Important Vehicle Specific Notes and Recommendations
Toyota 2003 to 2009 4Runners are extremely popular platforms for daily drivers, weekend wheelers, expedition use, and desert racing vehicles. Each of these applications require different suspension attributes and Filthy Motorsports works directly with each customer to make sure the spring rates, valving, and overall configuration of the suspension is in line with their needs and expectations. With that in mind, there are a few important things we need to consider when building a well tuned suspension system:

1. The front suspension geometry allows for 9" of wheel travel which is leveraged to just over 5" of movement on the coilover. For the best performance, the coilovers should be set close to mid-shaft or about 1.5" to 2.5" over stock height. For added movement, aftermarket upper control arms (UCAs) can be used to allow for an extra 3/4" of down travel when the coilovers are built with the extended travel option.

2. Do not use coilover preload to lift the vehicle over 2.5" above average stock height. The factory geometry works best at 2" over stock and lifting it beyond 2.5" will cause the CV shafts, steering linkages, tie rod ends, and control arms to run at excessive angles that will reduce ride quality and component life. If you want more than 2.5" of lift and excellent performance, you will need an aftermarket lift kit.

3. The stock length rear shocks are only good for up to 1.5" of rear lift maximum. For rear lift heights over 1.5" and/or the use of 2" bump stop spacers to clear 33" / 285 tires, custom length rear shocks are needed. See the video below for more details.

Complete Suspension Upgrade Recommendations
Improving the performance and handling of a 2003 through 2009 4Runner can be done in many ways on many different budgets, however, it's always best to not spend your hard earned money twice to get your desired results. With that in mind, Filthy Motorsports recommends choosing one of the following options:

1. Performance on a Budget:
If you don't have a lot to spend and your 4Runner will be your daily driver, we recommend these King coilovers up front and King shocks in the rear with factory front upper control arms and factory rear springs.

2. Best Trail Runner Performance:
For those that want the best performance off-road and on the trails and the ability to fit 33" tires, Filthy Motorsports recommends these King OEM coilovers up front built to extended travel and set to 2.5" of lift, and paired with Icon or SPC upper control arms. In the rear we recommend 2" to 3" lift springs paired with 2" bump stop spacers and custom length King rear shocks.

3. Race-Spec Long Travel:
If your driving style or needs require running down logging roads, forest roads or through the desert at speeds over 60mph for extended periods of time, Filthy Motorsports recommends looking into a full race-spec long travel suspension system with coilovers, bypasses and hydraulic bump stops. Contact us directly for details.

King OEM Performance Shock Upgrade Kits are direct bolt-on replacement shocks and/or coilovers for your vehicle and come custom tuned for the ultimate balance of on-road handling and off-road performance. They include all of the necessary hardware you need for a bolt-on installation that can easily be done over the weekend. Custom length shafts and cylinders are available to work with any brand and size lift kit. Additional options include compression adjusting reservoirs, custom colors, internal or external bypass tubes, and race-spec valving.

Servicing, Tuning, and Rebuilding
All OEM upgrade shocks and coilovers are hand-built with the same parts as all of King's other Performance Race Series shocks. They are completely serviceable, tunable, and rebuildable to last a lifetime and it only requires a few simple hand tools, a few hours, and the appropriate King replacement parts from Filthy Motorsports. If you prefer not to do the work yourself, you can always bring (or send) your shocks to us and we will service them for you.
