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.

He will have doe very major issues. 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). Then there will be drive shaft angle
problems and you will need axle ratios of at least 5.38 to 1 or deeper
too. This is not to say it cannot be done but it is to say it will be
no easy task

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.

much completely replace your driveline with (at minimum) 1-ton axles,
heavy-duty transfer case/transmission, driveshafts, etc. I think you may
