This is a set of two optional Axial Beadlock Rock Rings, intended for use with Axial 1.9" Beadlock wheels. These rings will allow you to personalize your rig with a variety of color choices, and also help to protect your wheels while crawling. Most importantly, beadlock rings securely mount your tires to the wheels, eliminating the need to glue your tires which allows you to tune your rig to specific surface conditions by easily mounting different tires or foams to the same set of wheels.
