Yukon Gear Front 4340 Chrome-Moly Replacement Axle Kit For 79-87 GM 8.5in 1/2 Ton Truck and Blazer

If you're working on a 1979-1987 GM half-ton truck or Blazer with the 8.5-inch rear end, this Yukon Gear & Axle front axle kit is built to handle the demands of your vehicle. This kit replaces both the inner and outer axle shafts on the front axle, ensuring you have a strong, reliable drivetrain component for your truck or SUV. It's designed to fit a range of popular GM vehicles from that era, including models like the Chevrolet K10 and GMC K1500.

Yukon builds these axles using high-tensile strength 4340 chromoly steel, which is known for its exceptional toughness and resistance to bending or breaking under stress. They use advanced production methods, including cold-roll formed splines for better durability and advanced induction coil heat treating. This process creates a solid axle that's built to last, even in demanding conditions. The kit comes complete with Spicer U-joints, specifically the 1310/760X Series, which are well-regarded for their strength and longevity. You'll receive two outer axle shafts, each 9.94 inches long with 19 splines, and two inner axle shafts, one 19.15 inches long (right-hand) and one 35.46 inches long (left-hand), both with 28 splines.

This kit is a comprehensive solution for replacing worn or damaged front axle shafts. It's a well-built component designed for a direct fit on the specified GM 8.5-inch differentials, making installation straightforward for someone familiar with drivetrain work. Ensure you have the correct tools and refer to the manufacturer's installation instructions for proper assembly and torque specifications.
