USA Standard 4340CM Axle Kit For 79-87 GM Truck & Blazer / GM 8.5in / 28 Spline w/Super Joints

Yukon Gear & Axle is well-known for building tough drivetrain components, and this USA Standard 4340CM front axle kit continues that tradition. If you're working on a 1979-1987 GM truck or Blazer with the 8.5-inch rear end and 28-spline axles, this kit is designed to get you back on the road with improved strength.

This kit uses high-tensile strength 4340 chromoly steel, which is a strong material chosen for its durability under stress. Yukon employs advanced heat-treating technologies to further enhance the axle's toughness and resistance to fatigue. The included Super Joints are built to handle more angle and torque than standard U-joints, making them a popular choice for lifted trucks or those that see heavy use. This specific kit includes the 19.15-inch inner left-hand axle with 28 splines, ready to be installed in your GM 8.5-inch axle housing.

This axle kit is a solid option for a range of GM trucks and Blazers from the late 70s through the late 80s, including models like the Chevrolet K10 Suburban, GMC K2500, and Chevrolet K5 Blazer. Ensure you verify fitment for your specific vehicle. This kit is designed as a direct replacement for the factory axle, simplifying the installation process.
