ICON V.S. 2.5 Extended Travel Coilover Kit for 07-09 FJ Cruiser / 03-09 4Runner & GX470, 700lb

The ICON Vehicle Dynamics V.S. 2.5 Series Extended Travel Coilover Kit delivers 0–3.5 inches of front lift and vehicle-specific damping tune for the 2007–2009 FJ Cruiser, 2003–2009 4Runner, and 2003–2009 GX470. The kit ships with 700 lb/in upgraded coil springs sized to support added front-end weight from bumpers and winches. Installation requires aftermarket front upper control arms, which are not included.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Vehicle-Specific Valving for Real-World Conditions

ICON configures each V.S. 2.5 Series coilover in both body length and damping tune for the exact application rather than adapting a universal shock. For the FJ Cruiser, 4Runner, and GX470, that means a calibration matched to the factory suspension geometry and the weight distribution of these platforms. The result is controlled body roll on pavement and composed wheel movement on broken terrain, without the compromise of a generic tune.

Extended Travel Requires Aftermarket Upper Control Arms

The extended-travel body length increases front wheel travel beyond what the factory upper control arms can accommodate. Aftermarket front upper control arms must be installed alongside these coilovers. This is a hard fitment requirement, not an optional upgrade. Buyers who have not yet selected control arms should confirm arm compatibility before ordering this kit.

Fully Rebuildable and Revalveable Construction

The 2.5 Series shock body is CAD-plated for corrosion resistance and built around a 7/8-inch shaft with FK rod end bearings for longevity and minimal deflection under load. Every unit is 100% rebuildable and 100% revalveable, so the shocks can be serviced, retuned for a different spring rate, or rebuilt rather than replaced when they reach the end of a service interval.

Features

• 0–3.5 in front lift: adjustable coilover design spans the full lift range
• 700 lb/in coil springs included: higher spring rate supports added front-end weight from bumpers and winches
• Extended travel length: increases front wheel travel; aftermarket upper control arms required
• CAD-plated shock body with 7/8 in shaft: corrosion-resistant finish and FK rod end bearings for extended service life
• 100% rebuildable and revalveable: fully serviceable for an indefinite service life
• Bolt-in design: installs into the OEM front shock location

Specifications

Who This Is For and Isn't

This kit suits 2007–2009 FJ Cruiser, 2003–2009 4Runner, and 2003–2009 GX470 owners who are running or planning to run a front bumper, winch, or other accessories that add meaningful weight to the front end, and who are building a suspension system that includes aftermarket front upper control arms.

The 700 lb/in spring rate is not recommended for stock-weight front ends. Technical notes for this kit limit this spring rate to vehicles with additional weight added to the front. Aftermarket front upper control arms are required and are not included in this kit; the extended-travel coilovers cannot be installed with factory upper control arms. This kit does not fit any model year, make, or model outside the stated fitment.

Common Questions

Do I need new upper control arms to install this kit?

Yes. The ICON V.S. 2.5 Extended Travel Coilover Kit requires aftermarket front upper control arms for installation. The extended-travel shock body length exceeds what factory upper control arms can accommodate, and the coilovers cannot be installed correctly without them. Upper control arms are not included in this kit.

Is the 700 lb/in spring rate right for my build?

The 700 lb/in spring rate in this kit is intended for FJ Cruisers, 4Runners, and GX470s carrying additional weight on the front end, such as an aftermarket front bumper or a winch. For a stock-weight front end, a lower spring rate is more appropriate. Consult the ICON Help Center for spring rate guidance specific to your build.

Will factory wheels and tires still fit after installing this kit?

Factory wheels and tires are compatible with this ICON V.S. 2.5 Extended Travel Coilover Kit. For aftermarket wheels, ICON recommends 17×8.5 with 4.75 in backspace and 0 mm offset, or 18×9 with 5 in backspace and 0 mm offset. The recommended aftermarket tire size is 33×11.50 in; larger tires may fit but could require fender trimming or other modifications.

Can these shocks be rebuilt or retuned later?

The ICON V.S. 2.5 Series shocks are 100% rebuildable and 100% revalveable. The CAD-plated shock body and FK rod end bearings are designed for long service life, and the fully serviceable construction means the shocks can be rebuilt or revalved rather than replaced at the end of a service interval.

Is there a California Proposition 65 warning for this product?

Yes. This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm. This warning applies to California residents under Proposition 65.
