BackRack Side Rails for 21-Inch Wide Toolbox (20-25 Sierra 3500 HD w/ 8-Foot Long Box)Find parts that fit my vehicle

SERIOUS STRENGTH: We get it. You do not want Siderails that try to look tough but have no purpose. BACKRACK Siderails are industrial grade and designed for trucks that push the envelope of on-the-job abuse. Heavy gauge HRPO tube is fully welded to an angular base that runs the full length of your truck bed. We expect you to overload your truck. BACKRACK Siderails are ready to handle whatever you bring to the job site. RUGGED GOOD LOOKS: If it wears the BACKRACK brand name it has to be work ready, but it can still look good while getting the job done. BACKRACK Siderails are designed to compliment the angles of our Cab Guards. Siderails install with or without our Cab Guards and are fully compatible with Crossbed Toolboxes. SIMPLE NO DRILL INSTALLATION: Drop them on and bolt them in. It is almost that simple. Once you secure the custom Stake Pocket Bolts into the stake holes, the Siderails drop into the pockets over the bolts. Turn down the nuts with a ratchet, and finish the installation by inserting the plastic caps inside the stake holes to hide all the fasteners. Very slick. TOOLBOX FRIENDLY: BACKRACK Siderails are available for both 6.5 ft and 8 ft bed lengths. The Tube Rail is available in two configurations: the FULL RAIL, which extends the full length of the truck bed and the TOOLBOX RAIL, where the Tube Rail stops short to accommodate the insertion of a cross bed Toolbox.
