This is the King Shocks 4.5 Race Shock, part number RS4520-BP4P. It's a serious piece of suspension hardware built for demanding off-road racing and extreme custom builds where precise damping control is critical. The large 4.5-inch diameter main body houses a robust 1.25-inch diameter shaft, designed to handle the immense forces encountered in high-speed off-road conditions. This shock is engineered to provide exceptional control and adjustability, allowing you to fine-tune your suspension for a wide variety of terrains and driving styles.

The piggyback reservoir is also adjustable, giving you even more tuning options to manage heat and maintain consistent performance during long, punishing runs. This level of adjustability means you can dial in the ride quality and handling to perfectly match your vehicle's setup and the specific demands of the trail or track. The well-built construction, featuring high-grade materials and King's renowned attention to detail, ensures this shock will perform reliably when you need it most.

When installing shocks like these, it's important to remember that they are a key component in a complex suspension system. Proper setup and tuning are essential to get the most out of their capabilities. Consider consulting with a suspension specialist to ensure these shocks are correctly integrated into your build and tuned for your specific application. This shock is designed for custom applications where maximum performance and adjustability are the primary goals.
