    Stay Cool with Champion Core Radiators

    Champion 3-Row Aluminum Radiators utilize brazed-core technology to ensure the highest quality tubing that provides sufficient cooling capacity for approximately 600 to 800-plus horsepower vehicles. Each direct-fit radiator is built with all-welded seams (without epoxy) and comes complete with a standard radiator cap.

    When you’re building a vehicle for high performance, you need to build the entire package, and that includes an upgraded cooling system. A 3 row aluminum radiator is a great upgrade for more efficient and robust cooling capacity, and Champion is the right place to find them.

    Not all radiators are created equal. Champion’s 3 row radiators feature the highest quality tubing and fins and brazed-core technology; they’re designed for a precise drop-in fit and are built without seams or epoxy. With fitments for vehicles from the 70s all the way back to the 30s, Champion radiators are a perfect choice for a restomod project (and if there’s one weak link in vehicles from the 60s and older, it’s their radiators and cooling systems). Cooling systems for select models include all components – the radiator, shroud, dual electric fans, pigtail, controller and all necessary wiring. An electric fan also has the added benefit of reducing parasitic drag on the engine by eliminating a belt-driven fan.

    Champion radiators are also designed with transmission cooler connections, and all are vehicle specific to easily fit with radiator core supports for a true drop-in installation. Champion radiators are designed to deliver cooling capacity for engines up to 600-800 horsepower.
