King Shocks 18in 3.5 Race Shock OD Swivel 3 Tube Bypass Piggyback 1in Shaft 3/4 Tube Swivel End Cap

What you get with this King Shocks 3.5-inch bypass shock is a serious piece of suspension hardware built for demanding off-road use. This specific shock features a 3-tube bypass design, a piggyback reservoir for extra fluid capacity and cooling, and a 1-inch diameter shaft for strength. The 3.5-inch outer diameter body houses the main damping components, while the bypass tubes allow you to tune the compression and rebound characteristics independently of the main shock body. This lets you dial in the ride for specific terrain and driving styles, offering a significant improvement over standard shocks.

The bypass design is key here. By routing fluid through the external tubes, you can control how the shock behaves at different points in its stroke. For instance, you can set it up to be soft on small bumps but firm up considerably during large impacts or when bottoming out. This is achieved through the placement and valving of the ports within the bypass tubes. The piggyback reservoir is also crucial; it holds extra shock fluid, which helps keep temperatures down during extended use, preventing shock fade. The 1-inch shaft is a robust component, designed to handle the stresses of off-road racing and hard driving. The swivel end caps make installation easier by allowing you to orient the reservoir and hose without twisting, which is a practical detail when fitting these into tight suspension setups.

This shock is a popular choice for custom off-road builds where precise suspension tuning is essential. While installation requires a good understanding of suspension dynamics and potentially fabrication skills to mount the bypass tubes and reservoir correctly, the adjustability it offers is substantial. It's designed for those who want to fine-tune their vehicle's handling over varied terrain, from desert whoops to rock crawling. Remember to consult the manufacturer's documentation for specific tuning recommendations and installation guidelines to get the most out of this advanced suspension component.
