Description

The USA Standard Gear ZGK2080 is a comprehensive differential upgrade kit designed to enhance the performance and traction of your vehicle. This kit is specifically engineered for the Dodge Ram 1500 from 2007-2008 and the Ram 1500 in 2010, featuring a Chrysler 9.25" differential and a 3.55 gear ratio for the rear position. Included in the ZGK2080 package is a 3.55 ratio rear ring and pinion gear set, a master installation kit for a complete rebuild, and a 31-spline Yukon Dura Grip Limited Slip Positraction Unit. This unit is designed for maximum traction with a high-strength nodular case and forged 4320 chromoly spider gears, ensuring durability and reliability. The kit also provides 1.705" inside diameter axle bearings and seals. This upgrade is ideal for increasing your vehicle's traction and handling by combining a more aggressive gear ratio with a limited-slip differential. Whether for daily commuting or off-road excursions, the ZGK2080 aims to provide enhanced confidence and capability. Customer feedback suggests a significant transformation in truck feel and off-road traction after installation.
