Build your 1968 - 1972 GM A-Body 12-bolt rear axle with components designed to handle serious performance use. Detroit Speed 075990DS is a pair of 33-spline axle shafts with Torino flange bearings, engineered to withstand extreme use in high-performance street, autocross, and track applications. The combination of high-quality alloy steel construction, a 33-spline design, and application-specific configuration makes these axle shafts an excellent foundation for a performance-focused GM A-Body rear axle assembly.
Detroit Speed induction heat treats and magnaflux inspects the 075990DS axle shafts to help ensure strength, quality, and reliability under demanding conditions. Torino flange bearings come already installed on the axles, eliminating an additional assembly step. The shafts use a GM 5 x 4.75-inch wheel bolt pattern with 1/2-inch-20 x 3-inch wheel studs. They are sold as a pair. Lug nuts are not included.
