Product Details

The Proform Parts 66434 is a high-output 100-amp alternator designed for GM applications with simplified 1-wire hookup. Featuring a natural aluminum finish, this alternator eliminates the need for an external voltage regulator and complex wiring, making installation straightforward for both classic muscle cars and street rods.

Key Features:

  • 100-amp output provides reliable power for modern electrical accessories
  • 1-wire design simplifies installation with no external voltage regulator required
  • Natural finish aluminum housing matches stock or custom engine compartments
  • 100% new components ensure maximum longevity and optimal performance
  • Each unit is individually factory tested before shipment
  • Includes quality assurance documentation with specific output performance data
  • Precision-manufactured components assembled by trained technicians using dedicated equipment

This alternator is an excellent choice for hot rods, street machines, and classic GM vehicles where reliable charging performance and clean installation are priorities. The 1-wire configuration self-excites at approximately 1,200 RPM, eliminating the factory charge indicator light circuit while maintaining full charging capability.

Just order the 1108 turn over ball for 2010 Super Duty and received it within (5) days. Just can't wait to put it on and start pulling the trailer with my new diessel.

Quick and Easy

Just recieved my order and the pit jug and spout were perfect. The shipping was very fast and it was by far the best price I could get on these products. Autoplicity is great.

Lowest prices around the web and excellent customer service. The only real issue was the wait between placing the order and when it was shipped. Took 4 days but I chalk that up to the large amount of business they due to their prices being so competitive. For the lowest prices that I've seen I didn't mind waiting a bit longer!

Great online shopping. Easy to navigate and order, telling you just how many product are left so you know if you need to buy now. fast processing and shipping too
