6.8mm thick. These hub hexes (with faux disc) are 6.8mm wide/thick which is stock for the 4tec. If you want to space your wheels out by 1.2mm more per side get traxxas part tra3654 which are 8mm thick/wide. Just a tech note if you’re trying to run 1/10 touring car wheels/slicks or protoform Vta wheels you may need to space your wheels out to reach 190mm wide track width. This review is not about the durability of the plastic.
Great replacement parts for the 4tec, haven't worn out any of them yet and they make a great, inexpensive scale aspect for any 12mm hex replacement. The only thing that would make them better is if they were metal, can't beat them for the price though. Have used on scx10 projects.
