Check mounting, wiring and pulley fitment

Match the exact alternator to your engine and accessory drive. Check mounting points, case clearance, pulley type and alignment, belt configuration, electrical connector and regulator requirements. A vehicle name alone does not confirm compatibility across every model or engine combination.

The one-wire designation applies to the listed V-belt models; do not assume the Commodore LS units use the same wiring arrangement. Check the individual product and installation instructions for connection details.

Choose output to suit your electrical load and confirm the charging cable, connections and protection meet the installation requirements. A listed amperage alone does not establish charging output at idle.
