These caps are designed to seal the end of your D44 hubs when used as a 2wd setup. Our ball detent design eliminates the need to retain any of the internal 4x4 components to hold the cap on. These snap into the factory retaining ring groove and hold the cap firmly in place, essentially eliminating the need for tools to access your bearing nuts. No small screws or snap rings to fumble around with.
Precision machined in the USA from domestic 6061 material.
