Engineered for Real Off-Road Protection. 1/4" Aluminum. 100% Bolt-On Performance.
Armor Built for the 6.7L Turbo DieselYour Ford Super Duty is a powerhouse, but its vital organs—the engine oil pan and transmission—are dangerously exposed to trail debris, rocks, and jagged terrain. The ASFIR 4X4 Engine & Transmission Skid Plate is specifically engineered to provide a bulletproof shield for your 2023+ F-250/F-350 without adding the massive weight penalty of traditional steel plates.
Tested in some of the world's harshest environments, this skid plate ensures that a single stray rock won't end your adventure or result in a multi-thousand dollar repair bill.
Why ASFIR Protection:The Pain: Factory plastic guards offer zero protection against impacts, and heavy steel plates can lead to front-end sag and rust.
The ASFIR Solution: We use 1/4" (6mm) High-Grade Aluminum for maximum impact resistance, a No-Drill Installation, and integrated ventilation to keep your 6.7L diesel running cool.
Key Features: ASFIR Underbody Armor
Manufactured from high-quality 6mm aluminum for the ultimate strength-to-weight ratio. Tough enough for rocks, light enough for fuel economy.
No drilling, cutting, or welding required. Uses existing factory mounting points to preserve your truck's structural integrity.
Reinforced with laser-cut ribs to provide superior durability against heavy vertical impacts on the trail.
Supplied with zinc-coated steel brackets to prevent rust, ensuring your armor lasts as long as your Super Duty.
Precision vehicle-specific design ensures an exact fit that hugs the chassis, maintaining your critical ground clearance.
Strategic ventilation slots reduce heat buildup around the engine and transmission while allowing mud and water to drain.
At only 29 lbs, this plate provides heavy-duty protection without causing front-end dive or suspension wear.
Designed with oil drain access holes to make routine maintenance easy without removing the entire plate.
Tested on the Crew Cab 6.7L DieselWe don't believe in "universal" fits. This ASFIR skid plate was specifically CAD-designed and tested on the Ford F-250/F-350 Crew Cab 4WD. It accounts for the unique plumbing and heat shielding of the 6.7L Turbo Diesel engine.

"Living in the Rockies, my F-250 is constantly over rocks. The factory 'guard' is a joke. I installed the ASFIR plate in about 45 minutes in my driveway. It's solid, didn't rattle on the highway, and you can tell the aluminum is high grade. Already took one big hit on a trail and the plate barely had a scratch, while my oil pan stayed perfect."

The ASFIR skid plate is designed with integrated drain holes. In most cases, you can access the oil drain plug without removing the entire plate, though some users prefer removal for a mess-free experience. Removal is quick due to the bolt-on design.
Yes, since this skid plate mounts to the factory frame points, it is compatible with most suspension lift kits that do not modify the main front crossmember or mounting locations.
Aluminum is roughly 1/3 the weight of steel, which prevents your heavy 6.7L front end from sagging further. Additionally, aluminum naturally forms a protective oxide layer, meaning it won't rust when the powder coat is scratched on rocks.
No drilling or permanent modification to your Ford is required. The system is 100% bolt-on using existing factory holes.
This specific part covers the Engine and Transmission. ASFIR offers separate plates for the Transfer Case and Fuel Tank to provide complete front-to-back underbody protection.

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
