Rugged Liner CC5U04 Under-Rail Bedliner
Our CC5U04 under-rail bedliner is engineered specifically for 2004-2014 Chevrolet Colorado and GMC Canyon short bed pickups. This drop-in liner installs beneath your factory bed rails, preserving the truck’s original appearance while delivering impact-resistant protection to your cargo area.
We designed the CC5U04 with precision-molded construction that follows every contour of your truck bed, including wheel wells and stake pocket cutouts. The thick polymer material resists cracking in extreme temperatures and provides a skid-resistant surface that keeps cargo secure during transport.
CC5U04 specifications and compatibility

Precision Fit for Colorado and Canyon Short Beds
The Rugged Liner CC5U04 under-rail bedliner is custom-molded to match the exact dimensions of 2004-2014 Chevrolet Colorado and GMC Canyon short bed trucks. Unlike universal liners that require trimming and adaptation, our model-specific design ensures complete coverage from the bulkhead to the tailgate.
Every detail matters in our manufacturing process. The liner includes precision cutouts for all four stake pockets, allowing you to use tie-downs and accessories without modification. Wheel well contours follow the factory bed profile exactly, eliminating gaps where dirt and moisture might collect. This attention to detail means you get protection that looks factory-installed from the moment you drop it in.

Impact-Resistant Thermoplastic Construction
Durable Material Engineering
We manufacture the CC5U04 from heavy-duty thermoplastic polymer that absorbs impacts without cracking or splitting. This material choice stands up to dropped tools, sliding cargo, and the daily wear that comes with work truck use. The liner’s thickness provides a cushioning layer between your cargo and the painted bed surface.
The polymer formulation resists common truck bed challenges including gasoline spills, oil drips, and chemical exposure from work site materials. UV stabilizers prevent sun damage and fading even after years of outdoor exposure.
Drop-In Installation Process
Installing the CC5U04 requires no drilling, bolting, or permanent modifications to your truck bed. Start by thoroughly cleaning your bed surface and removing any loose debris. The liner drops directly into place, with alignment tabs and edge contours guiding proper positioning.
The precision fit means the liner stays in place through normal use without additional fasteners. Weight distribution across the entire bed floor and friction from the textured bottom surface prevent shifting during driving. Most installations take 15-20 minutes from unboxing to completion.

Common Questions About the CC5U04 Bedliner
Yes, the CC5U04 is specifically designed for 2004-2014 GMC Canyon and Chevrolet Colorado models with short bed (5-foot) configurations. The precision-molded design matches the exact bed dimensions for these model years.
If you have a 2015 or newer Canyon, you’ll need the updated CC5U15 model, which accommodates the redesigned bed dimensions introduced in the second generation.
No drilling or permanent modifications are required. The rugged liner CC5U04 under rail bedliner uses a drop-in installation that relies on precision fit and the liner’s weight to stay in place.
The molded edges and contours align with your bed’s natural shape, creating a secure fit without fasteners. You can remove the liner at any time without leaving holes or marks in your truck bed.
Yes, the CC5U04 includes precision cutouts for all four factory stake pockets. These openings align exactly with your truck’s stake pocket locations, allowing you to use tie-down anchors, cargo bars, and other stake pocket accessories just as you would without a liner.
The cutouts are molded during manufacturing to match factory specifications, so no trimming or modification is needed to access your stake pockets.
For regular cleaning, spray out the liner with a garden hose to remove loose debris. The textured surface releases dirt and gravel easily without requiring scrubbing.
For stubborn stains or ground-in materials, use warm soapy water with a stiff brush. The thermoplastic material resists oil and chemical absorption, so most substances wash away without staining. Avoid harsh solvents or abrasive cleaners that might dull the texture over time.
The CC5U04 provides a protective barrier between cargo and your painted bed surface, preventing scratches and dents that expose bare metal to moisture. This protection helps prevent rust from starting due to paint damage.
However, the drop-in design allows some moisture to reach the bed floor underneath the liner. For maximum rust prevention, ensure your bed is clean and dry before installation, and periodically remove the liner to clean and inspect the bed surface underneath.
We stand behind the quality of our CC5U04 bedliner with a manufacturer’s warranty covering defects in materials and workmanship. The warranty does not cover normal wear, improper installation, or damage from misuse.
The UV-resistant material and temperature-stable construction are designed for years of service under normal truck bed use conditions. Most owners report the liner maintaining its protective performance and appearance well beyond the warranty period.
Yes, the under-rail design of the CC5U04 is compatible with most tonneau covers and bed caps. Because the liner sits below the bed rails rather than covering them, your tonneau cover or cap mounts to the rails exactly as it would on a bare bed.
The liner’s thickness may slightly reduce bed depth by approximately half an inch, but this rarely affects tonneau cover operation. If you use a roll-up or folding cover that stores cargo in the bed, verify that the reduced depth accommodates your cover’s storage requirements.
