This starter solenoid relay is a direct OEM replacement tailored for Polaris Sportsman 700 (2002-2004) and Sportsman 600 (2003-2004), compatible with cross OEM numbers 4011251, 3085521 and 4010939.

Custom calibrated coil matches the original electrical load of 600cc and 700cc ATV engines, delivering stable instant current during startup. Reinforced internal copper contacts resist abrasion and high temperature, effectively solving grinding sound, intermittent start and click-only no-start problems.

The fully sealed waterproof housing adapts to muddy, wet and bumpy outdoor riding environments, protecting internal parts from dust and moisture erosion. Same size, bracket position and connector as factory unit, allowing quick bolt-on replacement without any modification.
