79-93 SBF 5.0 Mustang Polished Serpentine Underdrive Pulley Alternator Kit

  • Sale
  • Regular price $99.95

Kit Includes: Polished aluminum billet 6 groove serpentine alternator, crank and water pump pulleys. Alternator pulley includes a billet nose cone. The Underdrive pulley systems increase engine horsepower by replacing the factory-sized crank and accessory drive pulleys with a smaller diameter pulley so the accessories are slowed, resulting in more horse power transferred to the drive wheels. All pulleys are manufactured from Billet Aluminum, which exceeds factory quality.
