This Corvette Rear Axle Kit is for the C2 and C3 (Circa: 1963-1982) Corvettes that originally have 17-spline axles. This kit replaces the wheel flange axle, universal joint flange, and the 4-bolt u-joint flange on the tubular rear axle drive shaft. The spline on the axle is increased to a more modern 31-spline with a 1.333” major diameter.
The C2 and C3 Corvette differentials come from the factory with a 17-spline inner flange yoke that can be prone to failure. Our solution is to upgrade the rear by modifying a stock Corvette posi-traction carrier with 30-spline side gears and adding a one-piece 300M 30-spline inner flange yoke shaft that eliminates the bolt-on flange yoke.
Mark Williams Enterprises has long been searching for a product that provides better corrosion resistance than commonly used WD-40 oil. M/W has always been skeptical of products with miracles through chemistry. However, GIBBS™ brand lubricant is the exception, and lives up to its claims. This product is the best bet for keeping unpainted dragster chassis tubing from rusting.
The new dual angular contact bearings reduce friction and increase RPM capacity. All assemblies are factory pre-load set to simplify the installation. These M-W exclusive bearings make pre-load adjustments easy for field service by allowing the removal of the front race.
Mark Williams now offers race-ready 3rd members equipped with a beefy 10” pitch diameter ring gear (trimmed to 9.5”) that can be employed in the popular 9” Ford style rear end housing. This setup is ideally suited to ultra high horsepower applications like Pro Mod.
These new 7075 alloy driveshafts are exclusive to MW, and feature our patented Accu-BondTM process for securing the yokes to the shaft. These are 61% stronger than our previous best, and can save approximately 50% of the weight over similar-sized steel shafts. Ideally suited for Pro Mod and other extreme horespower applications, these shafts are custom made and are balanced to G30 specifications at simulated operatiing conditions on our high-speed balancer.

Shot Peening
Mark Williams has been looking for current and new ways of making the best and strongest products available. We have been doing in-house heat treating for a long time. Now, we can do shot peening in-house, too. Shot peening enhanes the resistance to fatigue fracture and resistance to stress corrosion rather than strength or hardness, as does the heat treating process.
