With a 3" Rough Country lift, what TC drop spacing will I need, I measured and looks like 1-2 degrees max, how thick of a spacer is required to get to the right plane?

 

most 3" kits come with a 1" tranny drop so i'd guess around there.

or measure between your motor mounts and your TC mount, use that length, make a 1-2degrees right triangle and calculate the height difference.

no idea what the motor mount to tcase mount distance is, but at 36 inches it works out to .94 inches, so an inch seems pretty reasonable.

On that note i don't run one with my 3" lift and its my dd, but every jeep has different issues

 

I use mine to deliver 300 papers a day, roughly 75 mi, I can't keep seals in it and I have destroyed a set of u-joints in 7500mi. I'm willing to try anything!

 

Dang bro that sucks...i have a 96 with a 3 inch rough country lift...i dont run a t case drop or sye and i get no vibes ...
