Bak Industries BakFlip MX4 Tonneau Cover for Silverado Sierra 1500 with 5'8" Bed PART NUMBER: 448130
BRAND: Bak Industries DESCRIPTION BakFlip MX4 Gen 3 Hard Folding Tonneau Cover
The best-selling truck bed cover in the world just got better.
Introducing the new and improved RealTruck BAKFlip MX4 (GEN3 Model Year 2025) - an evolution of RealTrucks most popular tonneau cover. This next-generation upgrade builds on everything truck owners already love about MX4, now enhanced with improved functionality, greater durability, and elevated security.
The new and improved BAKFlip MX4 is constructed primarily from alloy materials, including heavy-duty aluminum top panels and side rails. Reinforced with high-density polymer cores, each panel delivers a 22 percent increase in overall strength compared to the original model.
Security is also enhanced. In addition to BAKs patented auto-latching system, which automatically secures the cover when closed, the BAKFlip MX4 (GEN3) features re-engineered lock components for improved resistance to forced entry compared to the GEN2. No matter the cargo youre transporting, you can rest assured knowing your gears protected.
When the weather turns, the BAKFlip MX4 (GEN3) holds strong. Revised EPDM rubber perimeter seals and tight-fit clamps provide their best seal yet, preventing seepage between the bed cover and bed rails. At the rear of the cover, a 13 percent longer dual-action tailgate seal provides weather protection for the tailgate.
The BAKFlip MX4 isnt only durable, its also sleek and stylish. Unlike competitors, the BAKFlip MX4 sits flush with your pickups bed rails, practically disappearing into your trucks profile. And with a sleek, textured matte black finish across all surfaces, the MX4 looks great whether open or closed.
Installation is streamlined thanks to an improved click-in mounting system, reducing setup time by 12 percent. Operating the cover is just as simple - drop the tailgate, release the rear latch mechanism, and fold the cover toward the bulkhead. If full bed access is required, fold the cover flush against the rear window - third brake light visibility remains unobstructed in any position.
THE ORIGINAL. OFTEN IMITATED. NEVER DUPLICATED. MX4 defined the hard folding category - and still sets the benchmark with patented features, premium materials, and a proven design built to perform.
BEST-IN-CLASS AUTOMATIC SECURITY. COMES STANDARD.The patented auto-latch system engages immediately on closure - no separate locking action required - so your gear is locked down the moment it closes.
SEALED EDGE-TO-EDGE. TO KEEP WEATHER OUT. Advanced seals and precision-fit clamps create a tight, edge-to-edge barrier to block out the elements and keep your cargo dry.
BUILT STRONGER. BUILT BETTER. BUILT TO LAST. Premium-grade, multi-layer aluminum construction over a high-density core delivers a stronger, more durable surface thats tested for years of reliable durability. Don't settle for single-layer construction that bends under pressure.
