Premium 1/4" aluminum construction delivers heavy-duty underbody protection at only 79 lbs, preserving your truck's payload.
Precision engineered to bolt directly to the Ford F-250 chassis using factory mounting points—no cutting or welding required.
Includes specialized plates for the DEF tank and fuel filtration system, safeguarding the most vulnerable Diesel-specific parts.
Marine-grade aluminum and zinc-coated brackets ensure your armor won't rust, even in salt-heavy or extreme off-road environments.
6mm High-Grade Aluminum. Diesel-Specific Protection. 100% Bolt-On Armor.
Armor Built for the 6.7L PowerStrokeThe ASFIR 4X4 Full Diesel Skid Plate Kit is specifically engineered to shield the unique vulnerabilities of the Ford Super Duty F-250 Diesel. Unlike gas models, your Diesel truck carries a sensitive DEF tank and complex fuel filtration systems that sit dangerously low to the ground.
Manufactured and trail-tested in extreme conditions, this 4-piece kit is crafted from 1/4" (6 mm) laser-cut aluminum. It provides heavy-duty impact resistance without the massive weight penalty or rust issues associated with traditional steel plates.
Why ASFIR Protection:The Pain: A single rock strike to your DEF tank or fuel filter can trigger a "Limp Mode" error, leading to thousands in repairs and a ruined expedition.
The ASFIR Solution: Lightweight, marine-grade aluminum armor that covers every critical component from the steering rod to the DEF tank, installed with zero drilling.
Key Features: ASFIR Diesel Armor
Custom-contoured to fit around the 6.7L PowerStroke exhaust and DEF tank. No "universal" compromises here.
At just 79 lbs for the entire 4-piece kit, it provides maximum protection without sagging your front suspension or killing your payload.
Integrated reinforcement ribs increase structural rigidity, allowing the 6mm aluminum to withstand massive vertical impacts.
Supported by corrosion-resistant steel brackets and high-grade hardware to ensure the plates stay put for the life of the truck.
Precision Engineering from IsraelWe don't believe in generic fitments. The ASFIR Diesel kit uses laser-cut technology to ensure every drainage hole and ventilation slot aligns perfectly with your F-250's service points and airflow needs.

"The DEF tank on the 6.7L PowerStroke is basically a target for rocks. I installed the ASFIR kit because I didn't want to be stranded by a sensor error 50 miles from the nearest road. The fit is incredibly tight to the body—I actually gained a tiny bit of perceived clearance compared to the bulky factory plastic."

No. This kit includes components specifically for the Diesel fuel filter and DEF tank. Gas engine models use a different configuration. Please see our Gas-specific F-250 skid plate kit for the proper fitment.
ASFIR engineers these plates with integrated ventilation slots to maintain factory-spec airflow. Aluminum also dissipates heat better than steel, ensuring your 6.7L engine and transmission remain within safe operating temperatures.
Yes. The plates are designed with access apertures for routine maintenance. While dropping the plates provides maximum room, basic filter changes and oil drainage can be performed through the provided openings.
Loss of clearance is minimal, typically less than 0.25 inches. Because the plates provide a smooth, flat surface, they actually help the truck "slide" over obstacles rather than getting hung up on exposed components like the DEF tank.
Yes, every ASFIR kit includes zinc-coated steel brackets, high-tensile bolts, and all necessary mounting hardware for a 100% bolt-on installation.

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

Fit and finish first class. I made an error on my initial order, reached out to customer service and they had everything squared away with just a couple of emails. Great communication on shipping and shipping progress. Would definitely use these folks again.
I'm happy with my new racks, it's perfect for that I want.
We are very happy the rack fits the painted roof of our ‘25 Bronco Heritage. Leitner right now might be the only company that makes a rack that fits the painted roof. Typical great Leitner attention to detail

I installed this on my M1102A trailer for organizing my camping gear and mounting my RTT and awning. It was a really easy install and was rock solid containing my gear down rugged dirt roads and washes last week. The sliding rear load bar was great for loading the motorcycles.

I’ve had the full-length rack on my Grenadier for about a year, and it has performed flawlessly. Not only is the design simple and aesthetically pleasing, it is highly practical for carrying any load. I consistently have over 400 lbs mounted on my rack at all times, and even through multiple trips through the washboards of Death Valley at 45 mph, the rack has remained steady and strong, with not one fastener coming loose. I’d buy this rack ten times before I’d consider another brand.
Limited space in bed. Now all my gear sits in the rack above. Made all the difference in what I can fit in this truck!!
needed something low profile but strong. This platform hit it out of the park. Put it on my ARE topper and couldn’t be happier! Assembly instructions could be clearer in showing top versus bottom, but got it together easy enough. Need to show the need for squaring up before mounting. Overall break pleased
