11.5" AAM REAR AXLE ASSY '14-'18 RA

Zumbrota Performance Axles offer stronger traction, higher speeds, and heavier towing capabilities. This OE replacement is designed for vehicles with bigger tires, higher horsepower, or those that frequently tow. It features aftermarket ratios, limited slip differentials, lockers, and high-quality nodular iron differential covers. Zumbrota uses Yukon Gear & Axle components for performance and reliability. Each axle assembly is rebuilt to high standards, with thorough inspection of straightness, cracks, and wear. All internal components (ring & pinions, gears, clutches, carriers) are inspected and tested. All bearings & seals are replaced. Gear setup involves inspection for optimal tooth contact patterns and correct rolling torque. The assembly features an exclusive hydro-blast rinse, sandblasting, and proprietary shot-enticed deep cleaning.
