RE: *** Official Associated SC10B Thread ***
The blue aluminum bodied shocks are shared between the truck and the buggy and the T4.1. The big bores are optional shocks which are a larger diameter, have threaded bodies and Titanium-Nitride coated shock shafts. You can use those too for smoother suspension action. The Proline Powerstroke shocks will fit just the same and have similar features.
