Dual Component Protection. 6mm Aerospace-Grade Aluminum. 100% Bolt-On.
The Ultimate Shield for Your Nissan's DrivetrainYour transmission and transfer case are the heartbeat of your Nissan 4x4—and they sit dangerously exposed to trail hazards. The ASFIR 4X4 Transmission & Transfer Case Skid Plate provides a massive upgrade over flimsy factory covers, offering a heavy-duty 1/4" (6mm) aluminum barrier against rocks, stumps, and debris.
Engineered and trail-tested on rugged terrain, this plate is specifically contoured for the Nissan Frontier, Xterra, and Pathfinder chassis. It delivers maximum coverage for both critical drivetrain components while preserving essential ground clearance for technical crawling.
The Problem & The Solution:The Pain: A cracked transmission housing or a punctured transfer case is a "game-over" mechanical failure that costs thousands in repairs and requires an emergency tow from the trail.
The ASFIR Solution: High-strength, laser-cut aluminum reinforced with structural stiffening ribs and a precision bolt-on design that protects your drivetrain without adding excessive weight.
Key Features: ASFIR Drivetrain Armor
Crafted from high-grade laser-cut aluminum for extreme durability. Provides pro-level protection while weighing only 40 lbs.
Fully bolt-on system. Mounts directly to the chassis using existing factory points—no cutting or welding required.
The plate is reinforced with integrated stiffening ribs to ensure it maintains its shape even after heavy direct impacts.
Precision-cut air vents reduce heat build-up around the transmission, while drain holes allow mud and water to escape easily.
Features zinc-coated steel mounting brackets and marine-grade aluminum that will not rust, even in salty coastal environments.
Tucks tightly to the underbody to maximize breakover angle and keep you from hanging up on obstacles.
Tested for Real-World AbuseWe don't believe in "universal" fitment. This skid plate was specifically tested on V6 4.0L and 3.8L models to ensure that every bolt hole lines up and every sensor is protected. Whether you're navigating the Rubicon or exploring local fire roads, ASFIR gives you the confidence to push further.

"Installed this on my Xterra after seeing how exposed the transfer case was. The fitment was 100% spot on—didn't have to wrestle with it at all. Last weekend I slid off a wet rock and landed right on the plate. It held the weight of the truck and didn't even bend. This is mandatory gear for anyone actually taking their Nissan off-road."

The ASFIR skid plate is engineered to tuck as tight as possible to the chassis. While it adds the thickness of the aluminum (6mm), its low-profile design ensures you retain almost 100% of your factory ground clearance.
Yes. Since this plate mounts to the frame/chassis points, it is compatible with most suspension lifts that do not require major relocation of the transmission crossmember.
No. The ASFIR design includes custom-cut air vents that allow for natural airflow over the transmission pan and transfer case, ensuring temperatures remain within safe operating limits.
Absolutely. This plate is part of a modular underbody protection system. It is designed to integrate seamlessly with ASFIR Engine and Fuel Tank skid plates to create a continuous "belly armor" for your Nissan.
The plate is designed to be easily removed for major servicing. For routine inspections, the drain holes and open architecture allow for visible checks without total removal.
CA Residents: ⚠️ WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
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

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
