Voltage Regulator – Compatible with Polaris Ranger 800 (2011–2016) – Improved MOSFET Design – Direct Plug-In Replacement – Replaces Part 4012941

Upgrade your charging system with this improved MOSFET voltage regulator/rectifier designed for Polaris Ranger 800 models (2011–2016). The stock regulators on these machines are prone to overheating and early failure, especially when running lights, winches, or other high-draw accessories. This replacement features modern MOSFET technology that runs cooler, regulates voltage more efficiently, and reduces load on the stator. The result is cleaner, more consistent electrical output that helps extend battery life and improve long-term reliability. This is a direct plug-in replacement for the factory unit—no cutting or splicing required. Built with high-temperature components and sealed housing to withstand off-road conditions, it’s a lasting upgrade over the original part. Perfect for owners tired of replacing burnt-out regulators year after year. Replaces OEM Part Number: 4012941 Fitment List 2011–2014 Ranger 800 (Full-Size) 2011–2016 Ranger 800 6x6 2015 Ranger ETX
