What is included in the Yukon YGK2339 kit?

This kit contains a Yukon Dura Grip limited-slip differential unit, a 4.11 ratio ring and pinion gear set, and all the required bearings and installation hardware needed for a complete re-gear and LSD upgrade.

What is the benefit of the 4.11 gear ratio?

The 4.11 gear ratio is more aggressive than stock ratios found in many older vehicles. This means it will provide noticeably improved off-the-line acceleration and responsiveness, making your vehicle feel quicker.

Are there any special tools or fluids needed for installation?

Installation of a ring and pinion gear set and limited-slip differential typically requires specialized tools for setup, such as gear marking compound, pattern checking tools, and dial indicators. You will also need appropriate gear oil and possibly friction modifier additive, depending on the differential type. Refer to the manufacturer's installation instructions for a full list of requirements.

Product Details

When you're looking to significantly improve your vehicle's traction and acceleration, this kit from Yukon Gear & Axle is a solid choice. What you get in this package is a complete re-gear and limited-slip differential setup for GM 8.5-inch differentials. It includes a Yukon Dura Grip positraction unit, a new ring and pinion gear set with a 4.11 ratio for improved acceleration, and all the necessary bearings and installation hardware to get the job done. This kit is designed to fit a wide range of GM vehicles from the 1960s through the 1990s, including popular models like the Chevrolet Caprice, Camaro, and Impala, as well as many Buick and Oldsmobile models equipped with the GM 8.5" differential.

Upgrading your differential with this kit does more than just enhance grip; it's an opportunity to completely transform your vehicle's performance. The Dura Grip limited-slip differential ensures that power is distributed effectively to both rear wheels, especially during cornering or when traction is less than ideal. Paired with the 4.11 ratio ring and pinion set, you'll notice a substantial improvement in off-the-line acceleration, making your vehicle feel much more responsive. Yukon Gear & Axle is known for producing well-built drivetrain components that meet or exceed OE specifications, and this kit is no exception. The included bearings are 2.25-inch OD, and the ring gear is a 10-bolt design, ensuring compatibility with the specified GM 8.5" differential.

This comprehensive kit is ideal for anyone looking to rebuild or significantly upgrade their rear differential. Whether you're restoring a classic muscle car, building a hot rod, or simply want a more capable drivetrain for your truck or SUV, this Yukon kit provides the essential components. Remember to consult your vehicle's service manual or a professional mechanic for specific installation procedures and any additional parts or fluids that may be required for your particular application.
