During assembly, there may be some differential movement in the bulkhead. In
particular, DO NOT check mesh or diff movement without installing suspension
holders and securing bulkhead to the chassis. All parts have specifically designed
tolerances, and only when the car is fully assembled will it have the proper
amount of play where necessary. Check for free movement of all rotational
driveline components once the driveline and suspension are completely
assembled, as well as non-binding operation of the suspension components.
This Upgrade Kit includes reinforced Front & Rear Diff Bulkheads and Diff Height Inserts featuring new Labyrinth Dust Covers. Please follow these supplemental instructions during related assembly steps.
