2nd (1996-2002) and 3rd Generation Vipers can also be fitted with M-W packages. A 300M half-shaft assembly, which uses the OEM 108 mm CV joints, is available. For ultimate reliability Viper owners can opt for a complete package with 128mm CV joints.

Williams also offers a drag race package that utilizes a special 35-spline spool, special CV flanges, half-shafts, CV joints, outer flanges, and requires reworking the factory hubs. It has been proven effective and reliable by Viper racers who have recorded 1/4-mile times in the 7s at over 180 mph.
