Smittybilt Aluminum Inner Fender Liners – Armor for Your Engine Bay & Wheel Wells

Keep the dirt, rocks, mud, and trail debris away from your engine bay and undercarriage with elite protection — now available for 2018+ Jeep Wrangler JL / JLU. The Smittybilt front and rear aluminum inner fender liners are built tough to guard your rig from abuse and look sharp doing it.

Whether you’re flexing over rocks, bombing down gravel roads, or forging through mud, these liners provide a durable barrier while enhancing airflow and visibility. With smart venting, optional rock light provisions, and anti‑rattle design, they’re more than just armor — they’re functional upgrades for serious off-road builds.

Choose Your Liner Set

• Smittybilt Front Aluminum Inner Fender Liner Pair — protects the front wheel well and engine bay, adds airflow and visibility to the sides.
• Smittybilt Rear Aluminum Inner Fender Liner Pair — shields the rear wheel wells and underbody from rear-splash, road spray, and trail trash.

You can install one or both sets depending on how much coverage you want — but pairing front + rear gives you full protection.

Key Features & Benefits:

• 🛡️ Rock‑solid Steel/Aluminum Construction – Built from precision aluminum alloy (or steel‑backed mesh), these liners are corrosion-resistant, strong, and made to endure trail strikes.
• 🌬️ Vent & Mesh Panels for Airflow – Hexagonal mesh cutouts provide airflow to help cool brakes and reduce under-hood heat, without letting debris pass through.
• 💡 Rock Light Provisions – Pre-cut ports make it easy to add auxiliary rock / LED lights for better side illumination during night rides or tight trails.
• 🔇 Anti‑Rattle Quiet Design – Engineered with mounting details to reduce vibration and rattling under load—so your ride stays quiet even over rough terrain.
