Direct replacement for 6 rib GM alternator pulleys
Stainless Steel M4 bolts
Designed for 17MM / .669 size shaft alternators
This is a direct replacement 6061 Billet 6-Rib Alternator Pulley for most all GM style alternators using a 17MM / .669 size shaft. This pulley is universally compatible with almost all aftermarket and factory accessory drive systems.
These pulleys are offered in this size to accommodate custom installations, and it is up to the installer to verify proper fitment prior to ordering and may require a longer or shorter belt in some applications where the replaced pulley is different in diameter.
