Description

The Zumbrota Drivetrain ZGK2146 is a comprehensive differential kit designed to provide a complete solution for rear-end upgrades. This kit includes a USA Standard Gear ring and pinion set with a 4.56 gear ratio and 35 spline count, making it suitable for applications requiring significant gear changes. This kit is specifically engineered for vehicles utilizing a 12-bolt rear cover and a 12-bolt ring gear configuration, with a 10.5-inch ring gear diameter. A key component of the ZGK2146 is the inclusion of a Yukon Dura Grip clutch-style limited-slip differential (LSD), known for its durability and performance. All Positraction units within this kit are fully rebuildable, offering long-term serviceability. The "Quick Kits" offered by Zumbrota Drivetrain aim to simplify the differential repair and upgrade process by providing a one-stop shopping experience. This approach ensures that customers can easily find the correct parts for common differential repairs at an affordable price point.
