Excellent upgrade

These 6-blade steel fans are manufactured for thermal clutch applications with a universal bolt pattern so they'll fit all years and models of A-Bodies. These top-quality fan blades are a huge improvement over the standard factory 4-blade fan and provide a significant more amount of cooling air moving through the radiator. They're available in 18" diameter to fit most applications.

Notes

  • It is highly recommended that you have 1" of clearance between the fan blade and the fan shroud and that the fan blade sits at least an inch into the shroud for maximum cooling benefits.
  • This item is not eligible for any further discounts or promotional pricing.
  • SHIP NOTE: Item exceeds standard ground freight size/weight, and is not eligible for free ground shipping.
