In response to the poor quality of the OEM hall effect speed sensor we have developed our own unit. We start with a machined aluminum housing, unlike the stock plastic housing which can easily break or crack, even if using the aluminum cap Polaris provided on later models. Our sensor also have larger diameter wires and a thicker housing to prevent wire breakage which is also common with the stock sensor. This hall effect sensor is manufactured right here in the USA with the best electrical components available. Trust this speed sensor to work perfectly and last for years in demanding conditions. Also feature a black anodized finish and waterproof Delphi plug. Installs just like the original, no modifications required. Replaces Polaris part number 4040081 and 4010298. Fits the following Ranger 700 models: 2007-08 Ranger 700 XP 2008-09 Ranger 700 Crew 2007-09 Ranger 700 6x6
