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.

Perfect fit for my 2008 Canyon
I was worried about fitment since I’ve had issues with universal liners before, but the CC5U04 dropped right into my GMC Canyon like it was made for it—because it was. All the stake pocket holes line up perfectly, and the wheel wells match exactly. Installation took me about 20 minutes by myself.

Tougher than I expected
I use my Colorado for landscaping work and this liner has taken a beating from shovels, rocks, and heavy equipment for eight months now. No cracks, no warping, and it still looks nearly new. The textured surface actually does keep mulch bags from sliding around during transport.

Great under-rail design
I specifically wanted a liner that didn’t cover my bed rails, and this one sits perfectly underneath them. My truck still looks stock but the bed is protected. The material feels thick and substantial, not flimsy like some spray-in liners I’ve seen crack on other trucks.

Easy installation, solid protection
The drop-in design made installation foolproof—no tools needed. It’s heavy enough that it doesn’t shift around when I’m hauling lumber or tools. Only minor issue is cleaning under it requires full removal, but that’s true of any drop-in liner.

Handles extreme temperatures well
I live in Montana where we see both -20°F winters and 95°F summers. This liner hasn’t cracked or become brittle through two full years of temperature swings. It stays flexible enough to remove for cleaning even in cold weather, which my previous liner didn’t.

Worth every penny for bed protection
After seeing what cargo did to my friend’s unprotected truck bed, I knew I needed a quality liner. The CC5U04 has saved my paint job multiple times already. Dropped tools bounce off it, gravel doesn’t scratch through, and cleaning is simple with just a hose.

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.
