Additional Notes

*These caps commonly fit hubs that use a 4" threaded oil-bath cap. However, Dexter-branded caps should not be used on Lippert hubs, as the castle nut may contact the inside of the cap. Always verify the cap diameter and thread engagement before installation.

• Often used on Dexter HD oil-bath hubs
