King Shocks 16in 4.0 Race Shock 5 Tube Bypass Piggyback Res 1.25in Shaft Large 1in Bypass Tubes

The 1.25-inch diameter shaft on this King Shocks 4.0 Race Shock is a key indicator of its robust construction, designed to handle the immense forces encountered in demanding off-road racing. This shock absorber features a 5-tube bypass design, allowing for precise tuning of compression and rebound characteristics across different stages of suspension travel. The piggyback reservoir is mounted directly to the shock body, providing a compact solution for increased oil capacity and heat dissipation, which is crucial for maintaining consistent damping performance during extended, high-speed runs.

Built with a focus on durability and adjustability, this shock absorber is intended for vehicles pushed to their limits. The large 1-inch bypass tubes are strategically placed to allow fluid to bypass the main piston at specific points in the stroke, offering a unique damping curve that can be tailored to the terrain and driving style. This level of control helps prevent bottoming out on large impacts while still providing a responsive feel during smaller, faster terrain changes. The overall construction is well-built to withstand the harsh environments of desert racing, rock crawling, and other extreme off-road applications.

When setting up a high-performance off-road suspension, shocks like these are a critical component. The ability to fine-tune the bypass tubes allows racers and serious off-roaders to dial in their suspension for optimal handling and control. While this shock is sold individually, consider how it will integrate with your vehicle's overall suspension geometry and other components to achieve the desired ride and performance characteristics.
