Yukon 70-96 Chevrolet Caprice / 73-83 Chevrolet Malibu Re-Gear Kit - 8.5in Diff 30 Spline 4.56 Ratio

This Yukon Gear & Axle re-gear kit features a 4.56 ratio, which is a notable change from stock for many GM vehicles. This ratio is ideal for improving a vehicle's launching ability, giving you that "shot out of a cannon" acceleration many enthusiasts desire. The kit is designed to work with the GM 8.5-inch differential, a common unit found in a wide range of vehicles from the late 1960s through the 1990s, including models like the Chevrolet Caprice, Chevrolet Malibu, and Pontiac Firebird Trans Am.

Inside this kit, you'll find a well-built ring and pinion gear set, along with all the necessary bearings and installation hardware to complete the job. The pinion gear has 30 splines, and the ring gear has a 10-bolt pattern, ensuring proper engagement within the differential housing. The included bearings have a 2.25-inch outer diameter, which is specific to this differential size. Upgrading your gear ratio with a comprehensive kit like this can significantly change how your vehicle performs off the line, making it a popular choice for muscle car builds and restorations.

When undertaking a re-gear project, it's important to have all the correct components. This kit aims to provide that, simplifying the process by bundling the gears, bearings, and hardware together. Ensure you consult the manufacturer's installation instructions for specific details regarding the setup and adjustment of the new ring and pinion gears.
