Shock Tuning Options

Tuning Options

Adventure Tune - For smooth on-road and off-road use. NO TOWING/Heavy Loads without adjusters on the shocks. This is our most popular tune for those wanting a smooth ride for mainly street, with some off-road.

Dual Sport Tune - For vehicles with taller lifts or carrying heavy loads without adjusters. Moderate off-road use.

Trail Tune - For vehicles wanting to drive faster off-road or needing better handling. Great for a more dedicated off-road vehicle.

Tuning Options from AccuTune Offroad are based on several factors including the vehicles weight and terrain preference. Tuning stages start at Street Tune and go up to Trail Tune. Each step up in stage will stiffen the valving resulting in better handling, better off-road capability, and better bottoming control at the expense of comfort, especially on the street. Bigger tires and lower air pressures can compensate for the stiffer valving.

Rear Spring Options

Eibach 1” Most popular choice, works great for stock weight or with up to 250 additional pounds of accessories.
Icon 2” Good option for vehicles looking for more height, with at least 250lb of weight in the back.
Icon 3” Overland Ideal for the ultimate overland vehicle with a tremendous amount of weight in back. This includes large tire carrier, bumper, fuel cans, fridge, tent top etc.

For a 2.5" lifted front and level ride:
1" spring with up to 200 lb
2" spring with 400 lb
3" spring with 650 lb

For a 2.5" lifted front slight rear rake:
2" spring with 200 lb
3" spring with 400 lb

**3" spring not recommended with less than 400 lb of constant weight in the back.
**Approximations, every vehicle is different

1 review for 03+ 4Runner and 10+ FJ Cruiser Mid Travel Suspension Kit, Stage 3A – Fox

  1. Laurens

    Installed a variation of this kit onto my 2006 v6 Toyota Prado 120 series. This car is very similar to the 4th gen 4runner. This was the best upgrade I have ever done and has reinvented my car to have the best ride quality I could imagine.

    I shared with Ryan from Accutune the actual weight front and back of my car, the future upgrade plans and intended use. With that, he proposed a set which included the adapted rear FOX2.5 DSC Tundra version made suitable for the Prado. This gives me extra down travel and works great to maintain traction in challenging terrain. He proposed a custom valving. Whilst I am still on a learning curve on offroad upgrades, he gave me the confidence to trust what he was doing. I am living abroad and have many extra options fitted to my car, so getting it right once was key to my upgrade plan. Communication with Accutune to advice what I needed and how to install the whole kit was great. Wouldn’t hesitate to recommend to all with the budget.

    The result of the upgrade is AWESOME! Best ride quality imaginable, particularly offroad at speed. I am driving at high speeds on tough roads with great confidence and high comfort knowing that my suspension can handle all I throw at it and with great comfort. On road ride quality is also very, very good. Much better than imagined. The amount of adjustability of the DSC reservoires is perfect. They are used to change comfort level, driving style (my wife prefers lower settings than I do), driving conditions, or loaded weight. Even one click of difference is noticeable.

    The installation wasn’t without challenges, but all worked well. Had to add extended rear brake lines, and extended rear sway bar end link which I made myself. Wheel spacers where needed to avoid rubbing of my oversized wheels to the remote reservoirs. I had to consult Accutune twice on the installation. Installing the ICON UCA’s and getting the DSC’s in place needed some ‘man handling’. The DSC tube at the front needed some careful bending to improve the clearance on the UCA. Nothing that should deter anybody with access to a good mechanic. Accutune’s aftermarket service is much better than Fox’s so buying this with them is another advantage.

    My car now has the best driving quality off road of any car I know. On road driving quality had improved beyond all expectations as an added bonus. Upgrading my suspension was such a better choice than buying a new car/newer model. My car now puts a huge smile on my face whenever I encounter some challenging terrain.
