Add support to your Chevy or GMC bed channels
Give the rear bed channels extra reinforcement for the stresses of loaded and off-road use. These ADD stiffeners add steel support in the channel area, with useful extra attachment positions for your equipment.
SKU: AC1402501NA
A stiffener and backer plate work together
Each reinforced position combines a 3/16-inch steel stiffener and a 3/16-inch backer plate, adding 3/8 inch of steel across that arrangement. It is designed to support the bed-channel area where loads, bed equipment and rough-ground use can put stress into the bed.
Useful accessory positions
The brackets have provisions for an antenna or flag and additional tie-down points. Two-stage Hammer Black powder coat finishes the steel, and the set is made in the USA. It fits the listed applications across their bed lengths, excluding the CarbonPro bed.
Allow for drilled fixings
Installation requires drilling the marked holes and fitting supplied rivet nuts. Use the exact guide for the listed arrangement and a suitable rivet-nut tool. Any antenna, flag or other attachment is purchased separately.
The set supplies the driver and passenger bed-channel stiffeners with their backer plates.
