Griffin Radiators

Griffin Radiators — Custom & Direct-Fit Aluminum Radiators for Performance Builds

Griffin Radiators has been manufacturing high-performance aluminum radiators in Piedmont, South Carolina since 1981, building a reputation on superior cooling capacity, precise fitment, and construction quality that holds up under the demands of built engines, forced induction, and high-output street and race use. Whether you need a direct-fit replacement for a classic muscle car or a custom-built radiator for a one-off chassis, Griffin has the engineering capability and product depth to deliver the right cooling solution for your build.

Direct-Fit Aluminum Radiators

Griffin's direct-fit radiator lineup covers the most popular classic American muscle car and performance vehicle platforms with bolt-in aluminum replacements engineered to the factory mounting dimensions, hose locations, and transmission cooler provisions of each specific application. Two-row and three-row aluminum core configurations provide significantly greater cooling capacity than the original copper/brass radiators, with aluminum's superior heat transfer properties delivering better thermal performance at equivalent or reduced core thickness.

Inlet and outlet diameters, tank configurations, and filler neck locations are matched to OEM specifications on direct-fit applications, ensuring correct hose fitment and a clean, factory-correct appearance in the engine bay. Griffin radiators are TIG-welded with precision-formed aluminum tanks and pressure-tested before shipment for leak-free operation from installation day forward.

Custom Radiators

Griffin's custom radiator program is one of the most comprehensive in the industry, offering made-to-order aluminum radiators built to customer-specified dimensions, inlet/outlet locations, core thickness, and tank configurations. For engine swaps, custom chassis builds, and restomod projects where no direct-fit solution exists, Griffin's custom program delivers a purpose-built radiator that fits the space and cooling demand of the specific application — not a universal unit adapted with brackets and hose reducers.

Custom radiators are built using the same core construction and welding standards as Griffin's production lineup, with lead times and pricing that make custom fabrication a viable option for serious builds rather than a last resort.

Common Applications

Griffin produces direct-fit radiators for Chevrolet Camaro (1967–1969, 1970–1981), Chevrolet Chevelle, El Camino, and Monte Carlo, Pontiac Firebird and Trans Am, Ford Mustang (1964–1973), Ford Torino and Fairlane, Dodge Challenger and Charger, Plymouth Barracuda and Road Runner, and a wide range of GM A-body, F-body, and X-body platforms. Coverage also includes select late-model performance vehicles and truck applications where direct-fit aluminum radiator upgrades are available.

Build Quality & USA Manufacturing

Every Griffin radiator is designed and manufactured in the USA using domestic aluminum and precision CNC-formed components. Core fin density and tube sizing are application-optimized — not adapted from a universal core spec — ensuring the correct balance of airflow resistance and heat transfer surface area for each vehicle's cooling demand. Robotic and hand TIG welding produces consistent, leak-free joints throughout the radiator assembly. Each unit is pressure-tested and visually inspected before shipment.

Installation Notes

Griffin direct-fit radiators are bolt-in replacements on supported applications using factory mounting hardware. Drain the cooling system completely, remove the OEM radiator, and install the Griffin unit using the existing brackets and hardware. Hose connections use OEM hose sizes on most applications. Refill with the correct coolant mixture, bleed the system thoroughly, and verify there are no leaks before returning the vehicle to service. Electric fan upgrades are recommended for builds with significantly increased heat output over stock to maximize the cooling capacity of the new radiator.
