ICON 2.5 Series Front Coilover Kit with Remote Reservoir and CDCV for 2025-2026 Toyota 4Runner 2WD

The ICON Vehicle Dynamics 2.5 Series Front Coilover Kit with Remote Reservoir and CDCV is a vehicle-specific front suspension upgrade for the 2025–2026 Toyota 4Runner 2WD, delivering 1.25–3" of lift height adjustability and 10 settings of external compression damping control. This kit fits 2WD models only and is not compatible with Adaptive Variable Suspension (AVS) equipped vehicles.

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.

Maximum Travel from a 2WD-Optimized Shock Length

ICON engineers the shock extended length specifically for 2WD 4Runner geometry, which means the coilover reaches the full range of suspension travel the chassis allows rather than being adapted from a shared platform. For a buyer who wants to run 33-inch tires and push the front suspension hard on rough terrain, that optimized length translates directly into more wheel travel and better ground clearance without the compromise of a generic fitment.

Remote Reservoir and CDCV for Consistent Performance Under Hard Use

The remote reservoir increases shock oil volume and heat-dissipation surface area, reducing the risk of cavitation and damper fade during sustained off-road use. Damper fade shows up as a suddenly harsh or unpredictable ride mid-trail, and the added thermal capacity of the remote reservoir works against it. ICON's Compression Damping Control Valve (CDCV) adds 10 externally adjustable compression settings, letting the driver tune the front end for street commuting, slow technical crawling, or high-speed desert running without removing the shock or changing any internal components.

Aircraft-Grade Aluminum and Rebuildable Construction

The 2.5" shock body is CAD-plated for corrosion resistance and carries a 7/8" diameter shaft. CNC-machined components are made from 6061 aircraft-grade aluminum. FK rod end bearings reduce deflection and extend service life. The kit is fully rebuildable and re-tunable, keeping long-term service costs lower than a sealed unit.

Features

• Vehicle-specific valving: tuned for the 2025–2026 Toyota 4Runner 2WD front suspension
• 1.25–3" lift adjustability: height set at the coilover perch; based on gasoline-engine, stock-weight vehicles
• 2.5" shock body with remote reservoir: increased oil volume and heat capacity for fade resistance
• 10-position CDCV: external compression damping adjustment with no disassembly required
• 6061 aircraft-grade aluminum CNC components: CAD-plated shock body, 7/8" shaft, FK rod end bearings
• Fully rebuildable and re-tunable: serviceable in the field or at a shop

Specifications

Who This Is For and Isn't

This kit suits 2025–2026 Toyota 4Runner owners on the 2WD platform who want 1.25–3" of lift, a tunable compression damping system, and a front coilover built for both daily driving and demanding off-road use. It pairs with ICON's 2.5 Aluminum Series CDCV rear shocks for a balanced front-to-rear system.

This kit does not fit 4WD 4Runner models. Installation on a 4WD vehicle will damage the front axles. It is not compatible with Adaptive Variable Suspension (AVS) equipped vehicles. Advanced Driver Assistance Systems (ADAS) require recalibration after installation. Above 2" of lift, ICON Delta Joint Pro front upper control arms are recommended to maintain proper wheel alignment; those arms are not included in this kit.

Common Questions

Will this kit fit a 4WD 4Runner?

No. The ICON 2.5 Series Front Coilover Kit with CDCV is engineered exclusively for 2025–2026 Toyota 4Runner 2WD models. Installing this kit on a 4WD vehicle will result in damage to the front axles and is not supported.

Is this kit compatible with the Adaptive Variable Suspension (AVS) system?

No. This coilover kit is not compatible with 4Runner models equipped with Adaptive Variable Suspension (AVS). Buyers should confirm their vehicle's suspension configuration before ordering.

Does installation require any additional parts above 2" of lift?

Above 2" of lift, ICON recommends pairing this front coilover kit with ICON Delta Joint Pro front upper control arms to maintain proper wheel alignment. Those control arms are sold separately and are not included in this kit.

Does this kit require any recalibration after installation?

Yes. Advanced Driver Assistance Systems (ADAS) require recalibration after installing this coilover kit. This step should be performed by a qualified technician to ensure all safety systems function correctly.

How many damping adjustment settings does the CDCV provide?

The ICON Compression Damping Control Valve (CDCV) on this front coilover kit provides 10 positions of external compression damping adjustment, accessible without removing or disassembling the shock.

What wheel and tire sizes are recommended with this kit?

For aftermarket wheels, ICON recommends a 17x8.5 with 6.32" backspace and 40mm offset, or an ICON Alloys 18x9 with 6.6" backspace and 40mm offset. The recommended aftermarket tire size is 33" x 11.50"; larger tires may fit but will require fender trimming and modifications.
