ICON V.S. 2.5 Series Front Coilover Kit with Remote Reservoir and CDCV for 1996-2002 Toyota 4Runner

The ICON Vehicle Dynamics V.S. 2.5 Series Front Coilover Kit with Remote Reservoir and CDCV is a bolt-on front suspension upgrade for 1996–2002 Toyota 4Runner, providing 0–3 inches of lift height adjustability and extended wheel travel through a 2.5-inch shock body with vehicle-specific valving. Aftermarket upper control arms are required for installation (Application Note #18).

More Travel, Better Damping

The 2.5-inch shock body delivers increased piston area compared to stock components, which translates directly to stronger damping force across a wider range of terrain and speeds. Extended travel means the front suspension can absorb larger obstacles without bottoming out, keeping the tires in contact with the ground and the steering predictable. Vehicle-specific valving is tuned for the 4Runner's weight and geometry, so the damping curve is calibrated for this application rather than adapted from a generic platform.

Remote Reservoir for Sustained Performance

The external remote reservoir increases total fluid volume, which delays heat buildup during sustained off-road use. Cooler fluid maintains consistent damping characteristics on long runs where a standard shock would begin to fade. The reservoir also separates gas and fluid more effectively, reducing aeration and keeping damping response predictable lap after lap or trail after trail.

External Tunability with CDCV

The included CDC Valve provides 10 external adjustment positions from soft to firm without removing the shock. Drivers can dial in a comfort-oriented setting for highway miles, then firm up for technical terrain or loaded touring, with no tools required beyond the adjuster itself. This tunability is built into the kit; no separate CDCV purchase is required.

Features

• 0–3 inch lift adjustability: coilover height set via threaded body; heights referenced to a stock-equipped vehicle
• 2.5-inch shock body: larger piston area than stock for improved damping capacity
• 10-position CDCV: external compression damping adjustment from soft to hard, included in kit
• Remote reservoir: extends consistent damping duration and reduces operating temperature during heavy use
• 6061 aircraft-grade aluminum CNC components: CAD-plated shock body; 7/8-inch induction-hardened, chrome-plated shaft
• FK rod end bearings: extended longevity and minimal deflection at the mounting points

Who This Is For and Isn't

This coilover kit suits 1996–2002 Toyota 4Runner owners who want 0–3 inches of front lift with extended travel, external damping adjustability, and sustained off-road performance from a remote reservoir system. It works with OEM wheel and tire sizes and with the recommended ICON Alloys fitments listed above.

This kit requires aftermarket upper control arms and is not compatible with stock upper control arms (Application Note #18). Remote reservoir mounting brackets may interfere with aftermarket bumper mounts and windshield washer bottles (Application Note #35). Lift heights stated are for a stock-equipped vehicle; a heavily loaded or accessorized 4Runner may require the separately available 700 lb/in expedition coil spring (Application Note #47). This kit covers the front suspension only; rear shocks are sold separately.

Common Questions

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

Yes. ICON Application Note #18 states that this coilover system must be used with aftermarket upper control arms. Stock upper control arms are not compatible. ICON offers both tubular and billet upper control arm kits for the 1996–2002 4Runner and 1996–2004 Tacoma that are sold separately and listed as compatible add-ons.

Will the remote reservoir brackets clear my aftermarket bumper?

Not necessarily. ICON Application Note #35 states that remote reservoir mounting brackets on this coilover kit may interfere with aftermarket bumper mounts and windshield washer bottles. Buyers running an aftermarket front bumper should verify clearance before ordering or consult with their installer.

What lift height will I actually get, and does vehicle weight affect it?

This front coilover kit provides 0–3 inches of lift height adjustability via the threaded coilover body. Per ICON Application Note #55, the stated heights are calibrated for a stock-equipped vehicle. A heavily loaded or accessorized 4Runner may sit lower than the indicated height; the separately available 700 lb/in expedition coil spring (Application Note #47) is recommended for heavier builds.

How does the CDCV work, and is it included?

The CDC Valve is included in this kit. It provides 10 external adjustment positions ranging from soft to hard, allowing damping to be tuned without removing or disassembling the shock. Adjustments can be made from outside the vehicle, making it practical to change settings between on-road and off-road use.

Is this kit compatible with OEM wheels and tires?

Yes, this coilover kit is compatible with OEM wheel and tire sizes. For aftermarket fitments, ICON recommends 17x8.5-inch wheels with 4.75-inch backspace, 18x9-inch wheels with 5.00-inch backspace, or 20x9-inch wheels with 5.00-inch backspace. Tires up to 33x11.25 inches are recommended; larger tires may fit but will require fender trimming and modifications.
