Bearings Wholesalers develop and build a wide range of transfer kits for 4WD and AWD vehicles, providing the option of repairing rather than replacing transfer cases. Each Bearing Wholesalers transfer kit consists of high-quality components, individually selected for each vehicle application. Transfer cases are responsible for transferring power from the vehicle’s transmission to the front and rear axles via driveshafts in 4WD and AWD vehicles. In 4WD vehicles, transfer cases often include a set of low range gears designed for off road purposes, allowing the output shafts to rotate at slower speeds than the input shaft. All Bearing Wholesalers transfer kits come with all the components required to repair and rebuild the desired transfer case.
