Description

The Zumbrota Performance Axle is a remanufactured rear axle assembly specifically designed for the AAM 11.5 axle. This unit comes equipped with a Yukon Duragrip limited-slip differential, offering enhanced traction and performance. The integrated 4.30 gear ratio is optimized for specific driving needs, providing a balance of acceleration and cruising capability. Furthermore, all axle tubes undergo rigorous inspection to ensure they are straightened precisely to OEM specifications, guaranteeing correct alignment and a seamless fit during installation. This rear axle assembly is intended for the 2003-2008 Ram 1500 Mega Cab, 2500, and 3500 SRW models. It is designed to integrate with the existing AAM 11.5 axle system, providing a direct replacement or upgrade path for owners seeking improved drivetrain performance and longevity.
