ICON V.S. 2.5 Series Extended Travel Front Coilover Kit for 2007-2009 FJ Cruiser / 2003-2009 4Runner / 2003-2009 Lexus GX 700lb

The ICON Vehicle Dynamics V.S. 2.5 Series Extended Travel Remote Reservoir Front Coilover Kit fits the 2007–2009 Toyota FJ Cruiser, 2003–2009 Toyota 4Runner, and 2003–2009 Lexus GX, delivering 0–3.5 inches of front lift height adjustability and a 2.5-inch shock body with vehicle-specific valving. The 700 lb/in spring rate is intended for builds carrying added front-end weight such as aftermarket bumpers or winches. Installation requires aftermarket front upper control arms, which are not included.

Larger Body, Better Damping

The 2.5-inch shock body and increased piston area give the coilover more damping range than the stock front shocks on these platforms. That larger swept volume translates to more consistent control across rough terrain, allowing the shock to manage bigger inputs without fading. Vehicle-specific valving keeps the tune balanced for both highway driving and off-road use rather than compromising one for the other.

Remote Reservoirs for Sustained Performance

Remote reservoirs separate additional fluid and gas volume from the main shock body, which reduces heat buildup during extended off-road use. Cooler operating temperatures mean damping stays consistent through long descents, repeated whoops, or back-to-back trail sections where a standard shock would begin to fade. The 7/8-inch shaft with FK Rod End bearings adds structural rigidity and resists deflection under side-load, contributing to longevity in demanding conditions.

Extended Travel Requires Matching Control Arms

The extended-length coilover increases front wheel travel beyond what the OEM upper control arm geometry can accommodate. Aftermarket front upper control arms must be installed alongside this kit: running the extended coilovers without them will bind the suspension and limit the travel gain. The kit is otherwise a bolt-in replacement at the OEM shock location and is compatible with factory wheels and tires. For larger aftermarket tires beyond 33×11.50 inches, fender trimming or modifications may be required.

Features

• Remote reservoir: maintains consistent damping and lower operating temperatures during extended use
• Included coil springs: 700 lb/in rate, engineered for front ends carrying added accessory weight
• 7/8-inch shaft with FK Rod End bearings: corrosion-resistant CAD-plated body, minimal deflection
• Fully serviceable: supports revalves, rebuilds, and CDCV (Compression Damping Control Valve) upgrade

Specifications

Who This Is For and Isn't

This kit suits 2007–2009 Toyota FJ Cruiser, 2003–2009 Toyota 4Runner, and 2003–2009 Lexus GX owners who want extended front wheel travel and 0–3.5 inches of lift, and who are running or planning to run aftermarket front upper control arms and added front-end accessories such as a bumper or winch that justify the 700 lb/in spring rate.

This kit does not fit any vehicle outside the stated 2003–2009 4Runner / 2003–2009 Lexus GX / 2007–2009 FJ Cruiser model years. It does not include upper control arms, which are required for installation. The 700 lb/in spring rate is not recommended for stock or lightly loaded front ends. Tires larger than 33×11.50 inches may require fender trimming or additional modifications.

Common Questions

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

Yes. The ICON Extended Travel front coilover kit requires aftermarket front upper control arms for installation. The extended shock length exceeds the range of the OEM upper control arm geometry, and running the coilovers without compatible aftermarket arms will bind the suspension. Upper control arms are sold separately and are not included in this kit.

Will this kit work with my factory wheels and tires?

Yes. The ICON Extended Travel coilover kit is compatible with factory wheels and tires on the 2007–2009 FJ Cruiser, 2003–2009 4Runner, and 2003–2009 Lexus GX. For aftermarket fitments, ICON recommends 17×8.5 wheels with 4.75-inch backspace / 0 mm offset or 18×9 wheels with 5-inch backspace / 0 mm offset, paired with 33×11.50-inch tires. Larger tires may fit but could require fender trimming.

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

The 700 lb/in spring rate in this coilover kit is recommended specifically for vehicles carrying additional weight at the front end, such as an aftermarket steel bumper or a winch. For stock or lightly loaded front ends, this spring rate may produce a stiffer-than-intended ride. Consult ICON's Help Center guidance on spring rate selection before purchasing if your build does not include significant front-end accessories.

Can these shocks be rebuilt or revalved?

Yes. The ICON V.S. 2.5 Series remote reservoir coilovers are fully serviceable and support revalves and rebuilds. They can also be upgraded to ICON's Compression Damping Control Valve (CDCV) for additional tuning capability. This serviceability means the shocks can be maintained and reconfigured over the life of the vehicle rather than replaced outright.
