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

This is the King Shocks 20-inch 4.0 Race Shock with a 7-tube bypass and piggyback reservoir. It features a large 1.25-inch diameter shaft and 1-inch bypass tubes, making it a serious piece of equipment for vehicles pushed to their limits off-road. If you're building a custom prerunner, rock crawler, or a high-performance desert race truck, shocks like these are fundamental to controlling wheel travel and maintaining stability at speed over rough terrain.

King Shocks are well-known in the off-road community for their robust construction and tunable performance. This particular shock is designed for applications where extreme damping control is needed. The 4.0-inch diameter main body houses the primary damping circuit, while the 7 bypass tubes allow for a highly adjustable compression and rebound curve. This means you can fine-tune how the suspension reacts to different impacts, from small chop to large G-outs. The piggyback reservoir not only adds oil capacity for better heat dissipation but also houses additional adjustment points, giving you even more control over the shock's behavior. The large 1.25-inch shaft is incredibly strong, resisting bending and flex even under the most demanding conditions. These shocks are built to be rebuilt, allowing you to service and re-valve them for years of hard use.

When installing shocks of this caliber, it's important to ensure your vehicle's suspension geometry and mounting points are designed to handle the travel and forces involved. Proper setup and tuning are key to unlocking the full potential of these race-proven shocks. Consider consulting with a suspension specialist to dial in the settings for your specific vehicle and intended use.
