My BAK Revolver X4s Journey

The excitement bubbled up as I unwrapped the BAK Revolver X4s Hard Rolling Truck Bed Tonneau Cover. As a proud owner of a 2023 Silverado, I’d spent significant time researching the perfect tonneau cover. But nothing prepared me for the real thing.

The Research Phase

My goals were clear:

  1. A bed that remained both secure and dry.
  2. Easy access to the full bed when needed.
  3. A durable metal construct over plastic or vinyl.

Electric retractable tops beckoned, but their high price tags made me rethink. Then, BAKFlip caught my eye. It seemed to offer the best of both worlds – the robustness of a metal retractable top without breaking the bank.

The Arrival

My heart skipped a beat as the delivery arrived. Some reviews had mentioned shipping damages, so I approached with trepidation. But the packaging was impeccable. So sturdy that my 17-year-old daughter managed to haul it into the garage, all by herself.

Installation Time

Spread out before me were the components – brackets, nuts, washers, lock washers. Separating the hardware and following a mix of online videos and manual instructions, I began. An hour flew by. The only challenge? Ensuring the brackets firmly grasped the bed rails. A few adjustments, a final tightening of bolts, and voila! My Silverado sported its new accessory with aplomb.


The first rains tested the cover’s mettle. To my delight, everything inside remained bone dry! Though some reviews warned of leaks, mine held firm. Of course, the dust did make its way in, but hey, that’s the way trucks work. Dust comes with the territory!

However, no product is without its quirks. The size seemed a tad off – about two inches shorter than ideal. This meant, when positioned towards the cab, the tailgate coverage wasn’t enough. When moved to favor the tailgate, the front wasn’t covered enough to keep out the water. While provided foam tape tried to fill this gap, it wasn’t wholly successful.

Still, was this a deal-breaker? Not for me. For the benefits it brought, these minor inconveniences paled.

The Verdict

The BAK Revolver X4s is a keeper. It marries form with function, all while saving a pretty penny. The remote control retractability of other models might sound fancy, but in the end, is it worth the added cost? I don’t think so. This cover’s robustness, aesthetic appeal, and functionality make it a worthy addition to any Silverado. And for anyone still on the fence about it, I say take the leap. You won’t regret it.

What is the BAK Revolver X4s Tonneau Cover?

The BAK Revolver X4s is a hard rolling retractable tonneau cover constructed from aluminum slats covered in a matte black finish. Representing the fourth generation in BAK’s Revolver tonneau line, the X4s features upgrades and improvements for enhanced security, weather protection, ease of use, and overall functionality.

As a hard tonneau cover, the Revolver X4s provides a durable barrier when closed, offering truck owners a high level of cargo protection, defense against theft, and shielding from weather elements. The “rolling cover” design means that it retracts by rolling up instead of folding or lifting open. This allows for fast, easy access to the bed without removing the cover.

The Significance of a High-Quality Truck Bed Cover

Investing in a high-end tonneau cover like the BAK Revolver X4s brings several advantages:

  • Enhanced cargo security – The hard cover construction and locking system deter theft of gear in the truck bed.
  • Weather protection – The cover shields cargo from rain, snow, wind, and other elements that can damage your belongings.
  • Improved MPG – Tonneau covers improve gas mileage by reducing aerodynamic drag.
  • Truck bed protection – The cover prevents rust and UV damage to the truck bed itself.
  • Aesthetic appeal – Tonneau covers enhance the look of the truck, especially stylish designs like the Revolver X4s.

For truck owners who rely on their pickup for work, recreation, or everyday transportation, a high-end cover is a smart investment – providing security, protection, and versatility. The Revolver X4s aims to deliver the ultimate package.

Design and Appearance

Part of what distinguishes the premium Revolver X4s is its design aesthetic. Upgrades to the look and construction result in a cover that makes a bold styling statement in addition to its functional benefits.

Matte-Black Finish: A Stylish Evolution in Truck Bed Covers

Previous generations of the Revolver featured a gloss black finish. With the X4s, BAK transitioned to a matte black powder coat on the aluminum slats. This gives the cover a sleek, low-glare appearance in line with contemporary automotive trends. The matte finish looks sharp on any truck, especially darker-colored models.

Low-Profile Design: Enhancing the Aesthetic of Your Truck

In designing the Revolver X4s, BAK lowered the cover’s profile compared to earlier Revolver models. The slimmed down proportions give it a curved, aerodynamic look that hugs the bed rails when closed. This better complements the truck’s factory dimensions.

