This matched pair of aluminium wheel hex adapters increases wheel track by 23mm to deliver improved lateral stability on technical crawling lines. Intended for AXIAL Racing SCX10 II platforms, the adapters accept wheels with a 5mm centre hole and secure to 4mm threaded wheel shafts for dependable mounting.
The assembly design combines an O-ring seat on one face with a spring steel retaining ring, compression spring, washers and a stainless screw on the opposite face to clamp the hex firmly. An internal Delrin locating collar provides positive wheel location and prevents independent wheel rotation under torque.
As a practical chassis tune for the SCX10 II, these adapters expand stance without changing axle geometry, providing a robust mechanical means to improve roll resistance and tyre contact during slow, high-traction crawling. by GPM
