Superior Axle and Gear's PA5770C axle shaft is manufactured for GM 12 Bolt Muscle Cars including the 1965 - 1967 Chevelle, 1967-1969 Camaro and the 1968 - 1972 Chevy II. This axle is manufactured in the USA using premium 4340 chrome moly alloy. This allows that axle to absorb energy without transfering sudden jolts to the ring and pinion and differential.

Superior's Evolution Series rear axle shafts are made in the USA and are designed with the serious competitor in mind. They feature rolled splines for longer life and proprietary heat treating. Superior axles are competition tough and will stand up to the punishment of today's off-road vehicles. Evolution rear axle shafts come with Superior's standard lifetime warranty.
