This well-crafted aftermarket starter solenoid is perfectly compatible with ATV Yamaha Grizzly 400 YFM400 models released from 2007 to 2008. It strictly follows the factory standard OEM number 5TG-81940-00-00.

It acts as a key electrical bridge, transferring 12V power from the battery to the starter motor. This structure ensures smooth engine cranking and reliable ignition during outdoor and off-road rides.

Adopting an integrated fully sealed build, this part adapts easily to muddy, humid and complex field conditions. It can effectively resolve common starting troubles such as delayed cranking, abnormal clicking sounds and engine startup failure.
