Delivers heavy-duty underbody shielding while being 40% lighter than equivalent steel armor systems—ideal for RAM 3500 payload management.
Precision-engineered to bolt directly to factory mounting points for a secure, zero-modification off-road setup that preserves vehicle value.
A comprehensive 5-piece system protecting the intercooler, engine, transmission, transfer case, fuel tank, and DEF system from high impacts.
Marine-grade aluminum and zinc-coated steel brackets ensure your underbody defense stays structural and clean for years.
Complete Underbody Fortress. 6mm Aerospace Aluminum. No-Drill Installation.
The Ultimate 5-Piece Shield for the RAM 3500The 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.
Key Features: The Total Protection System
Utilizes existing factory mounting points on the RAM 3500 frame. No drilling, cutting, or welding is required to secure your armor.
Laser-cut 1/4" aluminum provides superior strength with significantly less weight than steel, preserving your payload and front-end balance.
Comprehensive defense for the Intercooler, Engine/Transmission, Transfer Case, Urea (DEF) Tank, and the 31-Gal Fuel Tank.
Precision-cut ventilation slots ensure consistent airflow to the transmission and radiator, preventing heat soak during heavy towing.
Tested in the World's Harshest TerrainWe 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.
121 lbs Total Kit Weight 6mm Thickness 31 Gal Tank Specific SWB Double Cab Fit
"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."

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.
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.
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.
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.
Yes. Every kit includes zinc-coated steel brackets, high-tensile bolts, and all necessary mounting hardware for a 100% bolt-on installation.

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

I installed this on my M1102A trailer for organizing my camping gear and mounting my RTT and awning. It was a really easy install and was rock solid containing my gear down rugged dirt roads and washes last week. The sliding rear load bar was great for loading the motorcycles.

I’ve had the full-length rack on my Grenadier for about a year, and it has performed flawlessly. Not only is the design simple and aesthetically pleasing, it is highly practical for carrying any load. I consistently have over 400 lbs mounted on my rack at all times, and even through multiple trips through the washboards of Death Valley at 45 mph, the rack has remained steady and strong, with not one fastener coming loose. I’d buy this rack ten times before I’d consider another brand.
Limited space in bed. Now all my gear sits in the rack above. Made all the difference in what I can fit in this truck!!
needed something low profile but strong. This platform hit it out of the park. Put it on my ARE topper and couldn’t be happier! Assembly instructions could be clearer in showing top versus bottom, but got it together easy enough. Need to show the need for squaring up before mounting. Overall break pleased
Fit and finish first class. I made an error on my initial order, reached out to customer service and they had everything squared away with just a couple of emails. Great communication on shipping and shipping progress. Would definitely use these folks again.
I'm happy with my new racks, it's perfect for that I want.
We are very happy the rack fits the painted roof of our ‘25 Bronco Heritage. Leitner right now might be the only company that makes a rack that fits the painted roof. Typical great Leitner attention to detail
