• Durable construction for repeated load cycles
• Engineered for heavy-duty agricultural electrical systems
• Improves belt stability and reduces wear on rotating components

Installation Tip: Use a proper pulley installation tool to avoid clutch damage, and ensure the pulley seats squarely on the alternator shaft before tightening.
