The #1 Best-Selling Hard Folding Bed Cover — Now for GM’s Electric Trucks

If you own a 2024 Chevrolet Silverado EV, 2025 Chevrolet Silverado EV, 2026 Chevrolet Silverado EV, 2024 GMC Sierra EV, 2025 GMC Sierra EV, or 2026 GMC Sierra EV, and you want maximum cargo security without sacrificing clean factory styling, the BAKFlip MX4 (Part #448147) is one of the strongest options available.

The MX4 has earned its reputation as the #1 best-selling hard folding tonneau cover in North America — and this application is engineered specifically for the 6ft bed EV platform.

This is not a gas Silverado adaptation.
This is tailored to the GM electric truck chassis.


Designed Specifically for 2024–2026 Silverado EV & Sierra EV (6ft Bed)

Compatible with:

  • 2024 Silverado EV 6ft Bed

  • 2025 Silverado EV 6ft Bed

  • 2026 Silverado EV 6ft Bed

  • 2024 Sierra EV 6ft Bed

  • 2025 Sierra EV 6ft Bed

  • 2026 Sierra EV 6ft Bed

Compatible with or without Multi-Flex / Midgate configurations.

Important:

  • Does NOT offer full bed access

  • Does NOT include prop rods

  • Cannot fold vertically against rear glass

  • Provides 2/3 bed access

This is critical for proper buyer expectation and reducing returns.


Heavy-Duty Aluminum Panels Built for Real-World Use

The BAKFlip MX4 is built using:

  • Heavy-duty aluminum panels

  • Premium high-density foam core

  • Advanced matte black finish

This construction delivers:

  • Strength without excessive weight

  • Rated up to 400 lbs evenly distributed load

  • Superior dent resistance

  • Enhanced rigidity

For EV truck owners carrying tools, gear, or high-value cargo, this level of structural integrity matters.


Advanced Matte Finish — Built to Resist Scratches & UV Damage

The MX4’s premium matte finish is:

  • UV-resistant

  • Scratch-resistant

  • Scuff-resistant

  • Fade-resistant

This is especially important for 2024–2026 Silverado EV and Sierra EV owners, as the flush-mounted design makes the cover highly visible.

The finish maintains a clean, factory-style appearance for years.


Flush-Mounted Low-Profile Design

The MX4 mounts inside the bed rails and sits flush with the top of the bed.

Benefits:

  • Clean OEM look

  • Improved aerodynamics

  • Reduced wind noise

  • Seamless EV styling

If you're searching for a low-profile hard tonneau cover for Silverado EV or Sierra EV, the MX4 checks every box.


Secure Auto-Latching System

Security is where the MX4 stands apart.

Features include:

  • Injection-molded latch housings

  • Secure auto-latching panels

  • Tailgate-activated locking

Once the tailgate is closed, the panels lock automatically — protecting your cargo inside the bed of your 2024–2026 EV truck.

The dual-action tailgate seal allows operation whether the tailgate is up or down.


All-Season Weather Protection

The MX4 is engineered to perform in extreme climates.

Equipped with:

  • Durable perimeter rubber seals

  • Integrated tailgate seal

  • Water-resistant panel joints

Whether you’re driving a 2024 Silverado EV through heavy rain or a 2026 Sierra EV in harsh winter conditions, the MX4 is built to protect your cargo.


Flexible Operation for Everyday Use

The MX4 allows:

  • Driving fully closed

  • Driving with panels folded and secured

  • Quick panel folding for partial bed access

While it does not provide vertical full-bed access, it offers strong daily usability for work and lifestyle builds.


Built for EV Owners Who Expect Premium Quality

GM EV trucks represent a new era of truck ownership — modern, premium, and technology-forward.

The BAKFlip MX4 matches that level with:

  • Refined operation

  • Durable construction

  • Sleek styling

  • Long-term reliability

It’s a premium solution for premium trucks.


Extended 5-Year Warranty

The MX4 for 2024–2026 Silverado EV and Sierra EV is backed by:

  • Extended 5-Year Warranty

  • RealTruck expert support

Proudly assembled in Missouri.
