10 Years of Testing. No-Drill Installation. Shark Fin & GearPOD Compatible.
The World's Toughest Platform Rack for the GX550The Leitner Designs ACS ROOF brings 10 years of Active Cargo System engineering and hundreds of thousands of off-road testing miles to the roof of your Lexus GX550. This modular, 3/4 platform rack is engineered to be stronger and lighter than typical systems while maintaining a factory-clean look.
Every ACS ROOF is over-built in Corona, California, designed to "Carry Your World" without failure. It addresses the primary frustrations of luxury SUV owners: permanent modifications, excessive wind noise, and difficult gear access.
Why Leitner ACS ROOF?The Pain: Many racks require drilling into your Lexus's roof, interfere with the shark fin antenna, or make reaching gear a chore.
The ACS Solution: A 100% Bolt-On design that clears the shark fin antenna, features a Wind Noise Reducer, and integrates with the side-opening GearPOD ROOF for effortless access.
Key Features: The GX550 ACS ROOF
The ACS ROOF uses a 100% bolt-on assembly. No permanent modifications to your GX550 roof, preserving your vehicle's resale value.
Fully compatible with the GearPOD ROOF side-opening, water-resistant, locking storage box for instant access to recovery gear.
Load bars slide into toothed channels. Reposition your setup or add bars to create a solid, flat cargo surface as your gear grows.
The rear load bar is specifically designed to clear the Lexus antenna at a low profile, protecting it from impacts on the trail.
Works seamlessly with T-track accessories from Thule, Rhino-Rack, and Yakima, giving you limitless mounting options.
Adding only 4.0 inches to your GX550's height, this rack keeps your center of gravity low and maintains a clean OEM aesthetic.
Removable corner caps make installing auxiliary lighting simple and clean—no drilling or messy zip ties required.
Manufactured with Grade 10.9 black Zi-Ni coated fasteners and a dual-stage powder coat to prevent rust and corrosion.
Over-Engineered PerformanceThe ACS ROOF features heavy-duty aluminum alloy construction with 1.5mm to 3.0mm multi-wall thickness. It is held together by Grade 10.9 fasteners with Loctite to prevent loosening on washboard roads, ensuring it survives the toughest trails.

"The GX550 is a beautiful vehicle, and I couldn't stomach the idea of drilling into the roof. The Leitner ACS Roof bolted right up in less than an hour. The clearance for the shark fin antenna is perfect, and adding the GearPOD was a game changer for keeping my recovery gear accessible and secure. It's incredibly quiet at highway speeds."
- David K., GX550 Owner & Adventurer Important Load Rating NoteCheck Your Manual: While the ACS ROOF is rated for 1,000 lbs static, always follow the Lexus manufacturer's recommended roof weight limits for your specific GX550 trim.

CA Residents: ⚠️ WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
Because the ACS ROOF is a no-drill, bolt-on system that uses factory mounting points, it does not require permanent modifications. This typically makes it much more warranty-friendly than racks that require drilling or structural changes.
No. The rear load bar is specifically engineered with a low-clearance profile to glide over and protect the Lexus shark fin antenna without blocking signal or causing impact damage.
Yes. The system is fully modular. You can add additional load bars to create a solid platform surface for walking, photography, or supporting smaller cargo.
Absolutely. We use Grade 10.9 black Zi-Ni (Zinc-Nickel) coated fasteners. This coating is far superior to standard zinc and is designed to withstand extreme salt and weather environments without rusting.

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
