King Shocks 18in 4.0 Race Shock 6 Tube Bypass Hose Remote Res 1.25in Shaft Large 1in Bypass Tubes

This is the King Shocks 18-inch 4.0 Race Shock, part number RS4018-BP6H. It's a high-performance shock absorber designed for serious off-road racing and extreme custom builds. The large 4.0-inch diameter body houses a robust 1.25-inch diameter shaft, built to handle the immense forces encountered in demanding terrain. This shock is engineered to provide exceptional damping control and adjustability, allowing you to fine-tune your suspension for specific track conditions or driving styles.

What sets this shock apart is its advanced bypass system. It features six external bypass tubes, each 1-inch in diameter, which allow you to precisely control the damping characteristics throughout the shock's travel. This means you can achieve a softer initial bump response while still maintaining firm control during hard impacts, a critical feature for maintaining traction and stability at high speeds. The remote reservoir further enhances performance by increasing oil capacity and improving heat dissipation, preventing shock fade during prolonged, intense use. The large 4.0-inch body also contributes to this cooling efficiency and provides a solid foundation for the internal valving.

This shock is a substantial piece of equipment, intended for custom suspension setups where maximum performance and adjustability are paramount. It's a popular choice for desert racers, rock crawlers, and anyone building a high-travel off-road vehicle. While installation will require custom fabrication and integration into your vehicle's suspension system, the adjustability and performance gains are notable for those pushing the limits.
