Description

The USA Standard Gear ZGK2099 is a comprehensive differential re-gear and traction kit engineered to significantly enhance the performance of your vehicle's differential. This all-in-one package combines a performance-oriented 4.11 ratio ring and pinion gear set with a Yukon Dura Grip clutch-style limited slip positraction unit, providing both aggressive gearing and smooth, reliable traction across various terrains. The Yukon Dura Grip is built for longevity with a high-strength nodular case, forged 4320 chromoly spider gears, and composite clutches, ensuring it is completely rebuildable and ready for demanding use. This kit is specifically designed for applications featuring a 12-bolt rear cover and a 12-bolt ring gear, with a 9.75" ring gear diameter. All necessary small parts are provided, enabling vehicles to be quickly returned to the road. The package also contains axle bearings and seals, carrier bearings and races, pinion nut and seal, crush sleeve or preload shims, ring gear bolts, carrier and pinion shims, cover gasket or silicone, pinion shims, and head and tail bearings, making it a true one-stop solution for differential upgrades. USA Standard Gear prioritizes rigorous in-house quality testing and inspections to ensure all gears meet strict dimensional, material, and fitment standards. Available in a wide array of OEM and aftermarket ratios, these ring and pinion sets are built to withstand the demands of daily commuting, trail running, and spirited driving. The ZGK2099 kit offers a convenient and affordable way to increase traction by upgrading to a more aggressive gear ratio and incorporating a limited-slip differential in a single, easy-to-order part number. The included instruction manual and available technical support further assist in the installation process.
