If your Polaris ATV is having starting issues, this replacement starter drive might be exactly what you need to get back on the trails! This is a direct replacement for OEM part numbers 3085394, 3090034, and 3087030, and it fits a huge range of Polaris models from 1995 through 2006. We're talking Magnum 325, 330, 400, and 500 models in 2x4, 4x4, and 6x6 configurations, plus Rangers, Sportsmans, Trail Bosses, and several other Polaris ATV lines. The specs are solid - it features 17 gear teeth with a 39mm outer diameter, counter-clockwise rotation, and measures 91.4mm in overall length. The roller and reduction gear clutch type is built to handle the demands of ATV starting, and the quality matches OEM standards without the dealership price tag. Whether you're dealing with a starter that's grinding, not engaging properly, or just worn out from years of use, this replacement drive can restore that reliable starting performance you expect from your Polaris. Installation is straightforward if you're comfortable with basic mechanical work, though having a service manual handy never hurts. The one-year warranty gives you peace of mind, and the quality construction means this should last through many riding seasons. Before ordering, double-check your specific model year and engine size to ensure compatibility, but if you've got a Polaris ATV from that 1995-2006 era, chances are this starter drive will get you back to conquering mud, trails, and whatever else you like to ride through!
