Designed not only for scale looks with realistic wheels, tires and body, the CR12 is built for performance as well. The steel ladder frame chassis provides the perfect backbone for this rugged rig. The 4-link suspension, threaded shocks, and soft rubber tires give the grip and performance needed to climb over the roughest terrain. Transferring power to the rocks is a compact 3-gear transmission, plastic low-friction slider-type drive shafts, front steel CVA axles, and metal-shield ball bearings.
