The machining on both the spur gear and the eliminator is impeccable (refer to photos).
Very easy to install. Just pop-off the entire backend of your RC car (for traxxas that's two screws on the top and two screws on the bottom). Once the backend is off, you will be able to remove your clutch assembly by hand (no tools), and just pop the new one in and reinstall the backend same way you took it off). Can be installed in 5 minutes (depending on skill).
