UnderCover UC1146 SE One-piece Truck Bed Tonneau Cover GMC Sierra 1500/2500/Sierra 3500 14-19 6'6"

The UnderCover® SE is a premium one-piece truck bed cover offering sleek styling, exceptional security, and unparalleled weather protection.

This tonneau cover is manufactured from premium ABS composite, ensuring a lightweight yet sturdy construction. UnderCover employs its patented X-Effect infrastructure, consisting of X-patterned bracing to prevent side-to-side and corner-to-corner flex with the cover open or weight on top. Aesthetically the UnderCover SE is also tough to beat, featuring aerodynamic molded style lines and a textured black finish.

The UnderCover SE offers exceptional weather protection thanks to its weather-proof EPDM rubber double bulb seal system, preventing moisture intrusion between the bed rails and cover. This cover is also highly theft resistant, featuring a keyed, low-profile lock cylinder to prevent unauthorized access to your valuables in the bed. And with the cover’s wrap-around lip, opening the tailgate without first unlocking and opening the cover is next to impossible.

Operating the UnderCover SE is quick and easy—just insert one of the two included keys into the cover’s low-profile, single-point locking system to release both side latches, freeing the cover. Integrated gas-charged struts do the heavy lifting for you, automatically raising the rear of the cover for comprehensive bed access.

Aside from good looks, superior security, and exceptional build quality, the UnderCover SE has a few more tricks up its sleeve. Integrated LED overhead lighting illuminates your pickup’s cargo area, shining light on your valuables for loading, unloading, and locating tools in the dark.

The UnderCover SE features a simple bolt-on installation—no cutting, trimming, or drilling is required. Coming in at a weight of only approximately 58 pounds, the UnderCover SE is as lightweight as they come. While we recommend a second set of hands for positioning the cover onto your truck’s bed, it’s light enough for a single individual to carry.

UnderCover is a RealTruck® brand, so when you purchase this tonneau cover or any other UnderCover product from RealTruck, you’re ordering directly from the manufacturer. We back the UnderCover SE Tonneau Cover with a 3-year warranty against manufacturing and material defects.
