This billet 6061 CNC machined spacer will give you 3/8" extra room between the fan blades and the radiator,  perfect for those tight installs into the squarebodies.  It installs between the fan clutch and the fan blades, moving the fan back 3/8 of an inch toward the engine.  It is designed to fit on 94-02 Dodge fan and clutch assemblies, but can also be used on the 89-93 fan and clutch assemblies with some minor modification to the clutch.  With this installed, the entire fan will set behind the clutch, and the fan blades will be 7.25" from the block face,   Made in the USA!
