King Shocks 20in 4.0 Race Shock 7 Tube Bypass Hose Remote Res 1.25in Shaft Large 1in Bypass Tubes

This is a King Shocks 20-inch 4.0 Race Shock, part number RS4020-BP7H. It's designed for serious off-road racing and extreme suspension applications where precise damping control is critical. The shock features a large 1.25-inch diameter shaft and 1-inch diameter bypass tubes, all housed within a robust 4.0-inch diameter body. This configuration allows for extensive tuning of suspension characteristics.

The standout feature here is the 7-tube bypass system. Each bypass tube allows oil to flow around the main piston at different points in the shock's travel, giving you independent control over compression damping. This means you can fine-tune how the suspension reacts to bumps and impacts, making it softer in the initial travel for comfort and firmer as it compresses further to prevent bottoming out. The remote reservoir further enhances performance by increasing oil capacity and providing better cooling, which is essential for preventing shock fade during long, demanding runs. The 1.25-inch shaft is strong and built to handle the stresses of racing, while the large 1-inch bypass tubes offer a wide range of adjustment.

This shock is a professional-level component. It's built with the quality and attention to detail that King Shocks is known for, using well-built materials to withstand the rigors of off-road racing. While this shock is sold individually, it's typically part of a carefully engineered suspension system. You'll want to consult with your suspension builder or refer to King Shocks' technical documentation to understand how to best utilize the extensive adjustability of the 7-tube bypass system for your specific vehicle and racing needs.
