ICON V.S. 2.0 Aluminum Series Rear Shock for 2025-2026 Toyota 4Runner 0-3" Lift

The ICON V.S. 2.0 Aluminum Series Rear Shock Absorber is a vehicle-specific, nitrogen-charged monotube shock built for 2025–2026 Toyota 4Runner owners running 0–3 inches of rear lift over stock. Sold individually; two are required per vehicle. This shock is not compatible with Adaptive Variable Suspension (AVS) equipped 4Runners.

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.

Tuned for the 4Runner, Not Adapted from a Universal Fit

ICON engineers valve each V.S. 2.0 shock specifically for the weight, geometry, and suspension travel of the target vehicle rather than applying a generic tune. The one-piece linear/digressive piston delivers a damping curve matched to how the 2025–2026 4Runner platform moves on pavement and on trail, not a compromise between a dozen different applications.

Aluminum Construction That Manages Heat and Resists Corrosion

The 6063 anodized aluminum body and reservoir tubing shed heat faster than steel-bodied shocks, which matters on long descents or repeated off-road cycles where fluid temperature climbs and damping consistency drops. The 6061 aluminum rod end, top cap, and internals keep unsprung weight in check while maintaining structural strength. Premium 5WT shock oil holds consistent damping across a wide temperature range, so performance on a cold morning trail run and a hot desert run stays predictable.

Built to Be Serviced, Not Replaced

The V.S. 2.0 is fully rebuildable and re-tunable, so when valving needs adjustment for a heavier load or a different use case, the shock goes back to ICON's service department rather than into a bin. The 5/8" chrome-plated hardened steel shaft resists corrosion and pitting, and the included rubber dust boot protects the shaft between service intervals. Polyurethane bushings, zinc-plated sleeves, and forged steel mounting stems are designed for OE factory-type fitment on the 4Runner's existing mounting points.

Features

• Nitrogen-charged monotube with internal reservoir: consistent damping and reduced fade under repeated compression cycles
• One-piece linear/digressive piston: vehicle-specific valving for on- and off-road performance
• 5/8" chrome-plated hardened steel shaft: resists corrosion and pitting
• 6061 aluminum rod end, top cap, and internals: strength with reduced weight
• 6063 anodized aluminum body and reservoir: heat dissipation and corrosion resistance
• Fully rebuildable and re-tunable: serviceable for long-term use and valving changes

Specifications

Who This Is For and Isn't

The ICON V.S. 2.0 Aluminum Series Rear Shock suits 2025–2026 Toyota 4Runner owners running 0–3 inches of rear lift who want a rebuildable, vehicle-specific monotube shock with improved on- and off-road damping over the factory unit.

This shock does not fit 4Runners equipped with Adaptive Variable Suspension (AVS). It is not designed for rear lift heights above 3 inches over stock on the 2025–2026 4Runner. Buyers needing greater performance headroom for extreme off-road use should consider the ICON V.S. 2.5 Aluminum Series.

Common Questions

How many shocks does one listing include?

The ICON V.S. 2.0 Aluminum Series Rear Shock (SKU 56523) is sold individually. Two units are required to replace both rear shocks on a 2025–2026 Toyota 4Runner, so buyers completing a full rear replacement need to add two to cart.

Will this shock work with my 4Runner's Adaptive Variable Suspension?

No. The ICON V.S. 2.0 Aluminum Series Rear Shock is not compatible with 4Runners equipped with Adaptive Variable Suspension (AVS). Buyers should confirm their trim level does not include AVS before ordering.

What lift heights is this shock designed for?

This shock is designed for 2025–2026 Toyota 4Runner builds running 0–3 inches of rear lift over the factory stock height. The lift heights indicated assume a stock-equipped vehicle as the baseline.

Can this shock be rebuilt or revalved later?

Yes. The ICON V.S. 2.0 Aluminum Series shock is fully rebuildable and re-tunable, meaning valving can be adjusted for a different load or use case and worn internals can be replaced rather than discarding the entire unit.
