This is an optional ST Racing Concepts CNC Machined Aluminum Front Shock Body Set, and is intended for use with the Team Associated SC10 4x4. These CNC Machined aluminum shock bodies are threaded, allowing for very precise ride height/spring pre-load adjustments just like the stock shocks, but are available in Gun Metal, Red and Silver that which when matched with other STRC option parts can give your truck a whole new look.
