Yukon Gear 4340CM Right Hand Inner Axle For 79-87 GM 8.5in Blazer and Truck / Uses 5-760X U/J

Yukon Gear & Axle is known for making strong drivetrain components, and this 4340CM right-hand inner front axle is a great example. If you're working on a 1979-1987 GM truck or Blazer with the 8.5-inch differential, this axle is built to handle the demands of the road and off-road. It's designed to work with the 5-760X series universal joint, ensuring a solid connection for your drivetrain.

This axle is constructed from high-tensile strength 4340 chromoly steel, which is a well-built material chosen for its durability and strength. Yukon uses production methods like cold-roll formed splines, which help maintain the material's integrity, and advanced induction coil heat treating. This process creates a strong, reliable axle shaft that measures 19.15 inches long and features 28 splines, fitting right into your GM 8.5-inch differential.

This inner axle is a direct replacement for many GM trucks and Blazers from 1979 to 1987, including models like the Chevrolet K10 and GMC K1500. It's a solid option if you're rebuilding or repairing your front axle assembly and need a dependable component.
