    Direct Fit Aluminum Radiators

  • LSX Swap

    This radiator is a Direct Fit for all 1966-67 Corvettes with manual transmission and LS Motors. Inlet and outlet are on the passenger side. This radiator is designed to fit the original small block core support. This model is oversized compaired to the original, but still fits. It has the pin mounts on the bottom and two small tabs on the front side that eliminates the need for the bracket on the top of the radiator. The stock size radiator fits in the opening of the core support, we designed this radiator so the core of the radiator fills the opening of the core support and the tanks hang off each side. It is almost the same size as the factory BB copper radiator. This radiator features press formed end tanks, dual row core, and serpentine fins. Features Dual 11" Spal fans with 2780 CFM, your best choice for cars with A/C. We put a filler neck on the top of the radiator, passenger side, that eliminates the need for the factory Harrison overflow tank. Radiator comes with 2 rows of 1" tubes, Dual fans, Billet DeWitt's Cap, Temp sensor in the radiator, stem line, Relays, and wiring.

  • DeWitts Chevrolet Corvette Direct Fit Aluminum Radiators are designed to install into the stock mounting and use the factory connections without any modifications or adapters. Many companies offer replacement radiators and most of them require some alterations, even when they claim they fit. Each DeWitts Direct Fit radiator starts with a USA made core that is furnace brazed. These cores feature two rows of cooling tubes, serpentine fin and they are epoxy free. Press formed end tanks are manually tig welded by expert craftsmen, providing the ultimate in strength and appearance. Finding the perfect radiator for your build is simple with optional electric fans and several finish options.

    DeWitts optional "Black Ice" finish is a product specifically designed to adhire to aluminum without any reduction in heat transfer. This is a special two part epoxy paint that is chemically hardened and it shrinks as it cures to a thickness of .001". Every DeWitts aluminum radiator is available with a Black Ice coat as an option.



    • All Aluminum Construction, No Epoxy
    • Simple Installation, No Modifications Needed
    • Two Row Cores
    • 30% More Heat Rejection Than Stock Radiators
