BAK Revolver X4s Overview
The BAK Revolver X4s is a premium hard roll-up tonneau cover that delivers strength, style, and convenience. Constructed with durable interlocking aluminum slats overlaid with marine-grade vinyl, it offers rugged protection with a sleek, leather-grained finish.
Its matte black slats, clamps, and hardware, combined with flat side seals and redesigned rear corner caps, give it a smooth, low-profile look. The patented rotational locking rails secure the cover along the entire length of the bed, ensuring maximum security against unauthorized access.
Designed for versatility, the X4s provides full bed access when fully rolled to the bulkhead and includes durable safety straps and buckles to secure it when open.

The easy-to-use latch mechanism and integrated bulkhead seal offer superior weather protection. With a 400-lb. weight capacity (evenly distributed) and compatibility with most 5th-wheel hitches, it’s as functional as it is durable.
Installing the X4s is simple with its no-drill, clamp-on system, and it keeps stake hole pockets exposed for accessory use.
Backed by a 5-year warranty and proudly made in the USA, the BAK Revolver X4s is the ideal choice for truck bed protection with added style and high-level functionality.
BAK Revolver X4s Maintenance Tips
You can easily maintain the BAK Revolver X4s by cleaning it with soap and water and protecting the vinyl with 303 Aerospace Protectant (avoid Armor All). I suggest regularly checking the clamps, bolts, and latches to keep them secure and lubricated.
Make sure to remove snow, ice, or debris before opening the cover, and avoid placing items on it to prevent damage.
Is BAK Revolver X4s Made in USA?
Yes, the BAK Revolver X4s is proudly made in Springfield, Missouri, ensuring high-quality craftsmanship.
Can You Lock It Half Way?
No, the cover cannot be locked/strapped halfway. It must either be fully closed and latched on both sides or fully rolled up and securely strapped at the cab.
Is It Waterproof?
While not fully waterproof, the BAK Revolver X4s provides excellent water resistance, with heavy-duty seals minimizing leaks. Small drips may occur at the tailgate corners during heavy rain.
How Secure and Reliable Is It?
It is highly secure thanks to patented rotational locking rails and slam latches, which protect against prying, cutting, or unauthorized access when the tailgate is locked. Its durable materials further ensure long-term reliability.
