JL/JT Vented Aluminum Inner Fenders - 37" Tire Compatible
JL/JT Vented Aluminum Inner Fenders - 37" Tire Compatible
Keep the trail outside where it belongs. These ARTEC vented aluminum inner fenders for Jeep JL and JT Gladiator models protect your engine bay from the mud, rocks, and debris that come with serious wheeling—while keeping things cool when you're pushing hard on the trail.
Precision-engineered for JL/JT platforms and compatible with up to 37" tires, these laser-cut aluminum fenders deliver OEM+ fitment without the OEM price tag. Made in the USA by Artec Industries and shipped bare aluminum so you can finish them your way.
🔧 What Makes These Inner Fenders Trail-Ready
- Laser-Cut Ventilation: Built-in venting keeps your engine compartment cool without bolting on extra mesh—cleaner look, better airflow
- Stamped Logo Design: Artec's proprietary stamping process adds rigidity and style that sets these apart from flat alternatives
- Up to 37" Tire Clearance: Run bigger rubber with confidence when paired with a proper suspension lift
- Lightweight 1/16" Aluminum: Tough enough to handle trail debris, light enough not to add unnecessary weight
- CNC Precision: Laser-cut and CNC-bent for exact fitment—no grinding, forcing, or "making it work"
- Modification-Friendly: Easily trimmed for coilover or bumpstop clearance without compromising the vented areas
🏔️ Built for Real Off-Road Use
Whether you're rock crawling in Moab, overlanding through the Rubicon, or just hitting your local trails every weekend, these inner fenders keep your engine compartment sealed from the elements that matter while venting the heat that builds up during technical sections.
The extra bottom flange sits directly behind your wheels to prevent mud and grime from sneaking into gaps in your undercarriage—because nothing kills a good trail day like debris in places it shouldn't be. Compatible with trimmed OEM fenders, so they work with your existing setup or your future build plans.
