This MOSFET voltage regulator is designed as a direct replacement for factory regulators used on select Polaris RZR models that are prone to overheating and inconsistent charging performance, particularly when running higher electrical loads. The MOSFET-based circuitry regulates voltage more efficiently than conventional shunt-style designs, allowing the unit to operate at lower temperatures while providing cleaner, more stable electrical output. By reducing excess stator load, it helps support proper battery charging and overall electrical system reliability. The regulator installs using the factory-style connector with no wiring modifications required, making it suitable for routine replacement or electrical system repairs. Covered by a 90-day limited warranty and a two-year manufacturer warranty. Compatible with Polaris RZR 570, 900, 1000, RS1, Turbo, and Pro XP models listed below.
