Xtra Speed have introduced new optional parts for the Axial Capra vehicles. First up is a 2-piece front or rear brass axles steering knuckle caps set. The heavy brass parts can be fitted to the front or rear axles and they add weight for improved traction. In addition they improve visual impact with their brake-disc-like appearance. Also new are a steel universal driveshaft set as well as stainless steel centre and front/rear differential skid plates. Available separately the parts help to protect the transmission from rocks and other obstacles on the trail.
