These brass pivot balls fit in Incision rod ends (IRC00010) and are designed to be the width of Axials pivot balls. This reduces the slop that can be found when using Incision pivot balls on parts designed for Axial rod ends.
We're always amazed at VP's ingenuity and creativity when it comes to RC Crawler parts. These brass balls fit the spot, taking the slop out your build. These are a welcome addition to our hobby shop, Jake's Performance Hobbies.
