After many requests to offer the stub axles from the Tekno 17mm SCT410 hub adapters separately Tekno has decided to released the stub axles in a package by themselves. These are used when converting your SCT410 to a lightweight 1/8th buggy (EB48SL). They are made from hardened steel and require the other parts in the TKR5570-17 17mm Hub Adapter set for use.
