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

Inland Empire Driveline Service's products have passed Spicer grueling dynamic reverse torsion fatigue testing requirement.
One of the very few Spicer authorized aluminum drive shaft builders in the world.
Inland Empire Driveline Service also routinely makes proof tests in static torsion.

Note: ALL aluminum driveshafts will exhibit a metallic resonating noise that the original 2pc steel driveshaft naturally dampens. This is normal and will not affect performance, but if you are concerned about cabin noise, you may prefer a Steel Driveshaft, which still provides significant weight savings over the OEM driveshaft, but is going to run quieter than aluminum. Inland Empire now also offers a foam filling option for aluminum driveshafts, which significantly reduces noise and resonance without adding any noticeable weight. This is the best weight to enjoy buttery smooth operation while still getting the weight savings of an aluminum driveshaft. Please allow 3-5 days for shipping with this option.

Note: These are normally built to order, and ship out in 1-2 weeks directly from the factory.
