:huh: I want to put 4.88 gear in my 99 dodge ram 1500. It has the 9.25 rear end under it. I heard with the 4.88 gears that you may need to grind tooth or use notched crosspin for clearance. Is this true? Anybody running this gear? I can have two different gear ratios in my truck as long as i dont put it in 4-wheel drive right? Any info would really help me out. Thanxs.
