Truck Differential Parts.

We Use Only Genuine OEM Truck Differential Replacement Parts.

Our extensive rebuilding process consists of 12 hour tank cleaning, careful tear-down and inspection of each and every part. The disassembled parts are then thoroughly tank cleaned in high pressure steam cleaners to remove all oils and sludge. Each part is again inspected and gauged for any signs of wear, cracks or damage of any kind. All worn items are replaced with genuine OEM replacement parts. Once the entire unit has passed this inspection and all necessary parts are replaced the batch goes through a second inspection process by yet another technician and is then assembled with all the needed replacement parts and additional new parts, such as a gear set, a bearing kit, small part kit and bushing kit a seal kit and more. Once the unit is fully rebuilt we re-inspect it and then it goes to dyno testing to check for gear noise Etc.

These added procedures combined with our many years of remanufacturing experience equates to a long lasting and reliable differential you can count on for many years to come.
