All PA Performance Starters are 100% New. In many cases we have made improvements to the internal components to increase cranking power or torque and efficiency. The compact design is much smaller than early field-wound applications and the same as current production. On early applications the conversion kit must be used for proper engagement and disengagement when cranking the engine, failure to do so will void the warranty. On current applications where there is already a PMGR starter the OEM wiring must be re-used. The use of "jumper wires" and similar short cuts will void the warranty.
