Important Vehicle Specific Notes and Recommendations

Toyota 2010 and newer 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 2" 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.

Complete Suspension Upgrade Recommendations

Improving the performance and handling of a 2010 and newer 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: [ $2,425 Delivered ]
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: [ $3,145 - $3,165 Delivered ]
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: [$3,535 - $4,805 Delivered ]
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.

Thank You August 6, 2019
Reviewer: Anonymous Person from Lincoln, NE  
We have to tell you how much we appreciated our King shocks.  We just got back from Silverton, Ouray and Telluride Colorado mountain trails.  Whew! Were they good on the difficult trails.  Can't thank you enough.

Super Happy! August 15, 2018
Reviewer: Adam from Emeryville, CA  
This is a little long, but please read the entire  message. When I saw the YouTube video you did explaining how suspensions work and why you were so enthusiastic about King, it was clear you guys really knew what you were talking about. I looked at hundreds of videos, read hundreds of forum posts and rode in a handful of rigs to try to decide what I wanted suspension wise. And after months of looking, I still couldn't make up my mind, everything seemed like a good choice. In the end, I chose King because it seems to be among if not the best, and the price of other comparable systems I was looking at was within $500-$700 of a full King setup. It's a lot of money, but I just felt if I'm going to spend this much, I might as well get the goods. So I placed the order with you guys and went for broke. Boy am I glad I did.

I could not be happier with the suspension you put together for me. It's unbelievable the difference in ride quality, handling and overall improvement in how the 4runner drives. I laugh at bumps, potholes and speed bumps. I have yet to add the bumpers and winch yet, but fully loaded and with rooftop tent, the truck and it's new suspension are a dream. It's transformed my ride. People stop and stare. Not that I wanted that, but it's amazing to see the look on people's faces when my 10 year old son and I drive by.

Today, we took it out on the trail a bit to Prairie City SVRA in Rancho Cordova, CA. In May, I rode a few trails there and got my ass handed to me, practically ripped off the running board and the rest of the vehicle under carriage barely scraped by unscathed. I've since installed skid plates to avoid that, rock sliders and the King Suspension from Filthy Motorsports. Seriously Ben and Ricardo I couldn't be happier man. Amazing, amazing work. I'm so grateful for your advice, input and knowledge to dial in the right suspension for my application. And also for expectation setting and letting me know it would take 3 months. I'm ok with the wait, I'm so glad I waited and took the time.

Can't thank you guys enough. Seriously. Thanks so much for everything. Super happy.
