Important Vehicle Specific Notes and Recommendations

Toyota 2010 to 2022 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 for a 4Runners:

1. The front suspension geometry allows for about 8" of wheel travel leveraged to about 4" 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, an aftermarket upper control arm (UCA) 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 pre-load to lift the vehicle over 2.5". The factory geometry works best at about 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. 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 2010 to 2022 4Runners 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. Best Performance on a Budget:
If you don't have a lot to spend and your 4Runners 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, Filthy Motorsports recommends these King OEM coilovers up front built with extended travel and paired with SPC Upper Control Arms. In the rear we recommend 1.5" to 2" lift springs paired with these King rear shocks. If you plan to add a significant amount of weight in the form of bumpers, armor, and gear, we'll increase the coilover spring rates as needed.

3. Best Desert Racing Performance on a Budget:
Building a race-race ready desert vehicle can get very expensive very quickly. Luckily, on a relatively affordable budget, the 4Runners can be made to exceed the capabilities of most drivers off-road and in the desert. For moderate to aggressive desert runs and fitting 33" tires, we recommend these King OEM coilovers up front built to extended length and paired with either SPC or Camburg Upper Control Arms. For the rear, we suggest 2-3" lift springs with custom length King OEM rear shocks and 2" bump stop spacers. For extra fine tuning consider adding the compression adjusted and for the most aggressive applications we recommend the rear hydraulic bump stop kit.

4. 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.

Remember, all orders are treated as custom orders and we will review the spring rates, valving, and configuration to make sure they not only fit the vehicle, but also match your expectations and goals.

Free Spring Exchange Program: All King OEM Coilover Kits are covered by the Filthy Motorsports Free Spring Exchange Program. While we always do our best to select the proper spring for your vehicle, if the ones we send you settle the vehicle too high or too low, let us know and we'll swap them out for you.

5 of 5 Customer service and beyond January 7, 2021
Reviewer: Blake from Clovis, CA  
Between Ben’s YouTube videos and my own automotive history, I was sold on the quality/tech/feel of King. The phone call though, that was where I realized I was working with an expert and not a supplier. To be honest, most of the time you hit that order button on with "parts", you kind of say a little prayer to the Internet hoping for freedom from foul disappointment and error. It’s just the way the cookie crumbles. I had a feeling it would be better than that with Filthy Motorsports. When I got off the phone with Ben, I said to myself, "ok, this is that thing I wanted. What I bought was clarity." Without a few key questions from Ben, and some big ah-ha moments in the conversation, I would have been in for some major disappointment when installed what I gambled on as the "correct" recipe of parts. The best part: he says it’s not over after you slap it all on, he wants to make sure the ride is dialed after everything is cycled and settled. Very cool.
