Control the airflow through your radiator with DeWitts shroud flaps. They push open at speed when the fan is not in use and allow air to flow out of the shroud freely. When the fan is needed, these flaps suck shut--sealing off the shroud, allowing the fan to pull air through the radiator evenly. They are great additions to any shroud that may have an excess area where air can get trapped, providing a damper to ensure both sides of the radiator are similar. DeWitts flaps are injection-molded from a thermoplastic elastomer which provides a tight seal, aiding the fan for increased airflow across the core. They feature the DeWitts crossed flag logo. Flaps are easily mounted by drilling 1/8 in. holes for the tapered locking pins and square or circle exhaust holes behind the flap. This could be two 1.25 in. holes or a 1.75 in. x 1.25 in. square.

Turn to Allstar Performance high-pressure recovery radiator caps when you turn up the heat. Higher cooling system pressure raises the boiling point of coolant to reduce the risk of overheating—especially in racing applications. Recovery system caps allow coolant to exit the cooling system into an overflow or recovery bottle as the coolant heats and expands. As the system cools, recovery system caps will draw coolant back in to keep the cooling system full. Allstar steel or billet aluminum caps are available in different shapes, styles, and psi limits. Choose the model best suited for your radiator.
