Overview

Powermaster designed this Chrome 178021-362 GM CS130 Style 105 Amp Alternator to provide maximum power to the 12 Volt charging system on your hot rod, muscle car, truck, audio competition vehicle or sport compact! This highly efficient small case alternator accepts either a 1 wire or 3 wire connection, and features better cooling, with internal and external fans. With 6.61” bolt spacing, this alternator is an excellent replacement for 10/12si units, while the single groove pulley accepts a V Belt.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
