A subtle but effective upgrade, the Perrin Lightweight Water Pump Pulley helps reduce parasitic drag on your FA engine by trimming unnecessary rotational weight. Precision CNC-machined and finished with Perrin’s signature anodizing for corrosion resistance, this pulley is designed to replace the heavier OEM component with a lighter alternative that contributes to faster revs and improved throttle response.

Shaving weight from rotating engine components — especially those driven by the accessory belt — can have a significant impact on how quickly your engine builds RPM. The Perrin Water Pump Pulley is engineered to maintain factory drive ratios while eliminating rotational mass. This means you don’t compromise cooling performance or belt alignment, and yet you benefit from a sharper driving feel and more efficient engine response.

Ideal when paired with Perrin’s lightweight crank and alternator pulleys, this upgrade is a popular choice among enthusiasts looking to fine-tune their engine’s responsiveness, particularly in naturally aspirated or lightly turbocharged builds.

  • Lightweight CNC-machined design reduces parasitic drag on the engine
  • Maintains OEM drive ratio to avoid over/under-driving the water pump
  • Hard anodized finish for corrosion resistance and long-lasting good looks
  • Compatible with OEM and aftermarket accessory belts
  • Pairs perfectly with Perrin crank and alternator pulleys for a full lightweight setup
