Description

The Zumbrota Drivetrain ZA K630839 is a comprehensive rear axle kit engineered for GM 55P differentials. This kit is specifically designed for the rear axle with a right-hand shaft position and features 17 splines. The included axle shaft measures 30.25 inches in length and is manufactured using advanced heat-treating processes, resulting in a stronger and more durable component that meets or exceeds original equipment (OE) quality. This kit provides all the necessary components for a complete axle replacement, including the axle shaft itself, a wheel bearing, a seal, studs, and lug nuts. The USA Standard Gear components are built to rigorous standards, ensuring reliable performance and longevity. The item is explicitly noted as 'Not Corvette' and is intended for rear axle applications.
