About this kit
Truck Bed Cap, fitment-checked
Rough Country 73404 is a modular truck bed cap for 2019–2026 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks with a 5'10" bed. Measure from the bulkhead to the tailgate opening before ordering. It does not fit CarbonPro beds or Silverado and Sierra EV models, and it blocks cab-mounted cargo and digital rear-view camera use.
This truck bed cap for the 2019–2026 Silverado 1500 and Sierra 1500 arrives as a 6-piece modular assembly, so the panels go on in stages rather than as one lid. Full-opening gullwing side and rear doors, gas-strut assist, key-locking panels, exterior Molle panels, a tempered-glass rear door window, an integrated brake light, and a roof-mounted LED strip are all part of the design. Load rating is listed at 750 lbs static and 400 lbs dynamic. Rough Country lists install time at 4-6 hours, and a downloadable installation guide is available. Confirm your bed measures 5'10" first.
