The XL series hidden brackets attach to your GMC Sierra's frame to provide attachment points for your tow bar. The visible portions of the brackets can be removed when you are not towing.
Features:
The square drawbars, or front arms, on the XL series base plate kit are simple to mount and remove, easily securing with hitch pins. Once the drawbars have been removed, the remaining brackets are virtually invisible. On most automobiles, the brackets are mounted within the grille, where they remain not only unseen, but protected from scrapes and scuffs as well.
Frame Variance Measurement Diagram
Measurement must be taken from the centerpoint of the lower-most threaded hole, on the side of frame, to a center-line dissecting the rear-most elongated hole on the bottom of the frame.
