Our starter solenoids contain heavy-duty copper contacts that reduce the effect of arcing and extend solenoid life As a global manufacturer of original equipment ignition products, we maintain complete quality control throughout the manufacturing process from componentry to finished product Pure copper battery terminal studs reduce resistance to permit higher current flow, even in the hottest environments, for better performance We understand and expect the demand for quality, our starting and charging system products feature high grade materials for extended service life 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 Our starter solenoids have more pure copper windings than found on most vehicles to create a stronger magnetic fieldPackage Dimensions: 3.031 x 3.031 x 3.625 inches Package Weight: 1.015 lb Package Quantity: 1 UPC: 091769220327 Amperage Rating: 100 A Color/Finish: Silver Connector Gender: Male Connector Quantity: 4 Connector Shape: Round Continuous Duty: Yes Hardware Included: Yes Terminal Gender: Male Terminal Quantity: 5 Terminal Type: Screw Thread Size: 3/8 Voltage: 12 Country of Origin: CN
