The USA Standard Gear ZDS9520 is a brand-new front driveshaft, built from the ground up for GM Silverado and Sierra 2500/3500 trucks. Unlike remanufactured units, this driveshaft is constructed with high-grade steel and features new slip yokes, shafts, and maintenance-free universal joints, ensuring decades of reliable use. This driveshaft has a tube length of 27-1/8 inches from weld to weld and includes a MECH 3R universal joint at the differential with a 1.125-inch cap diameter.

The ZDS9520 is part of USA Standard's “Perfect Fit” program, meaning it arrives fully assembled and ready for installation, guaranteeing proper fitment and an easy replacement process to get your vehicle back on the road quickly. The USA Standard Gear ZDS9520 front driveshaft is specifically designed for 2001-2007 GM Silverado and Sierra 2500/3500 models equipped with either a 5-speed automatic or 6-speed manual transmission.
