BAKFlip MX4 TS 250 | Tri-Fold Tonneau Cover with Sealed Bed Storage
Our BAKFlip MX4 TS 250 delivers the legendary durability of our MX4 tonneau cover with the versatility of our integrated TrackSystem. This tri-fold hard cover features heavy-duty aluminum panels with a matte finish that resists scratches, UV damage, and extreme weather while maintaining a low-profile stance on your truck bed.
The TS 250 model includes two full-length aluminum rails mounted to the tonneau underside, creating a secure track for compatible cleats, tie-downs, and cargo management accessories. We engineered this system to give you organized storage without drilling into your truck bed, preserving resale value while maximizing utility.
Whether you’re securing tools, sporting equipment, or everyday cargo, the MX4 TS 250 adapts to your needs. The cover folds completely open for full bed access, partially open for tall cargo, or locks closed to protect valuables from weather and theft.
What makes the MX4 TS 250 different

TrackSystem Integration & Cargo Management
The 250 series TrackSystem transforms your tonneau cover into a complete cargo management solution. We machine two extruded aluminum rails directly into the underside of the cover panels, running the full length of your truck bed. These rails accept our BAKBox 2 toolbox, sliding tie-down cleats, and adjustable cargo dividers.
Unlike aftermarket track systems that require drilling through your bed liner, our integrated approach keeps your truck bed intact. The rails sit above the bed surface when the cover is closed, so you can slide accessories anywhere along the 250 track length without removing the tonneau. When you need full bed access, fold the cover completely open and your TrackSystem accessories fold with it.

Panel Construction & Weather Protection
We build every MX4 TS 250 panel from aircraft-grade aluminum with a powder-coated matte finish that resists rust, corrosion, and industrial chemicals. The tri-fold design uses three equal-length panels connected by our reinforced hinge system, engineered to withstand years of daily operation in harsh climates.
Sealed Bed Technology
Our exclusive weather seal system creates a sealed bed environment that protects cargo from rain, snow, and road spray. We install continuous EPDM rubber seals at every panel junction and along all four bed rail contact points. The automatic slam latch system pulls panels tight against these seals, eliminating water intrusion even in heavy weather.
Installation & Truck Compatibility
The MX4 TS 250 installs in approximately 30 minutes using only basic hand tools. Our clamp assembly system secures to your truck’s existing stake pocket holes without drilling, cutting, or permanent modifications. We include all mounting hardware, rail assemblies, and a detailed instruction guide with every cover.
Most full-size truck models from 2015-present accept the 250 configuration. We manufacture covers for 5’7″, 6’5″, and 8′ bed lengths across Ford, Chevrolet, GMC, Ram, Toyota, and Nissan platforms. Our online fit guide confirms exact compatibility for your year, make, model, and bed length.

BAKFlip MX4 TS 250 Questions
The 250 refers to our TrackSystem rail configuration with two full-length aluminum tracks integrated into the tonneau cover underside. These rails run the complete length of your truck bed and accept all BAKFlip TrackSystem accessories including tie-down cleats, cargo dividers, and our BAKBox 2 toolbox. The system allows you to organize and secure cargo without drilling into your truck bed.
Yes, the MX4 TS 250 installs over most spray-in bed liners without issues. Our clamp assembly system secures to your truck’s stake pocket holes and sits on top of the bed rails, so liner thickness doesn’t affect installation. The cover maintains proper weather seal contact with the rails regardless of liner type. We do recommend checking our fit guide to confirm compatibility with your specific truck model and bed liner combination.
Absolutely. When you fold the rear panel or front panels open, your TrackSystem rails and any mounted accessories fold with the cover sections. This means your tie-down cleats, dividers, or BAKBox stay accessible regardless of cover position. You can secure tall cargo with the rear panel folded while still using the TrackSystem on the closed front panels for organizing smaller items.
Each TrackSystem rail is rated for 50 lbs per mounting cleat when accessories are properly installed. We recommend distributing heavy loads across multiple tie-down points spaced 12-18 inches apart for optimal strength. The closed tonneau panels themselves support up to 400 lbs of evenly distributed snow load, but this rating is separate from the TrackSystem accessory capacity.
No drilling required. Our clamp assembly system uses your truck’s existing stake pocket holes to secure the cover. Installation takes about 30 minutes with basic hand tools and leaves your truck bed completely unmodified. This no-drill approach preserves your truck’s resale value while providing rock-solid tonneau cover stability. All necessary mounting hardware ships with your cover.
Yes, the MX4 TS 250 is compatible with most fifth-wheel and gooseneck hitch systems. When you need to tow, simply fold the front tonneau panel forward to provide complete clearance for your hitch and trailer kingpin. The tri-fold design allows the cover to rest against the cab while maintaining weather protection for the rear 2/3 of your bed. Check our fit guide for specific compatibility with your hitch model.
The 250 TrackSystem accepts our complete line of cargo management accessories including the BAKBox 2 sliding toolbox, adjustable tie-down cleats, cargo dividers, and anchor points. All accessories mount by sliding into the aluminum rails and locking in place with integrated clamps. You can mix and match accessories based on your hauling needs and reposition them anywhere along the track length without tools.
