KRC Water Pump Pulleys
All KRC pulleys are CNC-machined from 6061 billet aluminum to the highest of tolerances. Serpentine pulleys feature 30% more surface area for the belt to contact than most other manufacturers. Each pulley is machined to SAE specifications then hardcoated to C-70 Rockwell hardness. Each pulley has windows cut to help reduce rotating weight while maintaining the pulley's structural integrity.
