Description

Asfir 4x4 Jeep Wrangler JL Full Skid Plate Kit (5 Pcs) | 4-Door | 3.6L

Complete Underbody Armor for 2018–2025 3.6L Models. 1/4" Aluminum. 100% Bolt-On.

Maximum Protection for the 3.6L Pentastar & eTorque

The Asfir 4x4 5-Piece Skid Plate Kit is the definitive protection solution for 4-door Jeep Wrangler JL owners running the 3.6L engine. Whether you have the traditional gasoline engine or the Mild Hybrid (MHEV) eTorque version, this kit provides end-to-end shielding for your drivetrain and fuel system.

Precision-manufactured using 1/4" (6mm) laser-cut aluminum, this kit is designed for the serious overlander who demands "trail-tough" reliability without the fuel-draining weight of heavy steel plates. At only 72 lbs, it is the lightest way to achieve full underbody security.

The Problem & The Solution:

The Pain: Factory "protection" is often just a thin sheet of metal that bends on the first rock, leaving your oil pan, transfer case, and fuel tank exposed to catastrophic failure.
The Asfir Solution: Our reinforced 1/4" aluminum plates feature structural stiffening ribs and 100% bolt-on mounting to absorb massive impacts and slide over obstacles with ease.

Key Features: The Asfir Difference

Comprehensive 5-Piece Coverage

Shields every vital organ: Engine, Transmission, Transfer Case, Fuel Tank, and both Front and Rear Differentials.

No Drilling Required

Designed as a 100% bolt-on system. Uses existing factory mounting points so you never have to modify your vehicle's frame.

1/4" Marine Grade Alum

High-grade 6mm aluminum provides an incredible strength-to-weight ratio, resisting rust and corrosion indefinitely.

Thermal Efficiency

Built-in ventilation slots ensure your 3.6L engine and transmission stay cool even during low-speed, high-torque rock crawling.

Integrated Drain Holes

Designed with openings for water and mud to escape, preventing the buildup of debris and making cleanup a breeze.

Stiffening Ribs

Each plate is reinforced with structural ribs in high-impact zones to prevent bending under the vehicle's weight.

Zinc-Coated Hardware

All mounting brackets and hardware are zinc-coated for superior corrosion resistance against road salt and moisture.

Manual & Auto Support

Compatible with both Automatic and Manual transmissions (Manual models require factory crossmember).

Engineered Strength, Zero Compromise

Weight is the enemy of off-road performance. By using 1/4" aluminum, Asfir provides the same thickness as premium steel kits but at a fraction of the weight. This 5-piece system protects your entire undercarriage for just 72 lbs, ensuring your Rubicon or Sahara stays nimble on the obstacles.

Jeep Community Feedback ★★★★★

"I've gone through several cheaper sets that rattled and bent. The Asfir kit for my 3.6L JL is on another level. The fitment around the transfer case is tight and professional. I hit a shelf pretty hard last weekend, and the plate didn't even budge—just a small scratch. Highly recommend the aluminum for the weight savings alone."

- Greg M., JL Rubicon Owner

Frequently Asked Questions

+ Will this kit fit the 2-door Jeep Wrangler JL?

No. This specific 5-piece kit is designed for the 4-door LWB (Long Wheel Base) models. The fuel tank skid plate, in particular, has a different length for the 2-door models. Please search for our 2-door specific kits if needed.

+ I have the manual transmission. Do I really need a crossmember?

Yes. Most automatic Wranglers come with the necessary crossmember from the factory, but some manual models do not. The engine/transmission skid plate requires this structural member to bolt onto correctly. Check your underbody against our reference photo above before ordering.

+ How often should I clean under the skid plates?

While we include drain holes, it is good practice to spray out the skids with a high-pressure hose after every mud-heavy off-road trip. This prevents dry mud from trapping heat or causing unwanted vibrations.

+ Is the 1/4" aluminum as strong as steel skid plates?

Aluminum (6mm) is thicker than the standard 3/16" steel used in most kits. While steel is harder, 1/4" aluminum is extremely resilient and absorbs impacts without cracking. The main advantage is that aluminum won't rust if you scratch it on a rock, and it keeps your Jeep's center of gravity lower.

+ Does this kit fit the new 2024 and 2025 models?

Yes. This kit covers the 3.6L Pentastar engine for all 4-door models from 2018 through 2025, including the updated 2024+ refresh models.

Prop 65

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
