AEV JK250 and Axles
#11
Do the 4.10s. If available, do 4.56. I have 3.73s running with 33"s and although doable it suffers off-road at high altitude. I'll be re-gearing with the next set of tires. Also, AEV is selling a package, not just a suspension as alluded to above. A big part of that "package" is the AEV name. AEV is very protective of its reputation. They won't let a slug roll out their doors wearing their name, hence the insistence on the re-gear.

Could be that 35s and 3.73s cause the transmission to "hunt" for the right gear causing excessive wear. Idk that for a fact but who knows what jeep engineers have told them and they do have to warranty this since u bought this package. I personally wouldn't want higher than 4.10s.
