This is an optional pair of Team Losi Racing 22X-4 X69mm CVA Driveshaft Bones.
These X69mm length CVA bones are the X style driveshaft, which have less lock up in the CV joint and provide more consistent rear grip while accelerating. These are the correct length driveshafts for carpet racing in the #3 and #4 CVA pin location holes for the 22 5.0 when running the 22X-4 rear suspension arms which has become a popular tuning option.
