Aluminum T-Case & Fuel Skid Kit for Jeep Wrangler JLU 3.6L/2.0L/392 2018-Up
This Artec Industries Alpha Series kit (JL4191) is the rear-belly foundation for the 4-door Wrangler JLU: flat, no-overlap aluminum armor over the fuel tank and transfer case where the factory tins leave gaps. One kit covers the 3.6L Pentastar, the 2.0L turbo, and the 6.4L 392 Hemi, since all three share the later JLU rear underbody. The plates are 1/4" 6061-T6 heat-treated aluminum on 3/16" zinc-plated steel brackets, modeled from factory CAD files and Creaform 3D scans so they follow the tub instead of hanging below it.
Features
- Fuel tank and transfer case coverage for the 4-door JLU, 392 Hemi included
- 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 clearance over OEM
- Designed from factory CAD and Creaform 3D laser scans, CNC laser cut and formed
- Countersunk bolts matched to OEM threads
- Modular — pairs with the matching oil, eTorque, and exhaust skids
Fits 2018-up 4-door JLUs with the later fuel-tank layout; early-production 3.6L trucks use the pre-2018 tank version, and 2-door Jeeps take the 2-door kit. Add the matching JLU Oil Skid with Oil Door up front, and find the rest of the system in skid plates.
Aluminum T-Case & Fuel Skid Kit for Jeep Wrangler JLU 3.6L/2.0L/392 2018-Up FAQs
Does this really fit the 392?
Yes. The 3.6L, 2.0L, and 6.4L 392 Hemi share the same rear underbody on the 2018-up 4-door JLU, so this one kit covers all three. Engine-specific differences show up at the oil-pan module, not here.
How do I know if my JLU needs this kit or the pre-2018 version?
Jeep revised the JLU fuel tank during early production. This kit fits the later configuration used by the vast majority of trucks; very early 3.6L builds use the pre-2018 tank version. Compare your fuel-tank shape and mounting to the listings if your Jeep is a first-year build.
What about the oil pan?
That is a separate module. Add the matching JLU oil skid with oil door for your engine and year to protect the oil and transmission pans, and the two kits together give you full belly coverage.
