Description

Zumbrota Performance Axles are engineered for lifestyles requiring stronger traction, higher speeds, and increased towing capabilities. This rear axle assembly features a GM 10.5" 14-bolt full-float design with a Yukon Duragrip limited-slip differential and a 4.88 gear ratio. Each axle is remanufactured to the highest quality standards, with all internal components thoroughly inspected and tested, including ring & pinions, internal gears, clutches, and carriers. All bearings and seals are replaced. The assemblies undergo an exclusive hydro-blast rinse, sandblasting, and proprietary shot-enticed deep cleaning for optimal performance and longevity. High-quality nodular steel ZPA differential covers provide enhanced strength and protection.
