Description

The USA Standard Gear ZGK2254 Re-gear & Traction Kit is engineered to significantly increase the performance and traction of your differential in a single, convenient part number. Its durable construction includes a high-strength nodular case, forged 4320 chromoly spider gears, and composite clutches. USA Standard Gear maintains rigorous in-house quality control to ensure all gears meet strict dimensional, material, and fitment standards. This kit is ideal for those looking to upgrade to a more aggressive gear ratio and add a limited-slip differential simultaneously. It specifically includes components for applications with a 9.5-inch GM differential, 33 spline count, and a 12-bolt rear cover/ring gear. The included Master Install Kit ensures that all necessary components are present to get your vehicle back on the road quickly.
