Yeah Racing have introduced the new double joint driveshafts for the XRAY T4 and T3. The shafts are made from premium spring steel and come hard-coated for improved wear characteristics. They improve precision, and steering efficiency at high steering angles and reduce the wheel chatter compared to standard drive driveshafts. The double joint driveshafts come with two 5x10x3mm high-grade ball bearings.
