Durable Performance Bearings

Motive Gear Differential Bearing Kits are designed to provide constrained relative motion between the gears. Made of high-strength steel, they're preloaded to withstand high torque and power while resisting wear and tear. Bearings are important components of any differential assembly; if possible, they should never be reused.

Standard Kits: Include front & rear pinion bearings, carrier bearings, pilot bearings where applicable, pinion seal & nut, gear marking compound, crush sleeve, brush, thread locking compound, and cover gasket or RTV.
Master Kits: Include Standard Kit contents plus ring gear bolts, pinion shims, and carrier shims.
Super Kits: Include Master Kit contents but with Timken bearings.
