Description

The Complete Kit GM 8.5in w/ Eaton / Auburn Posi from RATECH provides essential components for a limited-slip differential upgrade on GM 8.5-inch rear axles. This kit is designed for builders and mechanics seeking reliable traction control at an affordable price, making it suitable for street performance, off-road applications, or daily driving where factory open differentials may fall short.

This assembly utilizes proven limited-slip technology that biases torque to the wheel with the most traction during acceleration or cornering. It employs spring-loaded clutch packs and a helical gear set to provide smooth engagement during regular driving while maximizing power delivery when needed. The kit includes necessary bearings, seals, shims, and installation hardware, ensuring a straightforward installation process.

Ideal for those upgrading worn or damaged OEM differentials, this kit is also beneficial for anyone looking to enhance traction on modified vehicles with wider tires. It is compatible with various GM platforms, including Chevrolet and GMC, that feature an 8.5-inch axle housing.
