Product Details

This is the USA Standard 4340 Chrome Moly Inner Front Axle Shaft, designed for the left-hand side. You get one heavy-duty axle shaft, built from 4340 chromoly steel, ready to replace your worn-out original. It's 35.46 inches long with 28 splines, fitting GM 8.5-inch front differentials.

This axle shaft is constructed from high-tensile strength 4340 chromoly, a material known for its toughness and durability, especially under stress. Yukon Gear & Axle uses advanced heat-treating processes to further enhance its strength and resistance to fatigue. This makes it a solid option for trucks and SUVs from 1979 to 1987, including popular models like the Chevrolet K10 and GMC V1500. It's built to handle the demands of daily driving and more rugged use.

When you're rebuilding your front drivetrain, especially if you're looking for something stronger than stock, this inner axle shaft is a good choice. It's designed to fit right into your existing differential setup, making the installation process straightforward for someone familiar with axle work.
