Ultra-Strong 1/4" Aluminum. Zero-Drill Bolt-On. Precision Trail Armor.
Shield the Heart of Your 4WD SystemProtect your Toyota 4Runner’s transfer case with ASFIR’s precision-built aluminum skid plate. As one of the most vulnerable and expensive components of your drivetrain, the transfer case requires armor that can handle direct impacts without adding unnecessary bulk.
Designed exclusively for the 6th Gen gas-powered 4Runner, this plate offers the ultimate balance of strength and weight. ASFIR armor is engineered to survive the world's most demanding terrains while maintaining your vehicle's factory clearance.
The Problem & The Solution:The Pain: The transfer case hangs low and is often protected by thin factory "splash guards" that fold under the weight of a rock strike, leading to catastrophic drivetrain failure.
The ASFIR Solution: We use 1/4" (6mm) laser-cut aluminum reinforced with stiffening ribs to provide rigid, high-clearance protection that slides over obstacles rather than catching on them.
Key Features: ASFIR Transfer Case Protection
Crafted from 6mm laser-cut aluminum for maximum impact resistance with minimal weight gain.
Specifically tailored for the 2025-2026 Gas 4Runner to ensure zero clearance loss and a perfect fit.
Reinforced with strategic ribs in critical stress zones to prevent plate deformation during heavy hits.
Mounted via heavy-duty steel brackets with a zinc coating for superior long-term corrosion resistance.
Engineered with ventilation slots to allow heat to dissipate and prevent drivetrain overheating.
Integrated drain holes allow water, mud, and trail debris to escape easily after your adventure.
At only 18 lbs, this plate provides heavy-duty protection without ruining your fuel economy or handling.
Direct chassis mounting with no drilling, welding, or cutting required. Maintains vehicle resale value.
*Repair costs are estimates. Does not include rental car or lost adventure time.
Engineered for the UnchartedASFIR skid plates aren't just covers; they are structural upgrades. By using 6mm thick aluminum, we provide the rigidity of steel with the weight-saving benefits of modern alloys. This ensures your 4Runner remains nimble on the trails while being fully armored from underneath.

"The transfer case on the new 4Runner is a sitting duck. I swapped out the flimsy factory guard for this ASFIR plate. The fit was perfect, and it’s surprisingly light for how thick it is. I've already slid over a few granite ledges, and it didn't even flinch. If you trail your 4Runner, this is mandatory."

No. This model is engineered specifically for the Gas engine configuration. Hybrid models have different underbody routing that prevents this plate from fitting correctly.
No. This skid plate uses a 100% bolt-on assembly. It utilizes existing factory mounting points on your 4Runner's chassis for a secure and straightforward installation.
Aluminum is roughly 1/3 the weight of steel, which helps maintain your vehicle's center of gravity and suspension performance. Additionally, aluminum naturally resists corrosion, so even if it gets scratched on a rock, it won't rust like steel will.

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

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
