Precision laser-cut from premium 1/4-inch aluminum, providing massive underbody strength while being 30% lighter than traditional steel plates.
Specifically engineered for a direct, hassle-free fit using existing factory mounting points—no drilling, cutting, or welding required.
A comprehensive 3-piece system designed to safeguard the most vulnerable underbody components: the engine, CVT transmission, and rear differential.
Features integrated stiffening ribs for maximum impact resistance and precision apertures for heat ventilation and debris drainage.
6mm Heavy-Duty Aluminum. 100% Bolt-On. Complete Driveline Armor.
The Ultimate Shield for Your Subaru AdventureThe ASFIR 4X4 3-Piece Skid Plate Kit is designed for the 2018-2023 Subaru Crosstrek owner who refuses to let a rocky trail stop the journey. While Subaru's Symmetrical AWD is legendary, the factory underbody is largely unprotected, relying on thin plastic splash guards that offer zero resistance to trail impacts.
This kit is precision-built from 1/4" (6 mm) laser-cut aluminum. It delivers high-impact strength to safeguard your engine, transmission, and rear differential without the excessive weight penalty of traditional steel plates.
Why ASFIR Protection:The Pain: The Crosstrek's CVT transmission and oil pan are low-hanging targets. A single rock strike can result in a $5,000+ repair bill and a ruined trip.
The ASFIR Solution: We provide Direct Bolt-On armor that protects all three critical points. Our 6mm aluminum is 30% lighter than steel, ensuring your suspension doesn't sag while keeping your drivetrain bulletproof.
Key Features: ASFIR 3-Piece Armor Kit
Constructed from high-grade laser-cut aluminum, providing the perfect balance of extreme impact resistance and lightweight performance.
Uses a 100% bolt-on assembly. No holes in your chassis means your Subaru maintains its structural integrity and resale value.
Reinforced with structural ribs in high-stress areas to prevent plate deformation during heavy landings on rocks or stumps.
Integrated apertures allow water, mud, and gravel to escape, preventing debris buildup and weight gain on the trail.
Aluminum is naturally corrosion-resistant. Combined with zinc-coated steel brackets, this kit survives salted winter roads effortlessly.
Strategic ventilation slots manage airflow and heat dissipation, keeping your CVT transmission within safe operating temperatures.
Designed with oil drainage ports to allow for routine maintenance without having to remove the entire front plate.
Includes all necessary mounting brackets and fasteners for a complete, professional-grade installation at home.
Engineered for Harsh EnvironmentsWe don't cut corners. ASFIR plates are designed to provide maximum ground clearance by hugging the chassis. The 6mm aluminum thickness ensures that even a direct drop onto a rock "slides" the vehicle forward rather than hooking and stopping you.

"The peace of mind this kit gives me while overlanding is unbeatable. The factory plastic was shredded after my first trip. I installed the ASFIR kit myself in about 2 hours. The plates fit perfectly with zero rattling on the highway, and I've already taken a few hits on the transmission plate that would have surely cracked the case. Best upgrade for a Crosstrek."

Yes. Because the plates mount directly to the chassis factory points, they are compatible with most suspension lifts (like Ironman 4x4 or LP Aventure) that do not relocate the primary subframe mounting points.
The front skid plate features a precision-cut aperture for the oil drain plug. While you can drain the oil with the plate in place, many owners find it cleaner to drop the plate (which only takes 5 minutes) to ensure no oil splashes onto the aluminum surface.
Aluminum (6mm) is the industry standard for overlanding. While steel is technically "harder," aluminum is better at absorbing impact energy and won't rust when scratched. It is more than capable of protecting your Crosstrek from the typical rocky terrain encountered on overlanding trails.
You will lose approximately 1/4 inch (6mm) of ground clearance, which is the thickness of the plate itself. However, because the surface is smooth and flat, you can "slide" over obstacles rather than catching your drivetrain on them, which is a massive net gain for off-roading.
This specific kit is optimized for the Automatic CVT models. While the front and rear diff plates may cross over, the transmission plate is designed specifically for the CVT housing. Please contact us if you have a manual model to confirm compatibility.

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.

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
