Description

The USA Standard Gear Chromoly Front Axle Kit, model ZA W24118, is designed as a robust upgrade for GM 8.5” front differentials. Constructed from heavy-duty 4340 chromoly, this kit offers enhanced durability over stock components. The kit includes a complete set of front axles for both sides. The outer axles feature 19 splines and a length of 9.94 inches. For the inner axles, both the left-hand (LH) and right-hand (RH) sides are equipped with 28 splines. The inner LH axle measures 19.15 inches, while the inner RH axle is 35.46 inches long. Additionally, the kit comes complete with 1310 Series u-joints. Installation note: This axle's diameter is larger than a stock 28 spline axle, and requires the YC G26010481 case for proper fitment.
