What is a bypass shock and how does it work?

A bypass shock has additional tubes that allow oil to flow around the main piston. This lets you tune the damping force independently for different parts of the suspension stroke, providing a softer ride over small bumps and more control over large impacts.

What does the piggyback reservoir do?

The piggyback reservoir increases the shock's oil capacity and helps with cooling, which is important for preventing fade during hard use. It also houses the adjustable bypass valves, allowing you to fine-tune the damping characteristics.

How do I adjust the bypass valves on this shock?

The bypass valves are typically adjusted using a hex key or a specific tool, turning them to alter the fluid flow path. Refer to the King Shocks installation and tuning guide for specific instructions on adjusting your PR series shock.

Product Details

If you're building a custom off-road rig or upgrading a performance suspension system, you know that controlling wheel travel and damping is critical. This King Shocks 3.0 PR bypass shock is designed to give you that precise control. It features a 12-inch stroke and a 3.0-inch diameter body, which houses the main damping piston and the bypass tubes. The bypass tubes allow you to tune the shock's damping characteristics by controlling fluid flow around the main piston at different points in the suspension cycle. This means you can achieve a softer ride over small bumps while still having ample damping for large impacts.

The piggyback reservoir is a key feature here, offering additional oil capacity and cooling, which is essential for sustained performance during hard off-road use. It also houses the adjustable bypass valves, allowing for on-the-fly tuning of compression and rebound. The 4-tube bypass design offers a wide range of adjustment, letting you fine-tune the ride for various terrains and driving styles. King Shocks are known for their robust construction and the ability to handle demanding conditions, making this a solid choice for serious off-roaders looking to dial in their suspension.

This shock is sold individually. When setting up your suspension, consider how you'll tune the bypass valves to match your vehicle's weight, tire size, and intended use. Proper tuning will make a significant difference in both ride quality and handling performance.
