TruXedo TRX-547901 Lo Pro QT Soft Roll-Up Tonneau Cover Black 6'4" Bed with RamBox

The TruXedo Lo Pro QT (TRX-547901) is a soft roll-up tonneau cover engineered specifically for truck beds equipped with RamBox. Widely recognized as North America's top-selling roll-up truck bed cover, the Lo Pro QT delivers a signature low-profile look, all-season weather protection, and hassle-free everyday use.

Ultra-Low Profile Design

Unlike most soft vinyl covers that sit on top of the bed rails, the Lo Pro QT mounts its angled aluminum tracks inside the bed rails. The result is a dramatically lower profile — the cover sits only 3/4 inch above the truck bed — preserving the clean, factory lines of your truck while improving aerodynamics and fuel efficiency.

Patented All-Season Tensioning System

The Lo Pro QT features TruXedo's patented automatic tension control with a self-tensioning spring adjuster and floating Hook-and-Loop fasteners that run the full length of the bed rail. Unlike traditional tonneau covers that loosen or sag in temperature extremes, this system keeps the cover taut and drum-tight year-round, from -20°F to 120°F.

Key Features:

• Cover sits only 3/4 inch above the truck bed rails — lowest profile of any soft roll-up cover
• Industrial-strength leather-grain vinyl fabric — tear-resistant and weatherproof
• Robust aluminum frame rails mount inside the bed for a streamlined appearance
• Patented self-tensioning spring system maintains a tight, consistent seal in all conditions
• Floating Hook-and-Loop fasteners eliminate snaps and adhesives that can fail
• Full-perimeter rubber weather seals keep cargo dry in rain, snow, and dust
• Provides full 100% bed access — entire cover removes in seconds without tools
• No drilling required — clamp-on installation with included hardware
• Mounts inside the bed rails, keeping all stake pocket holes accessible for accessories
• Bed locks with the factory locking tailgate for added cargo security
• Compatible with under-the-rail and spray-on bedliners
• Designed for 6' 4" truck beds with RamBox storage

Installation

The Lo Pro QT installs using a straightforward clamp-on system that requires no drilling, no special tools, and no cutting. All necessary mounting hardware and installation instructions are included. Most installations are completed in approximately 30 minutes using conventional hand tools.
