BAKFlip Revolver X4S Retractable Tonneau Cover
We built the BAKFlip Revolver X4S to give truck owners the ultimate combination of security and convenience. This retractable tonneau cover uses heavy-duty aluminum slats that roll smoothly on precision bearings, locking in any position from fully open to completely closed.
Our flush-mount design sits just one inch above your truck bed rails, maintaining your vehicle's sleek profile while delivering maximum cargo protection. The sturdy aluminum construction stands up to highway speeds, harsh weather, and daily wear without adding excessive weight to your truck.
The X4S features our signature one-hand operation system that lets you open, close, or partially retract the cover without climbing into the bed. Whether you're hauling tall equipment or protecting valuable cargo, the Revolver X4S adapts to every job with professional-grade durability.
Revolver X4S specifications
Aluminum Slat Construction & Sealed Bearing System
We engineered the Revolver X4S with powder-coated aluminum slats that deliver exceptional strength without the weight penalty of steel alternatives. Each slat connects through a continuous hinge system that distributes stress evenly across the entire cover surface.
The sealed bearing mechanism runs the full length of both bed rails, ensuring smooth operation even after years of exposure to mud, dust, and road salt. Our precision-machined rollers glide effortlessly through their tracks, requiring minimal force to retract or deploy the cover in any weather condition.
Flush-Mount Installation & Bed Rail Integration
Our clamp-on mounting system installs inside your truck bed rails without drilling holes or permanent modifications to your vehicle. The X4S sits flush with the top of your bed rails, creating a streamlined appearance that preserves your truck’s original lines.
Installation Requirements
The cover fits most full-size truck beds from 5.5 to 8 feet in length, mounting directly to factory bed rail systems. We include all necessary hardware, adjustment shims, and detailed instructions for proper alignment with your specific truck model.
Locking Positions & Cargo Access Options
The BAKFlip Revolver X4S locks securely at the tailgate when fully closed, engaging dual automatic latches that prevent unauthorized access to your cargo. Our keyed locking mechanism operates independently from your truck’s central locking system for added security.
You can also lock the cover in any partially retracted position, allowing you to haul tall items near the cab while keeping the rear section of your bed protected and secured. This flexibility eliminates the need to fully remove the cover when transporting oversized cargo.

BAKFlip Revolver X4S Questions
Yes, the Revolver X4S supports evenly distributed loads up to 300 pounds when fully closed and latched. The aluminum slat construction creates a rigid surface that can handle snow accumulation, light equipment, or kayaks placed on top of the cover.
We recommend using protective padding under heavy items to prevent scratching the powder-coated finish. Avoid concentrated point loads that could dent individual slats.
The X4S provides excellent water resistance through overlapping slat design and integrated drainage channels. While no retractable tonneau cover is 100% waterproof, the X4S keeps the vast majority of water out during rain and automatic car washes.
The sealed bearing system and drain tubes channel moisture away from your cargo area. For maximum weather protection, we recommend avoiding high-pressure washes directly on the slat seams and ensuring your bed drain holes remain clear.
The Revolver X4S is compatible with spray-in bed liners and most drop-in liners that don't interfere with the bed rail mounting area. The clamps attach inside your bed rails, so the liner material doesn't affect installation.
If you have a thick drop-in liner with raised rails, you may need to use the included adjustment shims to ensure proper cover alignment. The mounting system accommodates bed rail variations up to 1/4 inch without requiring additional hardware.
Yes, we designed the X4S for straightforward DIY installation using common hand tools. Most truck owners complete the process in 30-45 minutes working alone.
The cover arrives pre-assembled with the canister and slats already integrated. You'll mount the rail clamps, position the cover assembly in your bed, adjust for proper alignment, and tighten the hardware following our detailed instructions. No drilling or permanent modifications to your truck are required.
The X4S features our premium aluminum slat construction with enhanced weather sealing and a low-profile flush-mount design. It sits just one inch above your bed rails compared to taller retractable covers.
The X4S also includes our upgraded sealed bearing system for smoother operation and longer service life. All Revolver models share the retractable canister design, but the X4S offers the best combination of durability, appearance, and weather protection in our retractable lineup.
The Revolver X4S can improve fuel efficiency by reducing aerodynamic drag compared to driving with an open bed. The low-profile design smooths airflow over your truck bed at highway speeds.
Actual fuel savings vary based on driving conditions, speed, and your specific truck model. Many customers report 1-2 MPG improvements during highway driving, though results depend on multiple factors including tire pressure, load weight, and driving habits.
We recommend cleaning the Revolver X4S with mild soap and water every few months to remove road grime and salt buildup. Wipe down the slats and side rails, then lubricate the bearing tracks with silicone spray to maintain smooth operation.
Inspect the drain tubes periodically to ensure they're not blocked by debris. The powder-coated aluminum requires no special treatment, but avoiding harsh chemicals or abrasive cleaners will preserve the finish. Check mounting clamp tightness annually to maintain proper cover alignment.
