Pure copper battery terminal studs reduce resistance to permit higher current flow, even in the hottest environments, for better performance Our starter solenoids contain heavy-duty copper contacts that reduce the effect of arcing and extend solenoid life We understand and expect the demand for quality, our starting and charging system products feature high grade materials for extended service life Our starter solenoids have more pure copper windings than found on most vehicles to create a stronger magnetic field 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 productPackage Dimensions: 3.250 x 3.000 x 5.688 inches Package Weight: 1.53 lb Package Quantity: 1 UPC: 091769026523 Color/Finish: Black, Gold Connector Gender: Female Connector Shape: Round Continuous Duty: No Finish: Dichromate, Plastic Hardware Included: No Terminal Gender: Male Terminal Quantity: 3 Terminal Type: Stud and Blade Voltage: 12 Country of Origin: CN
