Add on a durable .120 wall tubular Hoop Overrider to create the ultimate offroad bumper. These are some tough tubes! The RRC mount uses a unique D-ring attachment so you will need separate optional D-rings. The enclosed HDD-rings on the short base will not be used with these two tubular options. For use with 11540.10, 11540.11 and 11540.40 XHD Front Bumper Bases.
