Description

The USA Standard Gear ZA K630424 is a robust front inner axle engineered for GM 8.25-inch Independent Front Suspension (IFS) differentials. This right-hand side component features 28 splines and a precise length of 15.43 inches, ensuring proper fitment for maintaining drive integrity and handling responsiveness. Constructed from advanced alloys and subjected to state-of-the-art heat-treating technology, this axle offers superior durability and strength. This process enhances resistance to wear and fatigue, promising an extended service life. The component is finished to meet or surpass original equipment quality standards, making it a reliable replacement or upgrade. It is engineered to fit the 2004 to 2006 Chevrolet Silverado 1500 models equipped with the GM 8.25-inch IFS front differential, specifically the stub axle with a pilot for compatibility with a one-piece disconnect gear and sleeve.
