10 Years of Testing. Tonneau Cover Compatible. Integrated Side-Access Storage.
The World's Most Advanced Tonneau-Integrated RackThe Leitner Designs ACS ROOF for Tonneau Covers is the culmination of 10 years and hundreds of thousands of off-road miles of testing. We took the DNA of our legendary Active Cargo System (ACS) and adapted it for truck owners who want to keep their bed covered while maximizing overhead storage.
Proudly over-engineered and over-built in Corona, California, this low-platform rack is designed to help you "Carry Your World." It is stronger than the competition, easier to assemble, and features the industry-first side-opening GearPOD ROOF for instant access to your equipment.
The Problem & The Solution:The Pain: Most truck owners feel they have to choose between a tonneau cover and a functional rack. Existing racks are often difficult to install alongside covers, lack adjustability, and make it nearly impossible to reach gear without climbing onto the truck.
The ACS Solution: This version of the ACS ROOF integrates directly with your tonneau mounting hardware, offers Infinitely Adjustable Load Bars, and provides side-access storage so you never have to step on your tire to grab a recovery strap again.
Key Features: ACS ROOF for Tonneau Covers
Designed to work seamlessly with T-slot integrated tonneau covers. It mounts using the cover's existing hardware for a clean, secure fit.
The industry-first GearPOD ROOF (optional) allows you to store 100 lbs of gear with side-opening access—no more reaching over the bed.
Sliding load bars in toothed channels let you mount your rooftop tent, bikes, or kayaks exactly where you want them, not where the rack dictates.
Keeps your center of gravity low and wind noise down while maintaining enough clearance for your tonneau cover to operate.
Engineered for simplicity. Our precision-fit components ensure a world-class assembly experience without the typical aftermarket headache.
Manufactured in Corona, CA, using heavy-duty aluminum alloy and multi-wall thickness extrusions for maximum rigidity.
Uses black Zi-Ni coated Grade 10.9 fasteners with Loctite to ensure your rack stays silent and secure on long highway drives.
Compatible with T-track mounting accessories from Thule, Rhino-Rack, and Yakima for endless gear mounting options.
Superior Extrusion TechnologyWe don't use standard generic bars. The ACS ROOF features custom multi-slot profile extrusions designed specifically for load distribution and accessory integration. This over-engineered approach ensures that your platform won't flex or sag over time.

"Finding a rack that plays nice with my Retrax tonneau cover was a nightmare until I found this. The ACS Roof for Tonneau is incredibly rigid. Having the side-opening GearPOD means I can grab my air compressor without peeling back my cover or climbing into the bed. It's the perfect setup for someone who uses their truck for both work and play."
- David K., Truck Owner & Weekend Warrior Important Load & Use NoteNote: Because this rack is secured to the truck via the mounting hardware of your tonneau cover, we cannot recommend a safe off-road weight limit. Always follow your tonneau manufacturer's recommended weight limits for their mounting rails.

Off-road travel subjects the mounting points to extreme vibratory forces. Since this rack mounts to the T-slots of a tonneau cover rather than directly to the truck frame or bed, the weight limit is dictated by the strength of the tonneau manufacturer's rails. We recommend adhering to on-road limits for maximum safety.
The ACS ROOF for Tonneau is designed to work with most retractable and hard-folding covers that feature an integrated T-slot track system (like those from Retrax, Pace Edwards, or Yakima). Ensure your cover has top-facing tracks before ordering.
Yes. This rack is designed as a low-platform system that sits above the bed line. However, the exact clearance for folding or rolling your cover depends on your specific cover model. Most retractable covers operate with zero interference.
The side-opening GearPOD ROOF is automotive-grade sealed and designed to keep out rain, snow, and trail dust. While it is highly weather-resistant, it is not submersible. We recommend sensitive electronics be kept in dry bags during extreme storm conditions.

