Adding more weight to the lower parts of your crawler greatly enhances its climbing capabilities and improves its stability over challenging terrains, and this can easily be achieved through high quality brass option parts in strategic locations. Following the release of ST Racings C-hubs and lower shock mounts for the Axial SCX10 II, they now offer CNC Brass front Steering Knuckles and Rear Lock-outs as well. The front steering knuckles are machined from high quality brass material with a black finish, then CNC machined again for the bearing holes keeping tight tolerance and precision on the bearing area. When combined with the ST Racing Concepts CNC Brass Rear Lock-out, you add a total of over 100g of weight towards the lower parts of your Axial SCX10 II.
