Replace your electric EZ-Start system with the recoil pull starter for racing applications where weight savings are critical. It includes a heavy-duty spring and cord for long-lasting trouble-free operation. Installation requires the starter backplate (#5274) and starter shaft (#5277) (EZ-Start equipped motors already have these parts installed). If the engine was not originally equipped with a starter, a different crankshaft is also required. Use Traxxas part 5219 (IPS) or 5221 (multi-shaft) crankshaft.
