Description

ASFIR 4X4 RAM 3500 Full Skid Plate Kit (5 Pcs) | SWB Double Cab

Complete Underbody Fortress. 6mm Aerospace Aluminum. No-Drill Installation.

The Ultimate 5-Piece Shield for the RAM 3500

The ASFIR 4X4 Full Skid Plate Kit is the most comprehensive underbody protection system available for the 2014-2020 RAM 3500 SWB Double Cab. While the 6.7L Cummins Diesel is a powerhouse, its vital components—the engine, transmission, transfer case, fuel tank, and sensitive Urea (DEF) tank—sit dangerously exposed to trail debris and high-centering hazards.

This 5-piece kit is crafted from 1/4" (6 mm) laser-cut aluminum. It provides industrial-strength impact resistance without the massive weight penalty of steel, ensuring your Heavy Duty rig stays agile while protecting thousands of dollars in mechanical hardware.

The Problem & The Solution:

The Pain: The RAM 3500 has a massive wheelbase. High-centering on a rock can easily crack a transmission housing or puncture the plastic DEF tank, triggering "Limp Mode" deep in the backcountry.
The ASFIR Solution: A full-length "belly" shield that allows your truck to slide over obstacles, distributing impact force across the frame with Zero Drilling required.

ASFIR 4X4 RAM 3500 Full Underbody Skid Plate Armor
Key Features: The Total Protection System

100% Bolt-On Install

Utilizes existing factory mounting points on the RAM 3500 frame. No drilling, cutting, or welding is required to secure your armor.

6mm Premium Aluminum

Laser-cut 1/4" aluminum provides superior strength with significantly less weight than steel, preserving your payload and front-end balance.

Five-Point Coverage

Comprehensive defense for the Intercooler, Engine/Transmission, Transfer Case, Urea (DEF) Tank, and the 31-Gal Fuel Tank.

Advanced Cooling

Precision-cut ventilation slots ensure consistent airflow to the transmission and radiator, preventing heat soak during heavy towing.

Tested in the World's Harshest Terrain

We don't cut corners. Every ASFIR plate is reinforced with structural ribs in high-stress zones. By using zinc-coated steel brackets for the main supports, we ensure the hardware remains corrosion-free and the armor stays secure even in high-vibration off-road conditions.

Real Owner Feedback ★★★★★

"Finding a kit that covers everything on the RAM 3500 is rare. The Urea tank protection is a must—I've seen too many people stranded by a cracked DEF tank. This kit fit my SWB Double Cab perfectly. It's rock solid and the aluminum is high-quality, not the soft stuff you find elsewhere. Install was straightforward and non-invasive."

Frequently Asked Questions

+ Will this fit my 2024 model?

This specific full kit is tested for the 2014-2020 chassis. While many components on newer models are similar, we recommend checking individual SKU fitment for the latest 5th gen RAM models.

+ Does this work with rear air suspension?

No. This kit is specifically for models with rear coil springs. Vehicles with factory rear air suspension have different mounting requirements near the fuel and DEF tank area.

+ Do I need to remove the plates for service?

ASFIR designs their plates with drainage and service apertures. Most routine maintenance can be done with the armor in place. However, the bolt-on design allows for quick removal if full access is required.

+ Is aluminum strong enough for a truck this heavy?

Yes. 6mm (1/4") aluminum is the gold standard for high-end off-road armor. It absorbs impact energy better than steel and provides equivalent protection for 99% of off-road scenarios while saving over 100 lbs of weight.

+ Is the hardware included?

Yes. Every 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
