751104 Works on 2012 2017 Dyna and V Rod Front and Rear Pipe and 20

These USA-made Jims O2 sensor wrenches are specifically designed to handle M14, 4-wire heated oxygen sensors. The real beauty of these tools is that they allow you to remove or install the sensors without having to pull the entire exhaust system off the bike. This is a huge advantage when you are diagnosing EFI issues or performing routine maintenance on Dyna, Softail, and V-Rod models. They provide the necessary clearance and leverage to get into tight spots where a standard wrench just won't fit. Built with the durability you expect from Jims, these wrenches are a practical addition to any Harley mechanic's diagnostic toolkit.
