A 4.88 gear w/38's will yield roughly the same RPM per MPH as a 3.96 gear ratio on stock tires, and is probably the best combination of pulling and economy. Of course, economy is a relative term as the mass of the rotating assembly is about to be triple or more. Certainly not good for stop & go driving.

Hi Bill
so you recommend 4.56 if i want the same as stock`s performance with 38`s, but i didn`t understand the 4.88 very clear , can u explain it more please thanx