Prop 65 Warning- Product may contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov
Proposition 65 is a California law passed in 1986. Its goals are to protect drinking water sources from toxic substances that may cause cancer and birth defects and to reduce or eliminate exposures to those chemicals generally, for example in consumer products, by requiring warnings in advance of those exposures.
The regulation requires the State of California to revise and republish yearly a list of chemicals known to the State of California to cause cancer or birth defects or other reproductive harm. The current list contains over 900 naturally occurring and synthetic chemicals. This regulation also requires manufacturers to place warnings on products that contain any of the chemicals listed by the State of California. No other states require warnings of this nature, and products with Prop 65 warning language are legal to sell in all states. Detailed information regarding requirements for compliance to the California Prop. 65 is can be found at: www.P65Warning.ca.gov

The wait time was more than I anticipated even after seeing the notification of long lead times. I have to give them props for giving some compensation for the excessive wait time. Having slightly larger holes would help with fitment. Had a hard time getting the front drivers side away from the pinch weld. Eventually had to use washers to add space away from the truck. Need to update pictures and instalation video for the new sliders they are now making
All packing and shipment were great, everything was there. I had to contract out the install because of arthritis, it took them two hours and looks perfect. Zero wind noise at any speed 0 to 100.
Absolutely love my new rack and roam cases. Appreciate the Sherpa crew as well for their hospitality while the installation was taking place.
Fit and finish is excellent. Looks great on the Bronco. No whistling noise at all, some additional wind noise over 60mph but not much different than it was without the rack. Assembly was not too difficult. Instructions and videos could be a little better.
The quality and dedication of the team at Sherpa is evident from the very first interaction with them, and is further proven in the product itself. This rack is well engineered, easy to assemble, easy to adjust, and holds up incredibly well with no loosening or rattling or shifting (even after over 200 miles of driving on poorly maintained roads). Currently operating with approximately 180 pounds of gear mounted on the bed rack and no issues at all so far. I expected the vibration to work the bolts loose over time, but every time I check they're all still snug. My only regret is that I didn't pull the trigger and get this rack sooner.
First of all, the team at Sherpa is full of passion for adventure and that passion shows in the quality of their products. This roof rack looks incredible and surprised me with it's sturdiness. No loosening of hardware, even after weeks of driving. Currently holding approximately 80 pounds of gear for everyday driving, plus an additional 110 strapped on top during a camping trip (and I even stood on top of the entire loadout). No warping, bending, twisting, or slipping. The fact that this matches the bed rack perfectly in height is the icing on the cake. Easily serves as a tie off for a tarp, rain fly, hammock, or whatever you need. Perfect for modular campsite setup and quick teardown.
I bought the Sherpa Crestone rack for my 2024 4Runner TRD Pro. Incredibly well-made and excellent design. Spend the extra , to get best roof rack in the market. You won’t regret it.
This is our first roof rack that we are going to use to put a RRT (roof top tent) on for back country trips. Well-built product that came with all the nuts, bolts and washers to complete the installation. Took about 1-1/2 to 2 hours install the rack. You will another person to help place the racks on top of the Jeep for final install. Overall, a great, well-built American product
Install was super easy. The quality was great. Customer service was quick to respond to any issues! I’ve already been getting compliments on it and what brand it is. This will be great for camping this year!
This is on my tundra absolutely solid rack looks fantastic extremely modular, which is why I went this route. I can use the whole rack when traveling and over landing then rock the chase rack only when the rest is not in use, I actually use the recovery traction board mounts for my shower room set up, which works amazingly just relocated the board somewhere shown in picture keep innovating TUWAand I’ll keep purchasing.
Good looking cat shields made of stainless steel with cooling holes. Priced well, easy install, no issues. Would buy again.
Great service from their staff. Robert help me through all the process with a request I had, he responded all emails in a timely manner and provided great help.
We received it within 3 days and installed the same day. Great awning and very well made.
the tent is very nice, comfortable and roomy.
Following the instructions was fairly easy. Its better to have second person to set it up. I really like the tent and the support that from ExtrailAuto. Really recommeded! Thanks
