I have a 89 k5. It has 10 bolt front and rear. It currently has 2:42s under it. I have some 35s MTRs I want to run. I live in CA. and my new beast is in Texas. The real only time I will take it to the mud is 2-3 times every couple of months nothing major. I just want to know if I should replace the gears and if so what should I replace them with. Any help is greatly appreciated.
