ICON 2003-2009 4Runner / 2007-2009 FJ Cruiser 0-3.5" Lift Stage 7 Suspension System Tubular UCA

The ICON Stage 7 Suspension System delivers 0–3.5 inches of front lift height for 2003–2009 Toyota 4Runner and 2007–2009 FJ Cruiser models, combining 2.5 Series Remote Reservoir front coilovers, 2.5 Aluminum Series Remote Reservoir rear shocks, a tubular Delta Joint upper control arm kit, tubular rear upper and lower trailing arm kit, adjustable rear track bar, and 2-inch rear coil springs into one bolt-on system. Both the front coilovers and rear shocks include ICON's Compression Damping Control Valve, which distinguishes this Stage 7 build from the Stage 6 configuration.

Tunable Compression Damping Front and Rear

The Compression Damping Control Valve (CDCV) fitted to both the front coilovers and rear shocks allows the driver to adjust compression damping without tools. A loaded overlanding rig and an unloaded daily driver can each be dialed to an appropriate ride quality without returning to a shop, a practical advantage for a vehicle that transitions between work, trail, and highway regularly.

Remote Reservoir Cooling and Bump Zone Control

The 2.5 Series Remote Reservoir front coilovers carry additional shock oil volume away from the main body, reducing heat buildup during extended off-road use and limiting the fade that occurs when shock oil overheats. The 2.5 Aluminum Series rear shocks share the remote reservoir design and add ICON's Bump Zone technology, which increases damping force in the final 2 inches of compression travel. The result is a controlled deceleration at the end of the stroke rather than a harsh bottom-out on large hits.

Tubular Steel Links and Delta Joint UCA

The tubular steel rear upper and lower trailing arms replace the OE units with stronger construction, a multi-durometer bushing requiring minimal maintenance, and pinion angle adjustability. The geometry is designed for correct roll steer on and off road. The upper control arms use ICON's patented Delta Joint: a greaseable, zinc-plated, high-angle ball joint that combines the articulation range of a uniball with a sealed housing that resists corrosion and contamination, making it more suitable for daily-driven vehicles than an exposed uniball.

Features

• Bump Zone Technology: heightened damping in the last 2 inches of rear shock compression travel
• Patented Delta Joint UCA: zinc-plated, greaseable, sealed high-angle ball joint upper control arms
• Tubular Rear Links: adjustable upper and lower trailing arms with pinion angle correction and roll steer geometry
• Bolt-On Installation: no cutting or welding required

Specifications

California Proposition 65 Warning: This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm.

Who This Is For and Isn't

The Stage 7 system suits 2003–2009 Toyota 4Runner and 2007–2009 FJ Cruiser owners who want the full Stage 6 component set plus front and rear CDCV adjustability, particularly those who vary between loaded overlanding use and unloaded daily driving and want to tune compression damping for each without tools.

This system does not fit any 4Runner generation outside 2003–2009 or any FJ Cruiser outside 2007–2009. Coilover height settings are calibrated for a stock-equipped vehicle; heavily accessorized builds may require the optional 700 lb/in expedition spring (sold separately). Remote reservoir brackets may conflict with certain aftermarket bumper mounts and windshield washer bottle locations.

Common Questions

What is the difference between the Stage 7 and Stage 6 systems for the 4Runner and FJ Cruiser?

The Stage 7 system includes every component in the Stage 6 configuration (tubular Delta Joint upper control arm kit, 2.5 Series Remote Reservoir front coilovers, 2.5 Aluminum Series rear shocks, 2-inch rear coil springs, adjustable rear track bar, and tubular rear upper and lower trailing arm kit) and adds ICON's Compression Damping Control Valve to both the front coilovers and rear shocks for tool-free, on-the-fly damping adjustment.

Can compression damping be adjusted without removing the shocks?

Yes. The Compression Damping Control Valve on both the front coilovers and rear shocks in this Stage 7 system is designed for end-user adjustment without tools, allowing compression changes to suit different terrain conditions or cargo loads without disassembly.

Does this system work with OEM wheels and tires?

The Stage 7 system is confirmed compatible with OEM wheels and tires on the 2003–2009 4Runner and 2007–2009 FJ Cruiser. Tires up to 33x11.50 inches are noted as a recommended aftermarket size; larger tires may fit but could require fender trimming or other modifications.

Are the shocks and coilovers serviceable after installation?

The shocks and coilovers in this Stage 7 system are fully serviceable per Application Note #55. The Delta Joint upper control arms use a greaseable design intended to extend service life, and the rear shocks use one-piece impact-extruded aluminum cylinders for corrosion resistance over time.

Will the remote reservoir brackets interfere with other modifications?

Per Application Note #35, the remote reservoir mounting brackets in this Stage 7 system may interfere with certain aftermarket bumper mounts and windshield washer bottle locations. Buyers planning to run an aftermarket front bumper should confirm clearance before purchasing.
