Description

This Zumbrota Performance Axle (ZPA) front axle assembly for Dana 30 differentials is designed as an OE replacement but with enhanced strength for demanding use cases like larger tires, higher horsepower, or heavier towing. It features aftermarket gear upgrades and can be customized with limited slip differentials or lockers. The assembly is rebuilt to high standards, with thorough inspections for straightness, cracks, and wear on all components. Bearings and seals are replaced, and gears are inspected for optimal tooth contact and correct rolling torque. It also includes high-quality nodular steel ZPA differential covers for protection.
