This is a optional ST Racing Concepts Aluminum Rear Hex Adapter Set, and
is intended for use with the Team Associated SC10 short course truck.
These CNC Machined aluminum hex adapters allow the Associated SC10 to
use the more standardized 12mm hex type short course wheels. Machined to
be as thin as possible to keep the rear tires of the SC10 under the
body and not to alter the rear width too much, this hex adapter design
provides a much better “grab” on the rims and less likely to round out
the wheel compare to the original SC10 roll-pin design.
