The SS-580 and Standard Ignition Starter Solenoid is the perfect choice for those looking for a reliable, durable and powerful solution to their starting and charging system needs. This solenoid features heavy-duty copper contacts that reduce the effect of arcing and extend the solenoid life. It also contains more pure copper windings than found on most vehicles to create a stronger magnetic field and pure copper battery terminal studs to reduce resistance and permit higher current flow. Additionally, our polyester-insulated magnet wire, cadmium-plated copper discs and solid contact bolts reduce voltage drop and deliver full battery power to the starter while providing greater protection against electrical overload. As a global manufacturer of original equipment ignition products, we maintain complete quality control throughout the manufacturing process from componentry to finished product, ensuring our customers get the highest quality products on the market. SS-580 and Standard Ignition Starter Solenoid is the perfect choice for those looking for the best in performance, durability, and reliability.
