All Hybrid Racing radiators feature dual-core, all-aluminum construction with high-precision TIG welds. This radiator integrates the necessary ports for the Coolant Temperature Sending Unit and the Fan Switch, eliminating the need for special adapters and inserts.

Each K-Series swap radiator was carefully designed by Hybrid Racing to take into account both the chassis' dimensions and mounting points, as well as the K-Series' motor's coolant inlet and outlet. These radiators simplify the K-Series engine swap by eliminating the need for custom mounting brackets and by providing a guaranteed fit for your specific swap.
