Armor for the 6.7L PowerStroke. No-Drill Installation. 6mm Lightweight Defense.
Maximum Underbody Defense for the Super DutyThe ASFIR 4X4 Engine & Transmission Skid Plate is engineered specifically for the high-torque, heavy-duty environment of the Ford 6.7L Turbo Diesel. While the F-250 and F-350 are built for work, their critical oil pans and transmission housings remain exposed to jagged rocks, stumps, and road debris.
Precision-built (6 mm) laser-cut aluminum plate delivers professional-grade protection without the massive weight penalty of steel. Whether you're running a standard Lariat or a trail-ready Tremor, this skid plate is designed to "Carry Your World" through the toughest terrain.
Why ASFIR Protection:The Pain: Factory "protection" is often just a plastic splash guard that shatters on impact. A cracked transmission case or punctured oil pan on a 6.7L Diesel can easily lead to a $10,000+ repair bill.
The ASFIR Solution: Lightweight, reinforced aluminum armor that absorbs impact energy and protects your drivetrain while maintaining factory ground clearance.
Key Features: Drivetrain Protection
The ASFIR plate uses a 100% bolt-on design, utilizing existing factory mounting points to preserve your truck's frame integrity.
Crafted from high-grade 1/4" aluminum, offering an incredible strength-to-weight ratio that won't rust or sag your suspension.
Specifically tested on Lariat and Tremor packages to ensure zero interference with factory off-road hardware.
Engineered with stiffening and reinforcing ribs to provide even greater structural strength in high-impact zones.
Strategically placed air vents prevent heat build-up, ensuring your Diesel engine and transmission stay within safe temperatures.
Integrated drain holes allow pebbles, dirt, and water to escape, preventing debris buildup between the skid and chassis.
Steel mounting brackets are zinc-coated for maximum corrosion resistance in salt-heavy or wet environments.
Maximum protection with minimal mass. Preserves your front-end alignment and steering sensitivity.
Tested in the World's Harshest TerrainWe don't cut corners. ASFIR armor is tested in the rugged landscapes of the Middle East, ensuring that your Ford Super Duty can handle real-world rock crawling and heavy-duty utility work.

"Living in Texas, I do a lot of driving through ranch land with high-centered trails. The factory plastic 'guard' on my F-250 Tremor was a joke. The ASFIR aluminum plate was a perfect fit. It's solid, didn't require any drilling, and I've already bounced off a few hidden stumps without a scratch on the transmission. Best peace of mind you can buy for a PowerStroke."

No. The ASFIR plate includes specifically engineered ventilation slots that maintain factory-spec airflow around the engine oil pan and transmission housing, even during heavy towing or low-range crawling.
No. This is a 100% bolt-on system. It utilizes existing factory holes in your Ford frame. Installation typically takes 45-60 minutes with standard hand tools.
Yes. This plate was specifically tested on the Ford Tremor package. It replaces the factory-included armor (which is often thinner or less coverage) to provide complete engine and transmission protection.
The plate features drainage openings; however, depending on the exact location of your oil drain plug, some owners prefer to drop the plate for a cleaner oil change. Because it is a simple bolt-on system, removal and re-installation are very straightforward.
No. Aluminum naturally forms a protective oxide layer that prevents deep corrosion. Combined with our zinc-coated steel brackets, this system is built to survive salt, mud, and water indefinitely.

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
