USA Standard Quick Kits

USA Standard Gear Quick Kits totally upgrade your differential in a single, convenient part number. These kits consist of four sub-kits, a ring and pinion gear set, installation kit with bearings, races, and small parts, a limited slip positraction unit, and axle bearings and seals.

USA Standard Gear ring and pinion gear sets can be ordered a number of popular gear ratios including 3.07, 3.08, 3.54, 3.55, 3.73, 3.92, 4.09, 4.11, 4.27, 4.56, 4.88, 5.13, 5.38, 5.89, and many more. USA Standard Gear uses state-of-the-art design and testing processes, backed by two in-house quality assurance labs, to ensure each gear set meets exacting engineering specifications: dimensionally, for metallurgy hardness via heat-treating, and for torsional strength. Quick Kits offer gear sets in your stock ratio or you may choose to upgrade your gearing to enhance the performance of your vehicle.

USA Standard Gear Master Overhaul Kits provide all the small parts and components needed to complete any differential job from start to finish. These kits use high-quality Koyo/Timken bearings and races and include carrier bearings and races, pinion bearings and races, a pinion seal, a complete shim kit, ring gear bolts, a pinion nut, a crush sleeve (if applicable), oil baffles and slingers (if applicable), thread locking compound, marking compound with brush, and a gasket.

Quick Kits include a limited slip positraction unit to upgrade the traction in your ride. When in their static state these limited-slip units are pre-loaded and provides traction to both wheels. When the LSD is further loaded… under acceleration, in a fast corner, or when wheel slippage occurs off-road… the unit’s clutch packs limit wheelspin across the drive axle by permitting the axle shafts to spin at different speeds while continuously trying to balance the application of torque between the two axles. This results in transferring more power to the wheel with the best traction.

Each USA Standard Gear Quick Kit includes high-quality axle bearings and seals to fully dress your diff in brand-new hardware.
