ICON V.S. 2.5 Aluminum Series Front Remote Reservoir Shocks for Toyota Tacoma / 4Runner / FJ Cruiser / Lexus GX470, S2 Secondary, Pair

The ICON V.S. 2.5 Aluminum Series Front Remote Reservoir Shocks (SKU 59706P) are application-specific monotube shock absorbers sold as a pair for the front axle of 2005–2023 Toyota Tacoma, 2003–2024 Toyota 4Runner, 2007–2014 Toyota FJ Cruiser, and 2003–2009 Lexus GX470. Each shock is length- and valving-tuned for the specific platform, and the set includes S2 secondary shocks. Note that completing the system also requires the ICON S2 Secondary Shock Hoop Kit and an applicable ICON LCA Skid Plate Kit or ICON LCA Kit, sold separately.

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.

Internal Bump Zone for High-Speed Compression Control

A 6061 billet aluminum manifold positioned just below the top cap creates ICON's internal Bump Zone. When the shock approaches full compression, this zone increases damping force by 20%, resisting harsh bottom-outs during high-speed off-road driving without stiffening the everyday ride. The result is more predictable suspension behavior over whoops, ledges, and sudden terrain changes where a standard shock would run out of controlled travel.

Remote Reservoir for Sustained Performance

The remote reservoir separates the oil volume from the shock body, giving heat generated during repeated compression cycles more surface area to dissipate. Reduced heat means reduced shock fade on long desert runs or extended technical trails where the suspension cycles continuously. The nitrogen-charged monotube design and premium 5WT shock oil maintain consistent damping across a wide temperature range, from cold morning starts to sustained high-output use.

Rebuildable and Field-Upgradeable Construction

Every V.S. 2.5 Aluminum Series shock is 100% rebuildable and 100% revalveable, so the unit can be serviced or retuned rather than replaced when wear or a change in use demands it. The one-piece impact-extruded aluminum cylinder resists corrosion and holds consistent tolerances. For buyers who want adjustable compression damping, these shocks can be upgraded to ICON's Compression Damping Control Valve (CDCV), sold separately.

Features

• Internal Bump Zone: 6061 billet aluminum manifold adds 20% damping force near full compression
• Remote reservoir: nitrogen-charged monotube with separate reservoir for heat dissipation and fade resistance
• Application-specific valving: length and damping tune set for each vehicle platform
• 7/8" shock shaft: induction-hardened, chrome-plated for durability
• PTFE-lined spherical bearings: with application-specific mounting hardware included
• Rebuildable and revalveable: CDCV upgrade compatible

Specifications

Who This Is For and Isn't

These shocks suit 4WD owners of 2005–2023 Toyota Tacoma, 2003–2024 Toyota 4Runner, 2007–2014 Toyota FJ Cruiser, or 2003–2009 Lexus GX470 who want application-tuned front suspension with high-speed compression control and fade resistance for off-road use. OEM wheels and tires fit; ICON Alloys 17x8.5, 18x9, and 20x9 are the recommended aftermarket wheel sizes. Tire sizes up to 33x11.50" are confirmed to fit without modification.

These shocks do not fit KDSS-equipped vehicles. They will not fit 2WD Tacoma models with 5 wheel lug studs. Completing the system requires the ICON S2 Secondary Shock Hoop Kit and an applicable ICON LCA Skid Plate Kit or ICON LCA Kit, none of which are included. These shocks are not confirmed compatible with other manufacturers' secondary shock hoops or LCA kits. Larger tires than 33x11.50" may require fender trimming and modifications.

Common Questions

Do these shocks work with KDSS-equipped 4Runner or FJ Cruiser models?

No. The ICON V.S. 2.5 Aluminum Series front shocks (SKU 59706P) are not compatible with KDSS (Kinetic Dynamic Suspension System) equipped vehicles. Buyers with KDSS should confirm compatibility with a fitment-specific ICON application before ordering.

What else is required to complete the S2 secondary shock system?

In addition to these front shocks, the system requires the ICON S2 Secondary Shock Hoop Kit and either an applicable ICON LCA Skid Plate Kit or an ICON LCA Kit, sold separately and not included with SKU 59706P. These shocks are not confirmed compatible with other manufacturers' secondary shock hoops or LCA kits.

Can these shocks be rebuilt or revalved after extended use?

Yes. The ICON V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable, meaning the internals can be serviced or retuned rather than requiring full replacement. They are also compatible with ICON's optional Compression Damping Control Valve (CDCV) upgrade, sold separately.

Will a 2WD Tacoma fit these shocks?

2WD Tacoma models with 5 wheel lug studs are not compatible with these shocks. Buyers with a 2WD Tacoma should verify their specific lug configuration before ordering SKU 59706P.

What tire and wheel sizes are confirmed to fit with these shocks installed?

OEM wheels and tires are confirmed to fit. Recommended aftermarket wheel sizes are ICON Alloys 17x8.5 with 4.75" backspace, 18x9 with 5.00" backspace, and 20x9 with 5.00" backspace. Tires up to 33x11.50" fit without modification; larger tires may require fender trimming.
