Call summit, jegs, randy's ring and pinion, richmond gear,strange Anyone of them should be able to tell you. I know you can only go to a 4.56 on a 7.5 however you have a 8.5 and I think you can go as low as a 5 something. __________________ 03 Silverado ECSB, Dmax, Allison, 3.73 G80 96 Silverado ECSB, 350, 4L60E, 3.42 G80 89 Camaro, 5 speed, 4.56's, Powertrax Locker 49 F-1, flathead 6, 4 speed, 2wd, unknown rear end.
