High Quality Parts
With high-quality fluid from top names in the business, you know you are getting the best fluid available for your Mustang. Late Model Restoration has put together this kit with Royal Purple and Ford Racing fluids to keep your differential running smoother and quieter. With the included Lube Locker gasket, you can rest assured your differential will be sealed up to prevent leaks. This gasket has a built-in rubber seal so you do not need to apply messy RTV sealant.
Ford Performance Friction Modifier
Although Royal Purple has some friction modifier in it, the Ford rear ends needs a little bit more. This kit includes one bottle of friction modifier to provide smooth operation of clutch-type limited-slip differentials. The specially formulated additive eliminates rear end chatter for quiet operation.
If running an aftermarket differential cover, check the fluid capacity recommendation as more fluid may be required.
