USA Standard Gear Master Bearing Installation Kit

The USA Standard Gear Master Bearing Installation Kit line is a differential bearing kit (also called a ring and pinion installation kit or differential rebuild kit). It supplies the bearings and small parts needed to finish a ring and pinion gear set installation. Each kit is built around a specific differential application, so the correct parts come in one box.

Key Features:

• Uses premium Koyo/Timken bearings and races, chosen for durability in differential service
• Includes carrier bearings and races and pinion bearings and races
• Includes a pinion seal, crush sleeve or pinion nut where the application calls for them, plus marking compound with a brush for setting gear contact patterns
• Kit contents are matched to each application, with the manufacturer researching what each one needs
• Suited to shops and builders who already have shims on the shelf and want to save money over a full Master Overhaul Kit

Whether you're regearing for taller tires, towing, or a carrier swap, or just refreshing worn axle components, these kits give you the foundation for a reliable differential rebuild. USA Standard Gear is known for its wide range of drivetrain installation parts. Pairing a kit with a quality ring and pinion set helps the gears run quietly and last longer.
