      Purchase a ring and pinion gear set for your 1965-79 Corvette series 3 carrier. We stock "U.S. GEARS" ring and pinions sets. With the exception of the Richmond 3:90 ratio.

These ratios are available 3;08, 3:36, 3:55, 3:73, 3:90 ratios we also have 4:11, 4:33, 4:56 thick gears that fit The 3 series carrier in a posi, locker, or spool. All of these gears fit our spool. If you want to determine the best ratio for your Corvette. These formulas should help. These formulas do not work for overdrive transmissions. You should figure an additional 10 percent RPM for automatics without lockup converters.     


To determine what RPM you'll be at for any given gear ratio and tire diameter:

MPH x Axle Ratio x 336 -- Divide that number by the Tire Diameter



To determine what speed you'll be going with a given tire diameter and gear ratio:

RPM x Tire Diameter -- Divide that number by the Axle Ratio x 336



To determine what axle ratio you'll need for a given speed and tire diameter:

RPM x Tire Diameter -- divide that number by the MPH x 336
