Increased your electrical demand? Running big fuel and ignition system? Or Perhaps running a fully sick sound system… whichever it is, you will need an alternator upgrade to keep up with your electrical demand.

• Kit comes with a replacement 15% underdriven hard-wearing stainless steel alternator pulley for the perfect belt alignment and to ensure operational reliability at high revs.
• Far surpasses OEM RB alternator current delivery (80A nominal on the stock RB alternator) .
• Bolt-on, simple and no-fuss slick looking CNC Billet aluminium 6061 mounting adapter.
• OEM like belt tensioning mechanism.
• High tensile fasteners.
• Retains OEM alternator wiring harness and connector (R32, M6 ring terminal to be replaced with M8 ring terminal).

As genuine GM LS1 alternators are no longer in production (part number 92513873 and 92058857), we use and recommend the Bosch alternative (part number 1 986 A01 622).

Notes:

• Alternator NOT supplied – Mounting Kit Only.
