Precision-crafted from 1/4" (6mm) aluminum, providing heavy-duty armor that is significantly lighter and more corrosion-resistant than steel.
Engineered for a direct, hassle-free installation using factory mounting points—no drilling, cutting, or welding required to protect your Outback.
A comprehensive shield for your engine, CVT transmission, and rear differential, ensuring all vital driveline components are safe from trail impacts.
Integrated ventilation slots maintain optimal airflow for cooling, while dedicated drain holes prevent the buildup of mud, water, and trail debris.
6mm Heavy-Duty Aluminum. Precision Laser-Cut. 100% Bolt-On Armor.
Engineered for Real Off-Road ProtectionThe ASFIR 4X4 Underbody Protection Kit is designed for Subaru Outback owners who refuse to let the pavement limit their adventures. While the Outback is a capable overlander, its vital components—the engine, transmission, and rear differential—remain vulnerable to jagged rocks and trail debris.
Built from precision laser-cut 1/4" (6 mm) high-quality aluminum, this 3-piece kit provides maximum strength with minimal weight. Engineered and tested in harsh desert environments, it ensures your vehicle returns from the trail in one piece.
Why ASFIR ProtectionThe Pain: Factory plastic splash guards offer zero protection against impacts, and one stray rock can lead to a $5,000 transmission failure.
The ASFIR Solution: High-strength aluminum shielding that absorbs impacts, features service-friendly drain holes, and requires zero drilling for installation.
Key Features: Complete Armor System
Uses a 100% bolt-on design into existing factory mounting points. No drilling, cutting, or welding required.
Constructed from 1/4" (6mm) laser-cut aluminum, providing superior impact resistance without the rust of steel.
Built-in air slots prevent transmission and engine overheating while allowing mud and debris to escape.
Includes zinc-coated steel mounting brackets to ensure long-term durability in salted winter road conditions.
At only 39 lbs for the full kit, it protects your Outback without significantly affecting fuel economy or sag.
Internal stiffening ribs are added in critical areas to prevent the plates from bending under high-impact loads.
Includes dedicated access points so you don't have to remove the entire skid plate for routine oil changes.
Vehicle-specific engineering for the 2.5L engine ensures zero rattles and a tight, low-profile fit.
Built to Handle the Harsh OutbackUnlike universal "one-size-fits-most" plates, ASFIR plates are chassis-mounted to handle the weight of the vehicle. Whether you're navigating rocky mountain passes or sandy trails, this kit secures your most expensive mechanical assets.

"Living in Colorado, the underbody of my Outback takes a beating. I installed the ASFIR 3-piece kit in about 45 minutes. Two weeks later, I bottomed out on a hidden rock—instead of a cracked oil pan, I just had a small scratch on the plate. This kit paid for itself in one weekend."

Precision designed for the 5th Generation Subaru Outback. This kit accounts for the specific chassis geometry of the 2.5L powertrain:
2015 - 2018 Subaru Outback Engine: 2.5L Gas Transmission: Automatic CVTOff-Road Ready: This system provides a flat under-surface, allowing you to "slide" over obstacles rather than getting hung up on mechanical components.
No. This specific kit is designed for the 2.5L engine chassis. The exhaust and mounting points differ on the 3.6L model, which requires a different ASFIR part number.
ASFIR has engineered these plates with drain and ventilation holes. In most cases, oil can be drained without removing the front plate. However, for filter access, check your specific 2.5L filter location, as some models may require loosening a few bolts for cleaner access.
Because these are precision laser-cut for the Outback 2.5L, the fit is extremely tight. As long as the hardware is torqued to specification, there is no vibration or "ringing" noise common with universal thin steel plates.
No. The plates feature integrated air slots designed to maintain factory-spec airflow around the engine and transmission. They allow heat to escape while preventing direct rock impact.
No drilling, cutting, or welding is required. The kit includes all necessary brackets to utilize existing holes in your Outback's subframe.

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.

We get it. You've got a lot of choice when it comes to online retailers.
Here's why we think you should shop with us at ExtrailAuto.
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
Great quality purchase. Reasonable price. Fast shipping. Thanks.
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
