surely standard ones will be fine.
been in 80 standard diffs on 35s no probs.

It will work but reduce your power output at the treads. From memory a 35" tyre changes your overall gearing about 12% so a 4.54 (10%) or 4.88 (16%) ratio would get you back on track.

if you're happy with performance don't bother changing though.

4.56:1 for std with 35's

4.88 to one to pick up around 150 rpm more at hwy speed.

I run 4.56 with 37's.

Dont leave them standard, makes the car a pig to drive, and less ecenomical.
