This high-quality aftermarket starter solenoid relay is a direct replacement for the Polaris RZR XP 900 (2011–2013) UTV. It controls 12V power from the battery to the starter motor, ensuring consistent engine cranking。 The heavy-duty sealed housing and pure copper contacts provide excellent resistance to water, corrosion, and vibration, solving common starting issues such as clicking noise, intermittent start, or no-start failure。
