TVR Ball-X Revo & Maxx truck axles

TVR introduce their Ball-X driveshafts for the Traxxas Revo and Maxx line of monster trucks. The special design of the driveshaft and wheel axle coupler using balls over conventional pins makes for a three times larger contact area to distribute torque loads more efficiently, more reliable and without any binding. The construction also allows for angles up to 50 degree for smaller turning circles for more low-speed agility. The driveshafts comes as pairs with suitable differential outdrives.
