ICON V.S. 2.5 Aluminum Series Front Shocks Remote Reservoir for 2023-2026 Ford F-250/F-350 Super Duty 4WD 4.5" Lift Pair

The ICON V.S. 2.5 Aluminum Series Front Shocks with Remote Reservoir are a vehicle-specific pair built for 2023–2026 Ford F-250/F-350 Super Duty 4WD trucks running 4.5 inches of front lift, delivering a nitrogen-charged monotube design with a remote reservoir in a one-piece impact-extruded aluminum cylinder. These shocks are optimized in both length and damping tune for this exact Super Duty application, and they are compatible with 4–6 inches of front lift on non-Tremor models and 3–5 inches on Tremor-equipped trucks.

Aluminum Construction That Resists Heat and Corrosion

The one-piece impact-extruded aluminum cylinder is lighter than a traditional plated steel cylinder and provides more uniform corrosion resistance across the full shock body, a meaningful advantage on a truck that sees mud, salt, and standing water regularly. The remote reservoir increases shock oil volume and heat-dissipation surface area, which directly reduces the risk of cavitation and damper fade during sustained hard use on rough terrain. Keeping the oil cooler means the damping curve stays consistent from the first mile of a trail to the last.

Bump Zone Damping for High-Speed Compression Control

A 6061 billet aluminum manifold positioned below the top cap creates what ICON calls an internal Bump Zone. When the shock compresses at high velocity, this zone generates an additional 20% of damping force, helping prevent harsh bottom-out and keeping the suspension controlled under the sudden, repeated impacts that loaded Super Duty trucks encounter off-road. The one-piece digressive piston carries vehicle-specific valving, and premium-grade 5WT shock oil maintains consistent damping across a wide temperature range.

Built to Be Serviced, Not Replaced

These shocks are 100% rebuildable and 100% revalveable, which matters on a work or expedition truck where suspension components take real punishment over time. The 7/8-inch induction-hardened, chrome-plated shock shaft resists wear and bending. PTFE-lined spherical bearings, polyurethane bushings, and forged steel mounting stems are designed for OE-style fitment, so installation follows a familiar pattern and the hardware holds up through repeated service cycles.

Features

• Nitrogen-charged monotube with remote reservoir: resists cavitation and damper fade during extended off-road use
• One-piece impact-extruded aluminum cylinder: lighter weight, improved corrosion resistance, and consistent finish vs. plated steel
• 6061 billet aluminum Bump Zone manifold: adds 20% damping force at high-velocity compression to prevent harsh bottom-out
• Vehicle-specific length and damping tune: configured for 2023–2026 F-250/F-350 Super Duty 4WD at 4.5" lift
• 7/8" induction-hardened, chrome-plated shaft: with PTFE-lined spherical bearings and polyurethane bushings for OE-type fitment
• 100% rebuildable and revalveable: premium 5WT shock oil, fully serviceable design

Specifications

Who This Is For and Isn't

These shocks suit 2023–2026 Ford F-250/F-350 Super Duty 4WD owners running 4–6 inches of front lift (non-Tremor) or 3–5 inches (Tremor) who want a rebuildable, remote-reservoir shock with vehicle-specific damping tuning for combined street and off-road use. They can also serve as secondary shocks in the OE location when paired with ICON 4–6-inch lift coilover conversions (part 611003 also required).

These shocks do not fit 2WD Super Duty models, Super Duty trucks equipped with the Tremor package running more than 5 inches of front lift, or any Super Duty outside the 2023–2026 model years. They are not compatible with the Tremor package at 4–6 inches of lift. Buyers seeking adjustable compression damping should consider ICON's Compression Damping Control Valve (CDCV) shocks instead.

Common Questions

Do these shocks fit my 2023–2026 Super Duty with the Tremor package?

The ICON 67811P front shocks are compatible with Tremor-equipped 2023–2026 Ford F-250/F-350 Super Duty 4WD trucks running 3–5 inches of front lift over stock. They are not compatible with Tremor models at 4–6 inches of lift; that range applies only to non-Tremor Super Duty 4WD trucks.

What lift height are these shocks optimized for?

The ICON V.S. 2.5 Aluminum Series front shocks (67811P) are optimized in length for pairing with ICON 4.5-inch lift coil springs on 2023–2026 Ford F-250/F-350 Super Duty 4WD. They are compatible across a range of 4–6 inches of front lift on non-Tremor models and 3–5 inches on Tremor models.

Can these be used as secondary shocks with a coilover conversion?

Yes. The ICON 67811P shocks can be installed as secondary shocks in the OE location when used with ICON 4–6-inch lift coilover conversions. Part number 611003 is also required for that configuration and is sold separately.

Are these shocks rebuildable?

The ICON V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. The fully serviceable design means damping can be retuned and wear components replaced over the life of the shock rather than replacing the entire unit.

What is the Bump Zone, and why does it matter?

The Bump Zone is created by a 6061 billet aluminum manifold positioned below the top cap of the shock. When the suspension compresses at high velocity, this zone generates an additional 20% of damping force, which helps prevent harsh bottom-out and keeps a loaded Super Duty controlled over sudden, repeated impacts off-road.

Is there a California Proposition 65 warning for this product?

Yes. This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm. This warning applies to California residents under Proposition 65.
