This product is a rear shock assembly designed as a direct replacement for compatible Losi RC vehicles. It provides consistent damping performance to help maintain rear-end stability, traction, and control during acceleration, cornering, and rough terrain driving. The pre-assembled design allows for fast installation without the need to rebuild individual shock components. Built with durable materials, it is engineered to withstand demanding racing and bashing conditions while delivering reliable suspension response. Ideal for restoring factory handling performance and replacing worn or damaged rear shocks.
