This CNC machined 17mm aluminium adapter set is built for TRAXXAS TRX4 Trail Crawler style vehicles to increase track width and stabilise low-speed crawling performance. The adapters include a self-lock concept to help prevent wheel slip when steering over obstacles.
Delivered as a 20pcs kit, these adapters are compatible only with wheels that accept a 17mm hex and will not fit wheels without that interface. The finished surfaces provide a neat aftermarket look and the kit ships with the basic fasteners shown below.
Fit these adapters to widen the wheel track for steadier crawling and better wheel seating; ensure wheel hub compatibility with a 17mm hex before fitting and keep the supplied hardware for correct installation.
