Description

ASFIR 4X4 Chevrolet Silverado 1500 / GMC Sierra 1500 Full Skid Plate Kit (5 Pcs)

Full Underbody Armor. 1/4" Aluminum Construction. 100% Bolt-On Fit.

The Ultimate Shield for Your Half-Ton Rig

The ASFIR 4X4 Full Skid Plate Kit is the definitive protection solution for the 2018+ Chevrolet Silverado 1500 and GMC Sierra 1500. Designed for those who take their trucks beyond the pavement, this 5-piece kit creates a fortress beneath your chassis, shielding every critical component from the radiator to the fuel tank.

These ASFIR plates are trail-tested in some of the most unforgiving terrain on the planet. Built from high-quality 1/4" (6 mm) aluminum, this kit offers the brute strength of steel without the heavy weight penalty, ensuring your 5.3L rig stays agile and efficient.

Why ASFIR Protection:

The Pain: Modern half-ton trucks come with massive, exposed fuel tanks and fragile transmission pans. A single "bad line" on a trail can lead to a $5,000 repair bill or a stranded vehicle.
The ASFIR Solution: Our 5-piece system provides a continuous "sliding surface." It features reinforced ribs for impact resistance and a 100% Bolt-On design that requires zero modifications to your frame.

Key Features: Total Underbody Armor

No Drilling Required

Uses factory mounting points for a true 100% bolt-on installation. Maintain your vehicle's structural integrity and resale value.

Full 5-Piece Coverage

Shields the Front, Engine, Transmission, Transfer Case, and Fuel Tank. No component is left exposed to the trail.

Precision 6mm Aluminum

Constructed from marine-grade 1/4" aluminum. Offers high impact resistance while being significantly lighter than steel alternatives.

Ground Clearance Focused

The low-profile design is vehicle-specific, hugging the chassis to maximize ground clearance for rock crawling and deep ruts.

Smart Ventilation

Strategically placed airflow slots ensure your transmission and engine stay cool, while drain holes let mud and water escape.

Reinforced Rigidity

Features internal stiffening ribs to provide additional structural strength in high-impact zones like the differential and fuel tank.

Rust-Proof Protection

Natural aluminum resistance to corrosion means these plates won't rust out even after heavy use in snowy or salty environments.

All Hardware Included

Comes with high-tensile fasteners and zinc-coated steel brackets for a secure, long-lasting installation.

Tested in Unforgiving Environments

ASFIR 4X4 has spent decades refining underbody protection for off-road expeditions. This 5-piece system is designed to act as a singular shield, allowing your Silverado or Sierra to slide over obstacles that would otherwise snag on exposed factory parts. At 85.1 lbs, this entire kit is lighter than just two comparable steel plates.

Real Owner Feedback ★★★★★

"The peace of mind this kit gives is incredible. I took my AT4 through some rocky trails in Moab, and these plates saved my transmission and gas tank multiple times. The install was exactly as advertised—bolt-on with no drilling. It's the best insurance policy you can buy for your truck."

- Marcus T., Sierra 1500 Owner

Frequently Asked Questions

+ Will I need to remove these plates for an oil change?

ASFIR designs their plates with serviceability in mind. The engine skid plate typically includes an access port for the oil drain plug. For full filter changes, the bolt-on design allows for the quick removal of individual plates in under 10 minutes.

+ Does the kit fit trucks with a suspension lift?

These skid plates are designed to mount to factory chassis points. They fit perfectly with most standard leveling kits and mid-travel suspension systems. If your lift kit uses a massive drop-bracket for the front crossmember, minor modifications may be required.

+ Why aluminum over steel?

Weight and corrosion. Aluminum is roughly 1/3 the weight of steel, which helps maintain your truck's payload and suspension performance. Additionally, aluminum will not rust once the finish is scratched, making it ideal for snowy or salty road conditions.

+ Is the installation really 100% no-drill?

Yes. ASFIR engineers their kits to utilize original factory threaded holes or existing chassis slots. No drilling into your frame is required, which keeps your manufacturer warranty intact.

+ How much ground clearance will I lose?

Minimal. ASFIR designs their plates to hug the chassis as tight as possible. In most areas, you will lose less than 1/4 inch of clearance, while gaining the ability to slide over obstacles that would otherwise snag on exposed factory components.

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
