ok got a new question I have read alout of the past treads about axles and upgrades I just want a clear and strait answer im creating enough lift to clear 36X13.50 might do 38 in the future I just need an axle that will not brake! under heavy off road use they will be locked. I know nothing is bullet proof not prone to braking often at all. I have a 1990 rrc with 10spline no lockers stock.
