Now you can get the same fan that the Professional Teams use in World of Outlaws Dirt Late Models! This fan is a replacement for the old 19" Steel 4 blade fans. Competition tested and used by the best, this composite 3 Blade, 17" diameter fan has a 5/8" diameter center bore, standard bolt pattern.
Features and benefits:
Ultra light weight
Stiff - holds shape and moves air at speed
Smaller diameter - better fit with radiator and eliminates fan hitting power steering lines
Uses the least HP out of all 3 blade fans tested!
From the fan center mounting flange, the fan blades extend back towards the engine 1.5". From the same mounting flange, the fan blades extend forward towards the radiator 1.25".
Highly recommended to use a fan shroud for maximum airflow and rock protection. Cross member shields should also be used to keep car from dragging track and scooping mud up into steering rack / fan area to ensure maximum life of components. This will eliminate torn steering rack boots, broken crank triggers and a damaged fan.
