The basic concept of automotive radiators hasn't changed in more than 100 years! And fans have been hung onto them in a mish-mash of ways for just as long. Since then, aside from materials and design improvements, NOTHING HAS CHANGED...UNTIL NOW!

PROFORM is upending the radiator industry with the introduction of its new Slim-Fit Radiator System! No more cobbling together a core, a fan, possibly a shroud, and gobbling up 8" of valuable front-to-back under-hood space, sometimes leading to clearance problems.


PROFORM has completely rethought how the radiator, fan, thermostat, and shroud can come together seamlessly to create a unified radiator system that is under 4" thick, looks and works great, and is pre-assembled right out-of-the-box, ready for a custom fit into your American V8 muscle car! A hodge-podge of one hundred years of rigged-up cooling paraphernalia has come to an end.


What did we do? With revolutionary engineering we flipped the motor around so instead of hanging on the outside, it's integrated directly into a uniquely designed core made with state-of-the-art brazing technology (with no meaningful cooling compromise). The core itself is a hybrid combination of traditional duel 1" tubes, and full core width extruded tubes. Combine this with a high-performance fan blade inserted into a smooth aluminum shroud, the result is the industry's thinnest, most streamlined look. Every PROFORM Slim-Fit Radiator includes a shroud, electric fan with adjustable thermostat, wiring harness, and radiator cap.
