Flex-A-Lite: Extruded Core Radiator for ’07-’18 Jeep Wrangler JK

Extruded Core Technology from Flex-A-Lite is the future of performance aluminum radiators, replacing multi-core radiators with a new, advanced design. Extruded Core Radiators provide significantly better cooling with a stronger, more durable, and lighter design.

This direct-fit radiator is engineered to bolt into a 2007–2018 Jeep Wrangler JK—no cutting or drilling required. The radiator mounts using the factory location and equipment and includes a 22–24 lb. cap and train petcock.

Features

  • Increased contact area between coolant and aluminum tubes for better heat rejection.
  • Flat surface on which to braze the cooling fins maximizes contact between the tubes and fins for better cooling.
  • Louver patterns in the cooling fins direct airflow for better performance.
  • Wind-tunnel testing has shown significant cooling efficiency over standard tube radiators.
  • Enhanced strength (100 PSI burst rating).
  • Corner subhead reinforces the cooling tube to header connection (an area prone to cracking and leaking in aluminum radiators).
  • Warranty: 2-year transferable.
