My best advice would be to get a dana 44/ford 8.8 or XJ 8.25 and put it in the rear, locked up with a detroit, 4.56 gears. Get 4.56 gears and a selectable locker for the front. That traction and gear combination will turn 33's thru damn near anything without breaking the bank or a lot of parts.

Re: Advice please: '90 YJ Conversion
Do a spring over and put it on 33's. You'll love it and it won't break the
bank like going to 42's. A wrangler on 42's is completely assinine. You can run 33's on your stock axles, but you cannot lock the rear. To make your wrangler handle 32's is $6000. Minimum. My best advice would be to get a dana 44/ford 8.8 or XJ 8.25 and put it in the rear, locked up with a detroit, 4.56 gears. Get 4.56 gears and a selectable locker for the front. That traction and gear combination will turn 33's thru damn near anything without breaking the bank or a lot of parts.

"This is not to say it cannot be done but it is to say it will be

"A wrangler on 42's is completely assinine." -I've already got 31"s on there, I don't really want to do a SOA conversion and only increase my tires by 2". I made this page up a few months ago, http://garrett.loy.googlepages.com/wranglerconversion also, http://garrett.loy.googlepages.com/yjinfo basically what i still need to know is, -is there any kind of federal/state of CA law against having 40+ inch tires on a personal vehicle? or where would I find out? - "you will have to pretty much completely replace your driveline with (at minimum) 1-ton axles, heavy-duty transfer case/transmission, driveshafts, etc." given that I have the A/X-15, do I still require a new transmission/ transfer case? how about motor? Thanks! |

You will need stronger axles but stock drive train can live IF you gear the axles properly. Biggest mistake people make is that they refuse to run 5.38 or deeper gears with big tires like this and this places a LOT of strain on drive train and this is where the need for HD trannies and Tcase is born because they try to use a big engine and tranny gears or Tcase gears to overcome the big tires and tall gears. Also kong as you take the time to properly gear it it will do surprizing well with stock engine but I cannot stress enough that gears will make you or break you on this project. ----------------- TheSnoMan.com |
