Description

The PERRIN Lightweight Water Pump Pulley replaces the OEM water pump pulley with a precision-machined, anodized aluminum pulley that reduces rotational mass to free up power and sharpen throttle response.

  • Part number: PSP-ENG-112BK (Black)
  • CNC-machined 6061-T6 billet aluminum with a black anodized finish; laser etched for belt life and a precision fit
  • Weighs only 0.48 lbs — 0.28 lbs lighter than the 0.76 lb OEM pulley
  • Increased horsepower, torque, and throttle response; easy bolt-on installation with basic hand tools (approx. 30 minutes)
  • Compatible with OEM and most aftermarket accessory belts
  • Box contents: (1) PERRIN Water Pump Pulley, warranty & instructions
