High-performance replacement axles for the Porsche 930 (28 spline). All axles are CNC machined, heat treated, and centerless ground for a consistent outside diameter. Splines have been enlarged by 3 inches to allow the CV to float on the axle and end diameters have been maximized to minimize wear between the axle and CVs. Available in a variety of lengths. Standard axle sets are manufactured out of aircraft grade 4340 and powder coated for corrosion resistance.
