Setting up a bed rack on a Chevy Colorado starts with loose assembly of crossbars and uprights, seating the mounting hardware on the bed rails, then leveling and torquing every fastener once the rack is squared.
Here is how to install a bed rack on a Chevy Colorado: it takes about an hour with basic hand tools, and most modern kits require no drilling—provided you check the stake pockets first. This guide covers the complete sequence that works for 2015–2025 Colorado and Canyon models from RCI, Victory 4×4, and TRUKD. One overlooked step—trimming unopened stake pocket plugs—stops the whole job cold on earlier trucks, so that gets covered first.
What Tools Do You Need for a Bed Rack Install?
Gather everything before you start so the install moves without interruptions. The hardware kits from RCI and Victory 4×4 use the same fastener sizes, so this tool list works for both.
| Tool | Where It Gets Used |
|---|---|
| 7/32″ Allen Wrench | Crossbar and faceplate hardware |
| 3/16″ Allen Wrench | Smaller set screws and trim bolts |
| 9/16″ Socket + 9/16″ Wrench | Carriage bolts, hex nuts on uprights |
| 1/2″ Wrench + 1/2″ Socket | Main leg-to-bracket fasteners |
| Phillips Screwdriver | Bed lighting bezels if your truck has them |
| Speed Wrench / Box End Wrench | Reaching crossbar nuts in tight spots |
| Utility Knife | Trimming stake pocket plastic plugs |
How to Install a Bed Rack on Your Colorado
The sequence below follows the manufacturer procedures used by RCI, Victory 4×4, and TRUKD. Check the PDF that came with your specific rack for torque values—these steps give you the method that fits most aftermarket kits.
Step 1 — Prep and verify the hardware. Unpack everything and confirm all brackets, bolts, faceplates, and washers are present. Measure your truck bed width so you can set the crossbar spread before assembly.
Step 2 — Clear the stake pockets. On 2015–2022 Colorado models, the stake pockets are often filled with a plastic plug that must be cut out. Run a utility knife along the molded trim lines and pop the plug free. Skipping this step makes the mount bolts impossible to seat.
Step 3 — Loosely assemble the rack. Attach the crossbars to the uprights and leg brackets using the supplied carriage bolts and washers. Keep everything hand-tight—do not torque anything yet, because the rack needs to shift as you square it.
Step 4 — Position and mount. Set the front and rear rack sections on the bed rails. Adjust the legs to match the bed width. For stake-pocket mounts, feed the bolts through the top slot into the pocket. For C-clamp mounts, wrap the long leg under the bed rail and lever the short leg over the top edge. Hand-tighten the clamps to hold position.
Step 5 — Square and level. Make sure both uprights sit at the same angle. Measure the gap between the rack and the bed side on each side—a consistent 1.25-inch gap tells you the rack is square. Confirm the top crossbars run parallel to each other.
Step 6 — Torque in order. Tighten all carriage bolts starting from the lowest fastener and working upward. Use a split washer where included to maintain tension. On C-clamps, stop at hand-tool tight—RCI specifies “hand tool tight,” and TRUKD sets a 15 ft-lb max. Exceeding that can shear the aluminum threads.
Step 7 — Add accessories last. Shovel mounts, light brackets, and similar gear go on only after the rack is fully secured and torqued.

Common Mistakes That Derail the Install
Ignoring the stake pocket plugs. This is the single most frequent issue on 2015–2022 trucks. If the bolt will not drop into the pocket, check whether the plastic plug is still in place and trim it out.
Tightening too early. Torquing crossbar or leg bolts before the rack is squared means you will have to loosen everything again to adjust. Leave all fasteners hand-tight until the rack is level and centered.
Over-torquing C-clamps. Aluminum C-clamp threads strip easily past 15 ft-lb. Use a hand wrench and snug them firmly—do not lean into a ratchet. The RCI installation guide is explicit about this limit.
Clamp spacing violations. Thule-style rear clamps must be no closer than 7 inches apart, and front clamps no closer than 3 inches. Tighter spacing compromises the grip on the bed rail.
FAQs
Do I need to drill holes in my Colorado bed for a rack?
Most modern aftermarket racks from RCI, Victory 4×4, and TRUKD mount without drilling. They use stake-pocket hardware or C-clamps that grip the bed rails. Older or custom heavy-duty units may still require drilling—check the product specs before buying.
Will a bed rack work with a tonneau cover installed?
Some racks interfere with tonneau covers, especially folding or rolling hard covers that sit flush with the bed rails. Low-profile racks or models designed for cover compatibility can work, but you may need to modify the cover or choose a rack specifically listed as tonneau-friendly.
How long does the installation take?
Expect about one hour for a first-time install with hand tools. The second time goes faster because the stake pockets are already cleared and you know the assembly order. Having a second person to hold the rack sections while you align them cuts the time by about 15 minutes.
