This is the Stage 2 piece of Proform's 1-2-3 Series cooling system, a single fan aluminum shroud sized for 23 in. core 1-2-3 Series radiators. It bolts to the four threaded corners of the radiator, so there is no drilling or fabricating, and it comes with pre-threaded holes and hardware for mounting an electric fan. The hole pattern matches Proform's Stage 3 universal electric fans for a clean, matched radiator package.
