What is the purpose of the bypass tubes on this shock?

The bypass tubes allow oil to flow around the main piston, providing adjustable compression and rebound control separate from the primary damping. This lets you fine-tune the suspension's response to different terrain and speeds.

How does the piggyback reservoir benefit the shock?

The piggyback reservoir is mounted externally and helps to increase the shock's oil capacity. This leads to better heat dissipation during prolonged or hard use, maintaining consistent damping performance.

Is this shock sold individually or as a pair?

This King Shocks race shock is sold individually. For balanced suspension performance, it is common to purchase a set for both sides of the vehicle.

Product Details

What you get with this King Shocks RS4016-BP3P is a high-performance 16-inch 4.0 race shock assembly. This unit features a three-tube bypass design and a piggyback reservoir, all built around a robust 1.25-inch diameter shaft. The large 1-inch bypass tubes allow for fine-tuning of suspension damping characteristics, giving you more control over how your vehicle handles rough terrain and high speeds.

This shock absorber is constructed with durability and performance in mind, essential for demanding off-road applications. The piggyback reservoir helps manage heat buildup during extended use, ensuring consistent damping performance when you need it most. The bypass tubes are strategically placed to allow oil to flow around the main piston, providing adjustable compression and rebound control independent of the primary damping circuit. This adjustability lets you dial in the suspension to match specific driving conditions, from crawling over rocks to high-speed desert running. The 1.25-inch shaft is strong and built to withstand the stresses of competitive off-roading.

When installing these shocks, it's important to consult the manufacturer's installation instructions for proper setup and tuning. Proper adjustment of the bypass tubes is key to unlocking the full potential of this advanced suspension component. While this product is sold individually, many builders opt for a complete set to ensure balanced suspension performance on both sides of the vehicle.
