Description

This performance rear axle assembly is designed for enhanced traction, higher speeds, and increased towing capabilities. It features aftermarket gear upgrades, a Yukon Duragrip limited-slip differential, and high-quality nodular iron differential covers for superior strength. Each assembly undergoes a rigorous remanufacturing process, including inspection for straightness, cracks, surface wear, and testing of internal components. All bearings and seals are replaced, and gears are precisely set for optimal tooth contact.
