BAKFlip CS Tonneau Cover & Rack System
The BAKFlip CS is our first integrated cover and rack system, engineered for truck owners who need both bed protection and cargo hauling capability. This hard folding tonneau cover features an aluminum rack structure permanently mounted to the cover panels, delivering 500 pounds of load capacity while maintaining the security and weather sealing of a premium folding cover.
We designed the CS for versatility — fold it open to access your full bed, close it for lockable storage, or load gear on top without removing the cover. The anodized aluminum rack bars sit 3 inches above the panel surface and run the full length of the cover, creating a stable platform for kayaks, lumber, camping gear, or rooftop cargo boxes. Our matte black powder-coated finish matches modern truck styling while resisting corrosion in all climates.
The system installs using our proven clamp-on rail design with no drilling required. Premium EPDM seals keep water out at highway speeds, and our reinforced aluminum panels resist dents from hail or impacts. When you need bed access, the cover folds completely against the cab in seconds, and the integrated rack design means you never sacrifice hauling capacity for security.
- Integrated aluminum rack structure with 500-lb dynamic load capacity
- Hard folding design with four reinforced aluminum panels
- Anodized rack bars positioned 3 inches above cover surface
- Premium EPDM rubber seals for complete weather protection
- Tool-free clamp installation — no drilling into truck bed rails
Rack Structure & Load Capacity
The CS rack system uses two full-length aluminum crossbars permanently bonded to the cover’s top surface, creating a unified structure that distributes weight across all four panels. Each crossbar measures 1.5 inches in diameter and features an anodized finish that resists scratches when loading cargo.
We rate the rack at 500 pounds dynamic load capacity when the cover is fully closed and latched. This capacity accommodates most rooftop cargo boxes, two full-size kayaks, bundled lumber up to 12 feet, or expedition gear for overlanding trips. The bars sit 3 inches above the panel surface to provide clearance for tie-down straps and create airflow beneath cargo.
Cover Panel Construction & Weather Sealing
We build the CS using the same reinforced aluminum panels found in our BAKFlip MX4, with additional structural bracing to support the integrated rack load. Each panel measures approximately 5/8 inch thick and features a closed-cell foam core that provides insulation and impact resistance.
The matte black powder coat finish is applied after fabrication and baked at high temperature for maximum adhesion. This surface resists fading from UV exposure and won’t show fingerprints or water spots like gloss finishes. Automatic tension adjusters at each hinge point keep the panels aligned as you fold the cover, maintaining consistent seal contact along all edges.
Installation Process & Truck Compatibility
The BAKFlip CS installs using our clamp-on side rail system that requires no drilling or permanent modifications to your truck bed. We include all mounting hardware and illustrated instructions with every system, and most customers complete installation in 30-45 minutes using basic hand tools.
You’ll mount the side rails to your bed using adjustable clamps that fit inside the stake pocket channels. Once the rails are positioned, the cover assembly drops into place and secures with quick-release pins. Final adjustments ensure the panels sit flush with your bed rails and the rack bars align parallel to your truck’s centerline.

Common Questions About the BAKFlip CS System
The CS rack system is rated for 500 pounds of dynamic load capacity when the cover is fully closed and latched. This rating applies to evenly distributed cargo secured with proper tie-downs. The load capacity assumes you’re driving at normal highway speeds and the cargo is properly secured to the anodized aluminum crossbars.
Exceeding 500 pounds or loading cargo unevenly can stress the hinge assemblies and void the warranty. Always distribute weight across both crossbars and use multiple tie-down points for longer items.
Yes, the CS rack is fully compatible with most rooftop tents, cargo boxes, and crossbar-mounted accessories designed for square or round bars. The anodized aluminum crossbars measure 1.5 inches in diameter and will accept mounting clamps from Thule, Yakima, and similar systems.
For rooftop tents, verify your specific tent model weighs less than 500 pounds when occupied and includes its own mounting hardware. Most hardshell RTTs under 200 pounds work perfectly on the CS. Cargo boxes should be secured using the mounting points built into the rack structure.
The CS installs using the same clamp-on rail system as our other <a href=”/hard-folding-tonneau-covers/”>hard folding tonneau covers</a>, with no drilling required. The main difference is the added weight of the integrated rack structure, which means you’ll want a second person to help position the cover assembly onto the side rails during installation.
Most customers complete installation in 30-45 minutes using basic hand tools. The system includes detailed instructions, all mounting hardware, and adjustment guides to ensure proper fit. Once the side rails are clamped to your bed, the cover drops into place and secures with quick-release pins.
No, the rack structure is permanently integrated into the cover panels and moves with them as you fold. The aluminum crossbars remain parallel to your truck bed in all positions — closed, partially open, or fully folded against the cab.
The added weight of the rack does make the cover slightly heavier to lift compared to a standard BAKFlip, but the dual-action hinges are engineered to handle this load. You’ll notice the weight difference most when folding all four panels open at once, but it’s still a one-person operation.
The CS uses the same premium EPDM rubber sealing system as our standard covers, providing weather-resistant protection for your truck bed. Water will not enter through the side rails or front header when the cover is properly latched and maintained.
Like all tonneau covers, the CS is weather-resistant rather than completely waterproof. Heavy rain or pressure washing may allow minimal moisture intrusion at the tailgate seal or drain channels. The design includes drainage paths that channel water away from the bed interior, keeping your cargo dry in normal driving conditions.
No, you must remove all cargo from the rack before folding the cover open. The rack structure is designed to support 500 pounds only when the cover is fully closed and latched in the horizontal position.
Attempting to fold the cover with cargo loaded will stress the hinge assemblies beyond their design limits and can cause permanent damage. Always unload the rack completely before opening any panel sections for bed access.
Wash the cover and rack monthly using car wash soap and a soft brush to remove road salt, dirt, and debris. Avoid pressure washing directly at the seal edges, and never use abrasive cleaners on the powder-coated aluminum finish.
Lubricate the hinge pivot points twice per year with silicone spray to maintain smooth operation under the rack’s added weight. Inspect the side rail clamps every few months to ensure they remain tight, especially if you regularly load heavy cargo on the rack. The anodized crossbars require no special maintenance beyond routine cleaning.
