What is the purpose of the bypass tubes on these shocks?

The bypass tubes allow you to tune the shock's damping characteristics independently of the main piston. By adjusting the flow of oil through these external tubes, you can fine-tune the compression and rebound rates to match your specific driving conditions and vehicle setup.

How does the piggyback reservoir benefit the shock?

The piggyback reservoir increases the shock's overall oil capacity, which helps to dissipate heat more effectively. This improved cooling is essential for maintaining consistent damping performance, especially during prolonged, hard use like off-road racing or aggressive trail riding.

Are these shocks sold as a pair or individually?

These King Shocks are sold individually. You will need to purchase the appropriate number of shocks for your vehicle's suspension setup, typically two or four.

Product Details

With a 1-inch diameter shaft and large 3/4-inch bypass tubes, these King Shocks are built for serious off-road performance. The 3.5-inch diameter main body houses the damping mechanism, while the five external bypass tubes allow for precise tuning of compression and rebound characteristics. This setup is ideal for vehicles that see heavy use in demanding terrain, offering improved control and a more comfortable ride over rough surfaces.

The piggyback reservoir design is a key feature, allowing for increased oil capacity and better heat dissipation. This is crucial for maintaining consistent damping performance during extended runs or when pushing the vehicle hard. The swivel fittings on the reservoir and body make installation easier by allowing you to route lines without kinking, ensuring a clean setup. These shocks are designed to handle the rigors of racing and extreme off-roading, providing a significant upgrade in suspension capability.

These shocks are sold individually. When upgrading your suspension, consider the overall system. Proper installation and setup are essential to get the most out of these high-performance shocks. Refer to the manufacturer's installation guide for specific details on mounting and tuning.
