KRC Denso & Delco Alternator 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.

KRC's alternator pulleys are furnished with two spacer adapters, enabling it to fit either a .670" shaft Delco or a .590" shaft Denso alternator.
