Collection: Alternators & Accessories - Brackets, Pulleys & Belts

Browse alternators and charging-system drive components, including mounting brackets, alternator pulleys and replacement belts. Choose by the exact vehicle or engine application, electrical connections and installed accessory-drive arrangement.

Alternators and electrical compatibility

The range includes Proflow PowerSpark 100- and 140-amp listings, with selected one-wire V-belt units and Holden Commodore LS serpentine-pulley applications. Check each part number for its case style, regulator, pulley, connector and specified fitment.

Do not assume every internally regulated alternator uses a one-wire connection. Compare the listed wiring arrangement with your vehicle's charging system and follow the manufacturer's installation instructions. Have an auto electrician confirm cable sizing, circuit protection, earthing and any changes required for the selected alternator.

Choose output to suit the vehicle's electrical load and check the manufacturer's output information at relevant operating speeds. A headline amperage rating alone does not establish charging capacity at idle or compatibility with the existing wiring.

Mounting brackets

Bracket listings cover selected small-block Chev, Ford Windsor 351W, Holden V8 and Commodore LS configurations. Match the specified mounting side and position, water pump style, engine mounting points and alternator dimensions. For LS applications, check the relevant VT–VZ or VE–VF bracket arrangement rather than assuming all LS accessory layouts are the same.

Confirm belt alignment and clearance to the chassis, steering, hoses and other accessories, especially with low-mount brackets or engine conversions. Refer to the individual listing for kit contents and any additional hardware required.

Pulleys and replacement belts

Match V-belt, serpentine and Gilmer components to the installed drive system. Check pulley bore, offset, diameter and belt profile; a matching shaft bore alone does not establish compatibility. For Gilmer replacements, confirm tooth profile and pitch, belt width and length against the drive kit specifications.
