Setting up a differential correctly is paramount when it comes to the longevity of your running gear. We have the tools and the knowledge to do anything from a simple bearing and seal replacement to complete ratio changes and locking carrier setups. We also have resources to build differentials on the more challenging Japanese and European vehicles. The market is flooded with cheap Chinese parts and we refuse to use any of them in our differentials. We hand select every ring and pinion, bearing, race and seal to make sure that they are the highest quality available.
