How low I can drop my transfercase

I added a 6" lift on my 90 YJ, how low I can drop the xfercase to eliminate the vivs and not cousing any problems.


90YJ, 4.2/Auto, 4.56/D44 f/r, 35" Procomp, high steer.

Until the valve cover hits the firewall or the fan blades rip into the radiator [img]images/icons/crazy.gif[/img] I'd say about 1-1/2" is the practical limit. Maybe a CV driveshaft is in order?

Re: How low I can drop my transfercase

I'm still waiting for the Short Tails Shaft Convertion for the NP231. For the mean time I like just to drop as low as I can so I can drive it.

Re: How low I can drop my transfercase

About an inch is the norm, and the max I'd drop mine. 6" lift, no SYE and stock driveshafts = no wheeling!

AllLockedUp ... If you have 6" lift you only drop yours 1"
do you have vivs problem? Right now I drop mine 2" looks like the drive shaft kinda steep, but I'll need to test drive it and see.

Re: How low I can drop my transfercase

The thought of dropping the t-case and reducing ground clearance makes me ill. Here there are those of us that are constantly looking for clearance and ways to make more. Find another alternative!!!!

Re: How low I can drop my transfercase

Your never going to be able to drop the t-case enough to stop the vibes. About the only way your going to get rid of them is to go with the CV driveshaft. Trust me on this one....I spent many many hours trying to get rid of the vibes with shims and t-case lowering kits.....And I only had 3" of lift.

Re: How low I can drop my transfercase

Yep -mine is only dropped an inch. I don't have any vibration either - when I set up my D44 in the rear, I changed the pinion angle to match and also had new shafts made because the D44 has a pinion housing that's about 2" longer than the stock Model 20 rear.

2" is too much. I have no problems with clearance (running 36" tires).

Maybe in NH you don't! [img]images/icons/laugh.gif[/img]. Folks with 36s and a flat skid plate get hung up all the time here. [img]images/icons/crazy.gif[/img]
