This is a complete service kit to fully replace and service one complete Axle. Includes the following:
-1 Cap Install Tool -2 Vault Caps -1 Tube of Vault Grease -1 3oz. tube of RTV Black Silicone. (This is used in place of the normal O-rings as we have seen better results in fitment and longevity of the product. Recommended to add on the lip before installing and letting sit for 24hrs before towing.)
