This heavy-duty starter solenoid relay is perfectly compatible with Polaris Xpress 300 and Xplorer 400 ATV models of 1996 and 1997, cross-referencing OEM part numbers 3085521, 4010939 and 4011357.

Built with high-quality pure copper winding and thickened conductive contacts, it delivers stable high-current transmission when starting the engine, effectively avoiding poor contact, intermittent startup and solenoid burnout issues. The fully sealed waterproof and dustproof outer shell can resist moisture, mud splash and vibration, suitable for long-term off-road use.

Consistent with original factory size and mounting position, it supports direct bolt-on and plug-and-play installation, no extra wiring or cutting required. It well fixes common starting faults and restores reliable ignition performance for your Polaris ATV.
