Team Associated RC10B6.3 Factory Team Carbon Fiber HT +1 Steering Block Arms. These HT (High Traction) steering block arms offer a +1 geometry change. This change will lead to less aggressive steering off center while providing a smoother turn-in feeling and improved drivability in high traction conditions. Package includes one optional pair of steering block arms intended for the RC10B6.3, however, they will work for other Team Associated models as well.
