What is KDSS and does this shock work with it?

KDSS stands for Kinetic Dynamic Suspension System, a feature on some Toyota 4Runners and FJ Cruisers that helps improve on-road handling while allowing for more wheel travel off-road. These King Shocks are designed to fit both vehicles equipped with KDSS and those without it.

How do I adjust the compression on these shocks?

The shocks feature an external knob that allows you to adjust the compression damping. Turning the knob changes the resistance the shock provides when the suspension compresses, letting you tune the ride for different conditions.

What is the purpose of the shaft guard?

The shaft guard is a protective sleeve that fits over the shock absorber's shaft. Its main purpose is to shield the shaft and its seals from impacts by rocks, mud, and other debris encountered during off-road driving, helping to prevent damage and premature wear.

Product Details

The 2.5-inch diameter piston within these King Shocks coilovers is a key design choice, allowing for a larger volume of oil to manage heat during aggressive driving. These are built for 2003 and newer Toyota FJ Cruisers and 4Runners, whether they came equipped with KDSS (Kinetic Dynamic Suspension System) or not. The adjustable compression knob lets you fine-tune the damping characteristics, giving you more control over how the suspension reacts to bumps and terrain. This is especially useful when you're loading up your vehicle for a trip or changing driving conditions.

Constructed with a heavy-duty 2.5-inch diameter cylinder and a 7/8-inch hard chrome plated shaft, these shocks are built to withstand the rigors of off-road use. The included shaft guard helps protect the shock shaft from impacts with rocks, debris, or other trail hazards, extending the life of the seal and the shock itself. The coilover design means the spring and shock are integrated into one unit, simplifying installation compared to separate spring and shock setups. You'll find the adjustability allows you to dial in a ride that’s comfortable for daily driving but capable when you leave the pavement behind.

When installing these coilovers, you'll want to ensure you have the necessary tools for spring compression and adjustment. It's always a good idea to consult the manufacturer's installation guide for specific torque values and procedures to ensure proper setup. These shocks are designed to work with your vehicle's existing suspension mounting points, making them a direct replacement for the factory units.
