Description

ASFIR 4X4 Ford Super Duty F-250 Diesel Full Skid Plate Kit (4 Pcs)

6mm High-Grade Aluminum. Diesel-Specific Protection. 100% Bolt-On Armor.

Armor Built for the 6.7L PowerStroke

The 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

Diesel Specific Fit

Custom-contoured to fit around the 6.7L PowerStroke exhaust and DEF tank. No "universal" compromises here.

Ultra-Lightweight

At just 79 lbs for the entire 4-piece kit, it provides maximum protection without sagging your front suspension or killing your payload.

Stiffening Ribs

Integrated reinforcement ribs increase structural rigidity, allowing the 6mm aluminum to withstand massive vertical impacts.

Zinc-Coated Hardware

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 Israel

We 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.

Real Owner Feedback ★★★★★

"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."

- Derek J., F-250 Diesel Owner

Frequently Asked Questions

+ Does this kit fit the Gas engine F-250?

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.

+ Will these plates cause my Diesel engine to run hotter?

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.

+ Can I still change my oil and fuel filters easily?

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.

+ How much ground clearance will I lose?

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.

+ Is the hardware included?

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

California Residents

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
