I have a 92 YJ with a 4 banger. I run 33 inch BFG mud terrain tires and have lockers front and rear. I want to upgrade my gears to 4.88s but my mechanic tells me that the pinion is too small in that ratio and much easier to break. Does anyone have any experience with 4.88s on the trail? Also, how are they on the freeway? I would also like to know what your RPMs are at 65.
Thanks for your advice.
