This pair of aluminium wheel hex adapters increases the axle track by 23mm to improve sideways stability when crawling over rocks and uneven terrain. Built for AXIAL Racing SCX10 II platforms, the adapters are compatible with wheels that have a 5mm centre hole and fit 4mm threaded wheel shafts.
One face of each hex uses an O-ring seat to keep the fit tight, while the other side secures with a spring steel retaining ring, a compression spring, washers and a stainless screw. Inside each hex is a Delrin locating collar that prevents independent wheel rotation under load.
When setting up an SCX10 II for slow-speed crawling, these adapters increase stance without altering axle geometry, which helps maintain tyre contact and reduce body roll on technical obstacles.
