Description

The USA Standard Gear ZA K630116 Rear Axle Kit is engineered to provide a robust and durable solution for your vehicle's drivetrain. Utilizing advanced alloys and the latest heat-treating technologies, USA Standard Gear ensures a strong axle capable of withstanding demanding conditions. This comprehensive kit is specifically designed for GM 8.5-inch differentials and features 30 spline count for enhanced strength. The axle measures 30-7/16 inches in length and includes a 5 x 4.75 inch bolt pattern, making it suitable for applications requiring precise fitment. The kit comes complete with all necessary components for installation, including wheel bearings, seals, a differential cover gasket, studs, and lug nuts, allowing for a quick and efficient replacement or upgrade. The application summary indicates fitment for the 1989-1990 Chevrolet Caprice models with Rear Wheel Drive (RWD), specifically noting its compatibility with the GM 8.5-inch rear axle. The included wheel bearing has a 2.25-inch outer diameter, and the hub diameter is 2.78 inches, ensuring proper integration with the existing setup.
