Yukon 70-96 Chevrolet Caprice / 73-83 Chevrolet Malibu Re-Gear Kit - 8.5in Diff 30 Spline 4.11 Ratio

This Yukon re-gear kit starts with a 4.11 ratio ring and pinion set, designed to give your GM 8.5-inch differential a noticeable boost in acceleration. The 30-spline pinion gear is a solid foundation for this upgrade, and the kit includes all the necessary bearings with a 2.25-inch outer diameter, along with the required installation hardware. This package is built to enhance your vehicle's launching ability, providing that exciting "shot out of a cannon" feel many enthusiasts crave, especially when upgrading from a factory gear ratio.

This kit is a well-built solution for a wide range of GM vehicles, including popular models like the Chevrolet Caprice (1969-1996), Chevrolet Malibu (1973-1983), and Buick Regal (1973-1987), among many others. It's also a great option for hot-rodded vehicles that have been fitted with the GM 8.5-inch differential. The 10-bolt ring gear ensures compatibility with many common setups. By changing to a more aggressive gear ratio like 4.11, you're effectively telling your engine to spin faster for a given road speed, which translates directly into quicker starts and improved responsiveness off the line.

When undertaking a re-gear project, it's important to have all the correct components. This kit aims to provide that by including not just the ring and pinion gears but also all the essential bearings and installation hardware. This comprehensive approach helps ensure a smoother installation process and a properly functioning differential once completed. Remember to consult your vehicle's service manual or a professional mechanic for specific installation procedures and any additional components you might need for your particular application.
