Give your C5 or Z06 Corvette unbelievable acceleration with our exclusive 3.73, 3.90 and 4.11 Differentials. If your C5 currently has a 3.15 gear, you can expect almost a full second improvement in 1/4 mile ET's. C5's with a 3.42 gear can expect a .3-.4 tenth improvement in the 1/4 mile elapsed time. This is, no doubt the least expensive way to make your C5 run, as if it had major engine modifications, without spending major dollars. These units are professionally rebuilt using our New exclusive Ring and Pinion set. This assembly comes with a One Year Limited Warranty which covers ring and pinion set, seals and bearings. Parts are sold as an exchange.

A little information about Cryogenic Treatments:
Cryogenic hardening is a cryogenic heat treating process where the material is cooled to approximately −185 °C (−301 °F), usually using liquid nitrogen. It can have a profound effect on the mechanical properties of certain steels, provided their composition and prior heat treatment are such that they retain some austenite at room temperature. It is designed to increase the amount of martensite in the steel's crystal structure, increasing its strength and hardness, sometimes at the cost of toughness. Presently this treatment is being practiced over tool steels, high-carbon, and high-chromium steels to obtain excellent wear resistance. Recent research shows that there is precipitation of fine carbides (eta carbides) in the matrix during this treatment which imparts very high wear resistance to the steels.
