ICON V.S. 2.0 Aluminum Series Rear Shock for 1999-2004 Ford F-250/F-350 SD 4WD 8-10" Front/12" Rear Lift

The ICON V.S. 2.0 Aluminum Series rear shock (SKU 36510R) is a vehicle-specific, nitrogen-charged monotube shock absorber built for 1999–2004 Ford F-250 and F-350 Super Duty 4WD trucks running 8–10 inches of front lift and 12 inches of rear lift. It is sold as a single rear shock and is engineered with ICON's vehicle-specific valving for improved on- and off-road damping at this lift height.

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.

Nitrogen-Charged Monotube with Remote Reservoir

The V.S. 2.0 Aluminum Series uses a nitrogen-charged monotube design paired with a remote reservoir, which separates the oil and gas charges to reduce aeration and maintain consistent damping even during repeated hard hits. Premium-grade 5WT shock oil is specified for consistent suspension damping across a wide temperature range, so performance does not degrade between a cold morning trail run and a hot afternoon highway return.

Aluminum Construction for Heat Dissipation and Corrosion Resistance

The shock body and reservoir tubing are 6063 anodized aluminum, chosen for heat dissipation and corrosion resistance, both relevant on a lifted Super Duty that sees mud, water crossings, and high-load towing. The rod end, top cap, and internals are 6061 aluminum, and the 5/8-inch chrome-plated hardened steel shaft resists corrosion and surface pitting that can cause seal wear over time.

Rebuildable and Revalveable

The V.S. 2.0 Aluminum Series shock is 100% rebuildable and 100% revalveable. For a truck used in demanding off-road conditions over many years, the shock body is a long-term investment rather than a consumable. Valving can be adjusted for a different use profile, and worn internals can be replaced without buying a new unit. Polyurethane bushings, zinc-plated sleeves, and forged steel mounting stems are designed for OE-style fitment at the factory mounting points.

Features

• Vehicle-specific valving: one-piece linear/digressive piston tuned for the 1999–2004 F-250/F-350 SD 4WD at this lift range
• Nitrogen-charged monotube with remote reservoir: reduces aeration for consistent damping on and off-road
• 5/8" chrome-plated hardened steel shaft: resists corrosion and surface pitting
• 6061 aluminum rod end, top cap, and internals: strength and durability with reduced unsprung weight
• 6063 anodized aluminum body and reservoir: heat dissipation and corrosion resistance
• 100% rebuildable and 100% revalveable: serviceable for long-term use

Specifications

Who This Is For and Isn't

This shock is built for owners of 1999–2004 Ford F-250 or F-350 Super Duty 4WD trucks running 8–10 inches of front lift and 12 inches of rear lift who want a rebuildable, nitrogen-charged monotube rear shock with vehicle-specific valving for improved on- and off-road performance at that lift height.

This shock does not fit 2WD F-250/F-350 models, any model year outside 1999–2004, or lift heights other than the 8–10" front / 12" rear range specified. It is a single rear shock; a complete system or front shocks require additional components sold separately. Buyers running extreme off-road use may want to consider the ICON V.S. 2.5 Series instead.

Common Questions

Does this shock fit a 2WD F-250 or F-350?

No. The ICON V.S. 2.0 Aluminum Series rear shock (SKU 36510R) is fitment-specific to 1999–2004 Ford F-250 and F-350 Super Duty 4WD trucks only. It is not compatible with 2WD variants of those trucks.

Is this a pair of shocks or a single unit?

SKU 36510R is a single rear shock absorber. Buyers who need two rear shocks or a complete front-and-rear system will need to add the appropriate additional components separately.

What lift height is this shock designed for?

This ICON V.S. 2.0 Aluminum Series rear shock is valved and sized for 1999–2004 Ford F-250/F-350 Super Duty 4WD trucks with 8–10 inches of front lift and 12 inches of rear lift. It is not intended for use at other lift heights.

Can this shock be rebuilt or revalved?

Yes. The ICON V.S. 2.0 Aluminum Series shock is 100% rebuildable and 100% revalveable, meaning worn internals can be replaced and valving can be adjusted for a different use profile without replacing the entire shock body.

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 as required under Proposition 65.
