Description

The USA Standard Gear ZA K630209 is a rear axle kit engineered to meet or exceed OE quality standards for Ford 7.5 in. and 8.8 in. differentials. This kit provides all necessary components to replace, repair, or upgrade axle shafts, ensuring your vehicle is back on the road quickly. This axle kit offers a 31-inch length, a 28-spline count, and a 5-lug configuration, making it suitable for specific Ford, Lincoln, and Mercury rear passenger car applications from 1979 to 1989. The kit includes a 2.25-inch OD wheel bearing, seal, studs, and lug nuts, simplifying installation and ensuring all critical parts are included. USA Standard Gear emphasizes that their replacement axles are built for an exact fit and are easy to install. The advanced heat-treating process results in a stronger, more durable axle shaft, crucial for the demands of drivetrain components.
