Extended WideMaxx^® steel constant velocity shafts offer the ultimate in torque handling and efficient power transfer for high-power brushless applications. On the axle side, bearings secure the drive pins in place to prevent back-out. Large-bore drive pins are press-fit on the differential side and slot into the heavy-duty steel drive cups. The included bearings are rubber-sealed to keep out dirt while a durable black-oxide coating helps prevent rust on the drive gear. Traxxas’ unique, splined telescoping design delivers full-range articulation, so there is never a need to limit suspension travel. Must be used with WideMaxx suspension arms. Steel CV axles must be used with 8654-series 17 mm splined wheel hubs and 7758-series 17 mm wheel nuts.
