What gears should i run?

3.91's with a 26-27"tall tire.:wav:

That is what I run and wish at times it had 4.10 gears....but then flat out 3.21 would be best. (could kill myself too, lol)

It depends on how high the engine can rev clean to, mine is 6,500 rpms...maybe built right it could have been 7,500 rpms.

If your motor like 5,500 rpms and no more then 3.91 are out..no more then 3.55 gears, maybe not even that.
