USA Standard 4340CM Axle Kit For 79-87 GM Truck & Blazer / GM 8.5in / 30 Spline w/Super Joints

If you're working on a 1988-1991 Chevrolet Blazer or a 1988-1991 GMC Suburban with the GM 8.5-inch rear axle, this USA Standard 4340CM front axle kit from Yukon Gear & Axle is built to handle the demands of your truck. This kit replaces your front axle shafts, which are crucial for transferring power from the differential to the wheels, especially in 4WD applications. It's designed for a 30-spline configuration, ensuring proper engagement with your differential and hubs.

Constructed from high-tensile strength 4340 chromoly steel, these axles are put through advanced heat-treating processes. This combination creates a well-built and durable component that can withstand more stress than standard axles. A key feature of this kit is the inclusion of Yukon Super Joints. These are designed to offer a greater range of motion compared to traditional U-joints, which can be beneficial when your vehicle is lifted or operating at extreme suspension angles. This improved articulation helps prevent binding and potential breakage during hard turns or off-road articulation.

This axle kit is a solid option for those looking to upgrade their drivetrain for improved reliability and performance. It's a direct replacement for the front axle shafts on the specified GM trucks and SUVs, making installation straightforward if you're familiar with drivetrain work. Ensure you have the correct tools and refer to the manufacturer's installation instructions for proper fitment and assembly.
