This competition only off-road idler bracket fits 302 and 351 powered Fox bodies in place of the factory emissions pump. It reuses the factory style serpentine belt, shedding weight and simplifying your engine compartment. This rugged cast aluminum part also frees up horsepower as parasitic losses are eliminated. 

Note: Head port plugs and catalytic convertor removal are required with this off-road only modification.

  • Low parasitic drag frees up power
  • Low weight cast aluminum bracket
  • Reduces engine bay clutter
  • 5.0L & 5.8L direct fitment

Super fix
This was far cheaper and much better that a replacement air pump that I didn't need. To maintain proper belt alignment it is essential to keep this pulley in the system, and this is a great way to ensure trouble free operation.
