This is a brand new voltage regulator (also called a regulator/rectifier) made specifically for Polaris Sportsman ATVs - it fits the 450 HO models from 2014-2018 and the 570 models too. It's from etecgo, comes in original packaging, and has a 90-day warranty. The regulator is a crucial part of your ATV's electrical system - it converts AC power from the stator to DC power for charging the battery and running electronics, while also regulating voltage to prevent overcharging. If your Sportsman is having charging issues, battery problems, or electrical gremlins, a faulty regulator could be the cause. This one is a direct replacement designed to match OEM performance and fit. It comes with a generous 57-inch (145cm) wire harness, which makes installation easier - usually you just disconnect the old one and connect this one, often near the front or side of the engine. The black housing is durable and should handle off-road conditions. Always check your specific model year and engine before ordering to ensure compatibility. A reliable regulator keeps your battery charged properly and protects your ATV's electrical components from voltage spikes. Great for DIY repairs, keeping as a trail spare, or fixing charging problems on your Sportsman. Keep your Polaris running strong with this essential electrical component.
