This 12V starter solenoid relay is precision built for Polaris Sportsman 500 (2006–2010) and 800 (2007–2012) ATV models. It replaces OEM part 4012001 with identical mounting holes, terminal layout and electrical rating, allowing quick and easy installation without modification.

Featuring a heavy‑duty coil and high‑current internal contacts, it delivers reliable power transfer to the starter motor while resisting overheating and wear. The sealed protective housing improves durability against water, dust and off‑road vibration.

This solenoid solves common starting failures including slow cranking, constant clicking, no electrical response and intermittent start failures. It restores full starting function and is a cost‑effective, durable repair part for your ATV.
