Billet Aluminum Mounting. Roll Cage Strength. Safari Window Compatible.
Extreme Load Capability for the QuartermasterThe Leitner Designs ACS ROOF is the result of 10 years of engineering and hundreds of thousands of off-road miles of testing our legendary Active Cargo System (ACS). We took that DNA and created a world-class platform rack specifically for the INEOS Quartermaster.
Over-engineered in Corona, California, this rack features 6063 T6 aluminum extrusions and billet machined 6061 T6 aluminum brackets. It is designed to "Carry Your World" by bolting directly to the vehicle's roll cage points, creating a mounting system far stronger than the competition.
The Problem & The Solution:The Pain: Most racks rely on the factory rain gutters, which limit load capacity. Plus, high-profile racks often block Safari Windows and create wind noise.
The ACS Solution: We use Billet Bases that bolt to the internal roll cage, a Low Profile (2.0") design that respects your Safari Windows, and a fully modular T-track system.
Key Features: ACS ROOF for INEOS
Machined from 6061 T6 aluminum, these bases bolt directly to the INEOS roll cage for ultimate strength, bypassing weak factory rain gutters.
Half Rack: Seamless integration with no interference.
Full Rack: Windows can still open for ventilation (cannot be removed).
Securely mount gear with adjustable load bars that slide into toothed channels. Position your bars exactly where your gear needs them.
Adds only 2.0 inches to the height of your Grenadier Quartermaster, maintaining garage clearance and reducing drag.
Compatible with the GearPOD ROOF. This side-opening storage box features internal locks and pre-marked spots for MAXTRAX and RotopaX.
Works with any Rhino-Rack, Thule, and Yakima accessory that uses standard T-track mounting hardware.
Additional load bars can be added to create a solid platform surface, ideal for photography, observation, or carrying smaller items.
Grade 10.9 black Zi-Ni coated fasteners with Loctite and a dual-stage powder coat finish ensure your rack survives the elements.
Engineered in the USAThe ACS ROOF is built with heavy-duty 1.5mm to 3.0mm multi-wall aluminum. It’s designed to handle the toughest trails without rattling apart, thanks to custom vibration-resistant fasteners.
Available in Two Configurations: Choose the Half Rack (3/4 Platform) for lighter needs or the Full Length Rack for maximum overland utility.
40-70 lbs Rack Weight 750 lbs Max Static (Full) 375 lbs Max On-Road (Full) 2.0" Added Height
"Most racks for the Grenadier just clamp to the gutters, but I didn't trust that for my RTT. The Leitner ACS bolts right into the chassis points. It's incredibly sturdy. I went with the Full Length version, and being able to still pop open my Safari windows for ventilation is a huge plus."
- David S., INEOS Quartermaster Owner Important: Tent Mounting NoticeLow Profile Design: The rack is strong enough for the heaviest tents, but the low-profile design (2.0") makes accessing tent mounting fasteners difficult.
Recommendation: If mounting a tent, we highly recommend our Load Bar Kit, specifically designed for hassle-free tent installation.

Half Rack: No interference; seamless integration.
Full Rack: You can still open the windows for ventilation, but the rack covers them, so the glass panels cannot be completely removed while the rack is installed.
Instead of clamping to the rain gutters (which can be a weak point for heavy dynamic loads), the ACS ROOF bolts directly to the INEOS roll cage using machined 6061 T6 aluminum bases. This provides ultimate strength and stability.
Yes, the rack is rated to support heavy tents (up to 750 lbs static on the Full Rack). However, due to the low-profile design, accessing tent bolts is very difficult. We strongly recommend purchasing our Load Bar Kit for hassle-free tent mounting.
Full Rack: Covers the full roof, weighs 70 lbs, higher capacity (750 lbs static), covers Safari windows.
Half Rack: Covers 3/4 of the roof, weighs 40 lbs, lighter capacity (500 lbs static), zero interference with Safari windows.
No. The ACS ROOF uses a bolt-on assembly that connects to existing points on the INEOS Quartermaster roll cage.

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
