Upgraded MOSFET Voltage Regulator – Fits Polaris Sportsman 450 570 850 1000 and Scrambler XP 1000 (2010–2019) – Plug-and-Play Replacement – Replaces 4015231 4014543 4015230

Upgrade your Polaris charging system with this Quad Logic Upgraded MOSFET Voltage Regulator, engineered for Sportsman 450, 570, 850, 1000, and Scrambler XP 1000 models (2010–2019). Unlike traditional regulators that overheat and overload the stator, this advanced MOSFET design runs cooler, provides cleaner voltage output, and reduces electrical strain for improved reliability. The result is longer battery life and stable performance for machines equipped with high-demand accessories such as winches, lights, or heaters. This regulator is a direct plug-and-play replacement that installs in minutes using factory connectors—no cutting or modification required. Built with upgraded internal circuitry, heavy-duty heat sinks, and reinforced wiring terminals, it ensures consistent charging even under extended load conditions. Perfect for riders who want to eliminate common charging issues and extend electrical system life.
