Our new carbonfiber beadlock rings have a recessed feature that grips the tire making for more holding power at high speeds!! These are made from 2.5mm thick carbonfiber, making for a rigid, but excetionally light weight option over the stock beadlock rings. They weigh 26g LESS THAN stock rings that come on the Proline Split Six wheels. This makes spinning the tire and wheel combo up easier, freeing up more torque and helps to reduce the ET. Package contains one pair of rings, uses stock supplied hardware that comes with the wheels.
