CZP By Inland Empire Aluminum Driveshafts are manufactured from custom drawn 6061-T6 D.O.M. aluminum tubes for consistent strength utilizing 6061-T6 aluminum forged weld yokes for strengthened grain structure. Internal stress induced by the machining process is reduced by working with the grain structure resulting in a more durable product. This reliability is enhanced by our "State of the art" welding processes. Our products have passed Spicer's grueling dynamic reverse torsion testing and have qualified us as an authorized aluminum shaft builder. Competition
