This pair of aluminium wheel hex adapters is a purpose-built upgrade to widen wheel offset on AXIAL Racing SCX10 II platforms. The components provide a 27mm total width to move wheels outward, improving lateral stability on demanding trail and rock sections.
The design pairs a machined aluminium hex body with a Delrin locating collar. Retention is managed via an O-ring on one side and a spring steel ring plus washers on the opposite side to maintain preload under load. A stainless steel cap head screw secures the assembly to 4mm threaded wheel shafts while the central 4mm bore accepts wheels with a 4mm mounting hole.
Installation follows a clear sequence: mount the adapter to a compatible 4mm threaded shaft, seat the Delrin collar, position the O-ring and spring ring stack as per the part orientation, then torque the stainless screw to secure the wheel. After fitting, verify full suspension travel, steering geometry and wheel/bearing alignment as part of routine setup validation.
