3" Super Flow Air Dam

Fits: 2007–2018 Jeep Wrangler JKU (4-door Unlimited)

The JC Fab Works 3" Super Flow Air Dam is the perfect balance of performance and fitment for builds where space is tight but cooling still matters. Designed to channel high-volume airflow directly to your engine bay, this air dam feeds fresh air to your radiator, transmission cooler, and AC condenser — because on a JKU, all three sit stacked in the airflow path and benefit directly from the increased flow this dam delivers. And as a bonus, it cleans up the look of your front end by concealing that unsightly cross member hanging down beneath the bumper.

Features

• 3" for efficient, targeted airflow to your cooling system
• Cools engine, transmission, and AC condenser — all three sit in the airflow path and benefit directly
• Improved AC performance — the condenser runs cooler, so your AC works more efficiently especially at low speeds and on the trail
• Cooler engine temps reduce thermal stress on engine oil — extending oil life and protecting engine internals longer
• Conceals the exposed cross member for a cleaner, more finished front-end appearance
• Heavy-duty steel construction — ready for the rocks, dirt, and everything in between
• Black powder coat finish
• Bolts directly to factory pre-drilled holes in the frame rail — no drilling required
• Improves engine and transmission cooling efficiency under hard on and off-road use
• Compact profile fits a wide range of off-road builds
• All hardware included

Why You'll Love It

Don't let a tight engine bay hold back your build. The 3" Super Flow Air Dam keeps your engine, transmission, and AC running cool so you can focus on the trail ahead — not your temp gauge or a weak AC on a hot day. Cooler engine temps also mean less heat stress on your oil — so your engine stays protected longer between changes. And it looks good doing it, hiding that exposed cross member for a cleaner front end. Built by JC Fab Works, it's the kind of no-nonsense fabrication that serious day to day drivers and off roaders rely on.

Disclosure: This air dam improves airflow to your cooling system but will not fix underlying overheating conditions such as thermostat issues, radiator leaks, and or other coolant system failures. Cooling performance varies depending on bumper type, winch, grille, or other equipment that may restrict airflow.
