Sonnax new 6-bolt adapter flange yoke kits are an ideal upgrade for ’05–’19 Ford Mustang driveshafts. Specifically designed to bolt up to bolt circle diameter pinion flanges, the Sonnax yokes allow elimination of the OE CV joint. When used with a stub and slip assembly, they makes it easy to also eliminate the rubber guibo or “flex” joint, converting a two-piece driveshaft into a one-piece, U-joint style driveline.
