Best quality, tightest sealing hard fold up cover available

I researched for several weeks all the competing covers and styles. Previously had a vinyl roller cover I was satisfied with, however I wanted something more secure on my next truck.

I watched several YouTube reviews of the AL4 and competing brands and really liked the features of this aluminum cover, the double weather strip on the sides to keep out water, and the ease of installation with the side rails. Also has six locking points along the edges and can stand upright allowing almost full use of the bed if needed.

The price from sharptruck.com couldn't be beat, and free shipping which I received overnight, with excellent packaging from the factory. Completely satisfied customer!

Spent several weeks researching the various hard flip-up tonneau covers, and finally settled on the AL4. No one has a better price than SharpTruck, and it arrived quickly. The cover itself is solid and well built, and was securely packaged. The installation was fairly straightforward, although I have a drop-in bedliner, and that created a few issues. There is some leakage, but they all do and it's minimal enough that I haven't taken the time to address it yet. I'm sure I'll be able to eliminate most, if not all of it. It's a heavy duty cover, and whatever they used for a finish looks like a million bucks. It looks great on my truck and I'm very happy with my purchase. Thanks, SharpTruck !

I have owned 3 covers for different trucks. This is by far the best cover I have had. It is very well built and was easy to install.

I pulled the trigger on the Worksport AL4 after having 2nd thoughts due to the mixed reviews on the BAK MX4.  So glad I went with the AL4 - the installation was a breeze and the look is more aggressive than the others. The matte finish and rugged look works great with my 2025 Ram Rebel X.  Its only rained heavy once since I installed it a couple of weeks ago and though there was water intrusion it was relatively minor; it ran down the bulkhead and tailgate area.  The bulkhead can be further adjusted (haven't gotten around to it as it was not a big deal to me) and I can't blame the cover on the tailgate water as its a Ram design issue (gaps are too wide).  Overall two weeks in, I'm very happy with the AL4 and only time will tell...

Please confirm this is the new upgrade worksport has been advertising coming finally in 2025.

Do you have one that will fit the Carbon Pro bed? Would prefer the AL4 but would look at others as well.

Here is a Westin cover that WILL work with the CarbonPro bed, www.sharptruck.com/westin-19-43995-hard-tri-fold-tonneau-cover

Premium Strength, Security, and Weather Protection

The WorkSport AL4 Hard Tri-Fold Cover is built for truck owners who demand maximum security, weather protection, and ease of use. With its ultra-durable, 3x thicker aluminum panels and DiamondSHIELD finish, this hard tonneau cover is designed to withstand up to 400 lbs of evenly distributed weight while maintaining a sleek, low-profile appearance. Whether you're hauling work equipment or outdoor gear, the AL4 is engineered to provide fast access to your cargo while keeping it protected from the elements. Proudly made in the USA, the AL4 Hard Tri-Fold Cover is designed to fit your specific truck model and installs in under 45 minutes with no cutting, drilling, or modifications required.

Built to Last – Heavy-Duty Construction

The WorkSport AL4 is not your average hard tonneau cover. Its formed aluminum panels are up to 4x thicker than many competing covers, ensuring exceptional strength and durability. This robust design is reinforced with a crossbar to maintain structural integrity while keeping the cover lightweight for easy handling.

The DiamondSHIELD finish adds an extra layer of scratch resistance while providing a clean, modern look that enhances your truck’s appearance.

Quick and Effortless Bed Access

The tri-fold design of the AL4 allows for easy and fast access to your truck bed. Need full bed access? Simply flip it up, and you're ready to load oversized cargo without removing the cover. Whether you're packing up for a trip, making a supply run, or dealing with unpredictable weather, the cable-operated Quick Latches make opening and closing the cover effortless and secure.

Weatherproof Sealing to Keep Cargo Dry

Rain, snow, and debris won’t stand a chance. The WorkSport AL4 features specially formulated EPDM weather-resistant seals, along with closed-cell foam corner caps and gap seals, to completely block out water instead of just redirecting it. Unlike other covers that allow moisture to seep in at panel joints, the AL4’s seamless, single-formed aluminum panel design eliminates potential leak points, ensuring that your cargo stays dry and protected in all conditions.

Enhanced Security & Latch System

The AL4 is designed with four secure latch points that easily slide across the crossmembers, ensuring a tight, locked-in fit. This extra security makes it more difficult for thieves to tamper with your cargo, giving you peace of mind whether you're parked at work or off-roading in remote locations.

Key Features

  • Heavy-Duty Aluminum Panels – Up to 4x thicker than standard tonneau covers for superior strength and durability.
  • Weather-Resistant EPDM Seals – Prevents water from seeping in, keeping your truck bed dry in all conditions.
  • Fast Cargo Access – Quick-release cable-operated latches for effortless opening and closing.
  • Full Bed Access – Folds up completely without removal, providing unrestricted access to your truck bed.

Seamless Installation – No Drilling Required

Installing the WorkSport AL4 is fast and hassle-free. No need for cutting, drilling, or trimming—each cover comes with model-specific brackets and all necessary hardware for a lightning-fast setup in under 45 minutes.

Care & Maintenance

Maintaining your AL4 Hard Tri-Fold Cover is easy:

  • Wash regularly with mild automotive soap and water to remove dirt and debris.
  • Avoid abrasive cleaners that could scratch the DiamondSHIELD finish.
  • Apply UV protectant (such as 303 Aerospace Protectant) to keep the painted aluminum surface looking like new.
  • Inspect the seals periodically and clean them with mild soap and water to maintain their waterproofing capabilities.
