The 2660 big bore aluminum shocks in long length are designed as a high-performance upgrade for compatible traxxas rc vehicles. Constructed from durable aluminum, these shocks provide improved strength and heat resistance compared to stock plastic or composite shocks, helping maintain consistent damping under aggressive driving, jumps, and rough terrain. The big bore design allows for increased oil volume, smoother suspension travel, and better handling, while the adjustable shock caps let you fine-tune performance to suit your driving style. These long shocks are compatible with traxxas hoss 4x4 vxl, rustler 4x4 vxl, slash 4x4, and stampede 4x4 models that use the 2660 series big bore shock configuration.
