Serpentine Drive SystemSerpentine Drive SystemSerpentine Drive SystemSerpentine Drive System

Serpentine drive systems are now available. The full system runs the water pump, AC, alternator, and (optional) power steering. The simple kit runs just the water pump and alternator. At this time, there is no off-the-shelf system made to run power steering without air conditioning.

Options for the full system include with or without power steering, and finishes in polished billet (standard), chrome, black, or black Onyx (black with machined aluminum highlights). All pulleys, brackets, accessories, AC hose manifold, belt, tensioner tool, water pump, belt, and bolts are included. The power steering setup requires a remote power steering reservoir (not included in all kits). Custom kits are available (choose your upgrades, etc.).
