JLU T-CASE/FUEL SKID Kit ONLY - 4 door 3.6L, 2.0L, 392 HEMI - ALUMINUM 2018+
This Alpha Series kit (SKU JL4191) armors the fuel tank and transfer case on the 4-door Jeep Wrangler JLU, including the 470-horsepower 392 HEMI. It is the rear-belly module of Artec's modular skid system, giving the JLU a flat, no-overlap protective surface where the factory tins leave gaps. Fits 2018-and-newer 4-door JLU models across the 3.6L, 2.0L, and 6.4L 392 drivetrains.
Key Features
- Covers the fuel tank and transfer case on the 4-door JLU, including 392 HEMI
- 1/4" 6061-T6 heat-treated aluminum skid plates
- 3/16" zinc-plated steel brackets for rust-resistant mounting
- No-overlap layout for a flat belly and improved ground clearance over OEM
- Designed from factory CAD and 3D Creaform laser scans, CNC laser cut and formed
- Artec countersunk custom bolts matched to OEM thread
- Modular: pairs with matching oil, eTorque, and exhaust skids
Fitment & Compatibility
Fits the 4-door Jeep Wrangler JLU (2018-present) with the 3.6L Pentastar, 2.0L turbo, or 6.4L 392 HEMI engine. This is the transfer-case and fuel-tank section; combine it with the matching oil skid, JLU exhaust skid, or full bellypan for complete coverage. For early-production 3.6L trucks, use the pre-2018 fuel-tank version instead.

Frequently Asked Questions
Does this really fit the 392?
Yes. This 2018+ 4-door kit is rated for the 3.6L, 2.0L, and 6.4L 392 HEMI JLU. The rear-belly geometry is shared across those engines.
What about my oil pan?
This module covers the fuel tank and transfer case. Add the matching JLU oil skid (3.6L 2021+ or 3.6L 2018-2020) for the front of the belly.
How do I know if I need pre-2018 or 2018+?
Jeep revised the JLU fuel tank/underbody during early production. This 2018+ kit fits the later configuration; early builds use the pre-2018 version. Match the kit to your truck's fuel-tank layout.
Is welding required?
No. It bolts to factory mounting points with Artec's OEM-thread countersunk hardware.