Water-Tight Side Seal: Ensuring Protection Against the Elements

The Revolver X4s newly incorporated an integrated drip rail along the sides of the canister. This creates a water-tight seal that channels water away and prevents seepage into the truck bed from the side rails. Owners in wet climates have reported the cover providing outstanding weather resistance.

Functionality and Features

In addition to its stylish good looks, the BAK Revolver X4s delivers top-notch performance via an array of heavy-duty features and enhancements. These elements enable it to provide the ultimate blend of security, ease of use, and protection against the elements.

Premium Hard Rolling Cover: Offering Durability with Ease of Use

As a hard tonneau cover, the aluminum slat construction of the Revolver X4s offers the highest level of durability, dent resistance, and theft deterrence. The cover withstands years of use and elemental exposure while maintaining structural integrity. Unlike vinyl covers, it will not sag over time.

Despite the heavy-duty build, the segmented panels and rolling retraction make opening and closing the cover an easy, one-person operation – no need for folding or removing bulky panels. Owners enjoy the best of both worlds.

Rotational Locking System: An Advanced Security Feature

The Revolver X4s employs an upgraded locking system not found on earlier Revolver models. It uses rotational latches on the rear panel that clamp down on the cover from both sides when locked. This applies even pressure and enhances security. The keys are double-sided for convenience.

Smooth Forward Roll: Easy Access to the Truck Bed

The smooth, no-bind rolling retraction system makes opening and closing the Revolver X4s effortless. Just flip the latches up, grab the release handle integrated into the rear panel, and the cover gently rolls forward for full-length bed access. The gas shocks allow easy operation from either side of the truck.

Integrated Bulkhead Seal: Boosting Weather Resistance

Where the cover meets the truck’s bulkhead, the Revolver X4s now features a tight-fitting seal that hugs the contours of the front bed wall. This creates a water-tight barrier at the bulkhead, further enhancing rain and snow runoff while helping maintain dryness in the bed interior.

Redesigned Rear Corner Caps: Ensuring Optimal Fit and Function

The rear corner caps were redesigned on the X4s for better aesthetics, fit, and coverage. The low-profile corners provide a smooth transition along the bed rails for optimal function. Owners report the cover aligns cleanly with the contours of the truck bed.

In all, the coverage, seals, locking system and premium materials make the Revolver X4s one of the most protective and secure covers available from BAK Industries. It provides worry-free cargo protection for truck owners needing maximum security.

Installation and Use

One of the common concerns truck owners voice about tonneau covers is difficulty with installation and use. Does the Revolver X4s live up to its promise of quick, simple DIY installation and effortless operation? Here’s a closer look.

Ease of Installation: A Guide to Setting Up the BAK Revolver X4s

One of the most frequent compliments made about the Revolver X4s is how easily it can be installed by the DIY truck owner – usually in an hour or less. The process involves:

  • Carefully unpacking the components and organizing the rails, canister panels, clamps, and weather strips.
  • Positioning the canister in the truck bed and securing to the side rails with C-clamps.
  • Attaching the provided side rail adapters using the integrated clamps.
  • Setting the assembled canister cover into the rail adapters and clamping firmly in place.
  • Checking that the cover retracts properly before tightening everything down securely.

With the detailed installation instructions BAK provides, most truck owners find they can have the X4s installed without issue using basic hand tools. No drilling is required. The adapters ensure customized fit.

Usage Tips: Getting the Most Out of Your Tonneau Cover

To properly operate the Revolver X4s:

  • Be sure to fully engage the rotational lock latches on each side when securing the cover.
  • Do not drive with the cover partially open. Either fully close and lock it or retract it all the way forward.
  • Periodically lubricate the latch mechanisms with silicone spray to maintain smooth opening and closure.
  • When closing the cover, gently drop the rear panel before pressing down firmly to engage the locks fully.
  • Keep it clean! Rinse the cover occasionally with water and wipe down with a quality UV protectant to minimize staining.

Following these simple usage tips will keep your cover functioning optimally for years while looking its best.

Safety Features: Ensuring Your Cargo is Protected and Secure

  • The heavy aluminum panels are dent and drill resistant to prevent cargo tampering.
  • The full-length weather stripping creates a tight seal along the length and front of the bed interior when locked.
  • The pull strap provides a way to safely retract the cover from the side of the truck instead of climbing into the bed.
  • The integrated locking system uses latch mechanisms on both sides for balanced, secure clamping.
  • Rear corner caps eliminate gaps that could allow prying tools to enter when locked.

Reviews and Feedback

With the Revolver X4s being a newer model, online reviews and owner feedback are still limited at this point. However, initial responses indicate very positive experiences with the cover’s performance, construction, appearance, and value.

Customer Experiences: What Users are Saying About the BAK Revolver X4s
