Radiators for LS Engine Swaps

Flex-a-lite® now has a line of performance aluminum radiators specifically for LS engine swaps in popular cars and Jeeps. The Flex-a-fit® radiators made by Flex-a-lite feature dual-pass design with the inlet and outlet on the passenger side tank. The Inlet is 1.25 inch in diameter, and outlet is 1.50 inch. The passenger sidetank includes a ¼-inch NPT bung for the steam port tube. Side tanks offer Flex-a-lite patented “T” channel design which allows both the radiator and cooling fan to mount without going through the radiator core.

Currently, we offer LS conversion radiators for these applications:
