PROFORM: Slim-Fit Radiators

Tight spaces are no longer the enemy. After three years of focused development, PROFORM has unveiled the industry’s first all-in-one integrated radiator system, which boasts a total thickness of only 4”—making it up to 40% thinner than similar aftermarket products.

With an integrated four-corner design, these slim-fit radiators are defined by sleek angles, eye-catching perforations, and an exclusive slant-edge cap, meaning they do not sacrifice under-hood style in the pursuit of cooling performance.

Slim-fit PROFORM radiators are available for direct-fit applications, LS conversion systems, and in universal styles.
