Yukon 70-96 Chevrolet Caprice Limited Slip & Re-Gear Kit - 8.5in Diff 30 Spline 4.56 Ratio

Yukon Gear & Axle is known for making high-performance aftermarket drivetrain parts that are built to tough standards. This kit is designed to give your GM 8.5-inch differential a significant upgrade in both traction and acceleration. If you're looking to improve how your vehicle puts power down, especially if you've modified it or are rebuilding the rear end, this re-gear and limited-slip package is a solid choice. It's built to handle demanding use, proven in off-road competitions, so you can feel confident when you hit the road or the trail.

This kit includes everything you need to change your differential's gear ratio and add a limited-slip unit. You get a Yukon Dura Grip positraction unit, which helps send power to both rear wheels for improved grip, especially when cornering or on slippery surfaces. It also comes with a new ring and pinion gear set with a 4.56 ratio. This more aggressive ratio means your vehicle will accelerate faster from a stop, which is great for muscle cars or vehicles that need more punch off the line. The kit also contains all the necessary bearings and installation hardware, ensuring you have the right pieces for a proper rebuild. The ring gear is a 10-bolt type, and the bearings are 2.25-inch OD, fitting the GM 8.5-inch differential housing.

This re-gear and limited-slip kit is designed to fit a wide range of GM vehicles equipped with the 8.5-inch differential, including models like the Chevrolet Caprice, Buick Regal, and Pontiac Firebird. By changing to a 4.56 ratio, you'll notice a significant difference in acceleration. Keep in mind that changing your gear ratio will also affect your cruising RPMs on the highway, so consider your typical driving conditions when deciding on the right ratio for your needs.
