Everything You Need In One Kit - Including A/C Compressor, Alternator, Power Steering Pump & Water Pump

This serpentine system has been designed for mounting acessories below the valve covers and in between the width of the heads. Precision CNC-machined from 6061-T6 aluminum for strength and perfect fit. Hardcoated on high wear areas. Clear coated to eliminate polishing in those hard to reach places. This drive kit is designed to fit Ram Jet, Tuned-port, single & multi-carb engines.

The "Ultra" Front Mount Serpentine Kit is available in three different series to suite space and budget requirements.

  • The "Ultra Series" is the top of the line kit with everything offered in the "Ultra" front mount design.
  • The "Deluxe Series" is ideal for cars with minimal engine to radiator clearance.
  • The "Custom Series" is the low cost system that gives up nothing in performance. Uses a non-polished A/C compressor and alternator.
