JConcepts is bringing the power to sport-mod monster truck racers with their new Silent Speed 17t brushed motor. Timing is adjustable and the armature is supported by dual ball bearings for smooth operation and efficiency. Rebuilds are simple as replacement brushes and springs are available. Maximum performance is achieved between 115 and 120 degrees Fahrenheit according to JConcepts and motor temperatures should be monitored closely for the longest life and most performance possible. Each motor arrives in a cylindrical tube for a throw back feel and easy transport.
