March Performance Chrysler V-Belt Pulley Kits

March Performance Chrysler 383-440 V-belt pulley kits are precision CNC-machined to run perfectly true. The 3-piece kits are machined from 6061 T-6 aluminum for extra strength and long wear, and covered with a "no polishing" clear powdercoated finish. The pulleys are available in Performance Series or a high water flow ratio. Performance Series pulleys typically create up to 12 hp at the rear wheels by reducing accessory drag. They also eliminate belt throwing and are designed for normal street driving. High water flow ratio pulleys increase cooling by increasing water flow and fan speed. This helps at critical low-speed driving, where most overheating occurs.
