Artec Industries JL4161 Full Bellypan w/Oil Door for 2018-2020 Jeep JLU 3.6L 4WD

Vehicle Fitment

• 2018-2020 Jeep Wrangler JLU Sport (4-Door Unlimited, 3.6L Pentastar V6, 4WD)
• 2018-2020 Jeep Wrangler JLU Sport S (4-Door Unlimited, 3.6L Pentastar V6, 4WD)
• 2018-2020 Jeep Wrangler JLU Sahara (4-Door Unlimited, 3.6L Pentastar V6, 4WD)
• 2018-2020 Jeep Wrangler JLU Rubicon (4-Door Unlimited, 3.6L Pentastar V6, 4WD)

Fitment Notes

• Designed for the mid-production 2018-2020 JLU 3.6L motor mount configuration - does NOT fit early-production 2018 JLU units built before Jeep's mid-year motor mount change (those require JL4125)
• Does NOT fit 2021 or newer JLU 3.6L models - Jeep revised the motor mount configuration again for 2021, requiring a separate Artec SKU for that year range
• 4-Door Unlimited (JLU) body style only - does NOT fit the 2-Door JL Wrangler
• 3.6L Pentastar V6 only - does NOT fit 2.0L Turbocharged I4, 3.0L EcoDiesel, 6.4L HEMI V8 392, or 4XE PHEV variants
• eTorque Skid (for 48V eTorque battery) and Exhaust Skid add-on modules are available separately for the 4-Door JLU 3.6L and 2.0L - they are NOT included with this full bellypan purchase
• OEM gas tank skid removal required during installation; for easiest removal, perform install with fuel tank near empty
• 1.5" or greater lift is recommended for optimal ground clearance when running this bellypan system
• Requires general mechanical skill; installation recommended for those comfortable with basic hand tools

Features

• Complete Alpha Series full bellypan system covering all four primary underbody zones - engine oil pan, transmission pan, fuel tank, and transfer case - in a single purchase
• Designed from factory OEM CAD files and 3D Creaform laser scan data for precise fitment to the 2018-2020 JLU 3.6L underbody layout and motor mount geometry
• CNC laser cut and CNC formed using custom-rolled dies for high-strength panel geometry and perfect contour fitment to OEM components
• Non-overlapping skid plate panel design maximizes structural rigidity while keeping overall system weight near OEM levels
• Integrated oil door on the engine oil pan section allows oil changes without removing the full skid system
• All fasteners beneath the skid plates are countersunk for a completely smooth, snag-free underbody surface - minimizes rock catch points on the trail
• Pressed-in nuts on steel mounting brackets enable single-tool removal of any individual section for quick field servicing
• Fuel tank drop is eliminated via an integrated additional strap and new crossmember - no need to fully drop the tank for removal or servicing
• Bolts directly to OEM transfer case crossmember and frame using heavy-duty flat-head bolts that match OEM thread - no aftermarket crossmember required
• Modular design allows any individual section to be removed independently without disturbing the rest of the installed system
• Provides 3/4" of ground clearance improvement over OEM factory skid plate assembly
• No-rust construction - bare aluminum skid panels and zinc-plated steel mounting brackets resist corrosion in all off-road environments
• American-made product manufactured by Artec Industries in North Salt Lake, UT

Product Description

The Artec Industries JL4161 is the Alpha Series Full Bellypan System engineered specifically for 2018-2020 Jeep Wrangler JLU 4-Door 3.6L Pentastar V6 models running the mid-production motor mount configuration. Artec divides the 3.6L JLU bellypan lineup into three distinct year ranges - early-production 2018 (JL4125), 2018-2020 (JL4161), and 2021+ - because Jeep made motor mount changes at both the mid-2018 production point and again for the 2021 model year. The JL4161 is calibrated to the underbody geometry of 2018-2020 JLU units built after that initial motor mount revision; using the wrong year variant will result in misalignment with OEM mounting hardware. Every panel was developed from factory OEM CAD files and 3D Creaform laser scan data, ensuring precise, factory-matching contour fitment across all four coverage zones.

Built from 1/4" thick 6061 T6 heat-treated bare aluminum skid panels with 3/16" zinc-plated steel mounting brackets, the JL4161 weighs approximately 86 lbs total - adding roughly 10 lbs over the factory skid assembly while delivering substantially greater coverage and impact resistance. The system yields a 3/4" ground clearance improvement over the OEM setup, and Artec recommends pairing it with a 1.5" or greater lift for optimal clearance during trail use. The non-overlapping panel design and CNC formed construction ensure maximum panel stiffness throughout. All fasteners are countersunk for a completely flat underbelly, and the integrated oil door on the forward section allows oil changes without removing the skid - a significant maintenance convenience for regular trail drivers.

The JL4161 covers all four primary underbody protection zones in a single purchase: engine oil pan, transmission pan, fuel tank, and transfer case. The fuel tank drop is eliminated by an included additional strap and new crossmember, and the entire system mounts directly to OEM hardware without requiring an aftermarket transfer case crossmember. Each panel section can be removed independently for zone-specific servicing without disturbing the rest of the installation. Owners who want additional coverage for the 48V eTorque battery or the exhaust system can add those dedicated Artec modules separately - they are not included in this kit. The JL4161 is the correct selection for 2018-2020 JLU 3.6L owners who want complete, factory-engineered underbody protection in one comprehensive aluminum package.
