RADIATOR 1.25in IN/OUT 12.5625IN X 21.5IN DRAG

The AFCO Racing Products RADIATOR 1.25in IN/OUT 12.5625IN X 21.5IN DRAG is purpose-built for high-performance drag racing and extreme motorsport applications where cooling capacity and weight efficiency are non-negotiable. Engineered for vehicles running modified engines, superchargers, or naturally aspirated powerplants at full throttle, this aluminum radiator handles the intense thermal loads generated during quarter-mile sprints and competition driving. Whether you're building a dedicated drag car, street-strip hybrid, or competition vehicle, this radiator delivers the thermal management required to sustain peak engine performance lap after lap.

This drag-spec radiator features 1.25-inch inlet and outlet connections that support high-flow cooling systems with minimal restriction, allowing water pumps to circulate coolant efficiently even at elevated RPM. The compact core dimensions of 12.5625 inches by 21.5 inches maximize cooling surface area while fitting tight engine bays common in purpose-built drag platforms and tube-frame vehicles. AFCO's racing-grade aluminum construction provides superior heat dissipation compared to OEM radiators, critical when ambient air temperatures, engine load, and sustained high-RPM operation combine to create worst-case cooling scenarios during competition.

Drag racers, bracket racers, and serious hot-rodders benefit most from this radiator's lightweight design and optimized core density—every pound counts in a vehicle engineered for acceleration. At 13.35 pounds, it's substantially lighter than cast-iron or heavy-duty truck radiators, reducing unsprung weight and improving weight distribution in competition vehicles. Installation compatibility depends on your vehicle's cooling system configuration, plumbing layout, and tank mounting, so verify that 1.25-inch hose sizing and the 12.5625 x 21.5-inch footprint align with your engine bay constraints before ordering. Pair this with quality coolant, a reliable thermostat rated for high-heat environments, and proper hose routing to maximize cooling efficiency and engine longevity during hard launches and sustained acceleration.
