Description

ASFIR 4X4 Subaru XV Crosstrek Underbody Protection Kit (3 Pcs) - 2018-2023

6mm Heavy-Duty Aluminum. 100% Bolt-On. Complete Driveline Armor.

The Ultimate Shield for Your Subaru Adventure

The 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

1/4" (6mm) Aluminum

Constructed from high-grade laser-cut aluminum, providing the perfect balance of extreme impact resistance and lightweight performance.

No Drilling Required

Uses a 100% bolt-on assembly. No holes in your chassis means your Subaru maintains its structural integrity and resale value.

Stiffening Ribs

Reinforced with structural ribs in high-stress areas to prevent plate deformation during heavy landings on rocks or stumps.

Smart Drainage

Integrated apertures allow water, mud, and gravel to escape, preventing debris buildup and weight gain on the trail.

Rust-Free Protection

Aluminum is naturally corrosion-resistant. Combined with zinc-coated steel brackets, this kit survives salted winter roads effortlessly.

CVT Cooling

Strategic ventilation slots manage airflow and heat dissipation, keeping your CVT transmission within safe operating temperatures.

Service-Friendly

Designed with oil drainage ports to allow for routine maintenance without having to remove the entire front plate.

Full Hardware Kit

Includes all necessary mounting brackets and fasteners for a complete, professional-grade installation at home.

Engineered for Harsh Environments

We 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.

Real Owner Feedback ★★★★★

"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."

- Mike J., Subaru Crosstrek Owner

Frequently Asked Questions

+ Will this kit fit if my Crosstrek is lifted?

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.

+ Do I need to remove the plates for oil changes?

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.

+ Is the 6mm aluminum strong enough for rock crawling?

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.

+ How much ground clearance will I lose?

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.

+ Does this kit fit the manual transmission model?

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.

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
