8.8" REAR AXLE ASSY '99-'04 FORD MU

Zumbrota Performance Axles are designed for enhanced traction, higher speeds, and heavier towing. They are OE replacements upgraded with aftermarket ratios, limited slip differentials, lockers, and high-quality nodular iron differential covers. Zumbrota uses Yukon Gear & Axle products for performance and reliability. Each axle assembly is rebuilt to high standards, with thorough inspection for straightness, cracks, and wear. Internal components, including ring & pinions, gears, clutches, and carriers, are inspected and tested. All bearings and seals are replaced. Gears are inspected for optimal tooth contact patterns and correct rolling torque. The assemblies undergo an exclusive hydro-blast rinse, sandblasting, and proprietary shot-enticed deep cleaning.
