ICON V.S. 2.0 Aluminum Series Rear Shock Absorber for 2001-2026 Silverado/Sierra 2500/3500 HD 4-6" Lift

The ICON V.S. 2.0 Aluminum Series Rear Shock Absorber is a vehicle-specific monotube shock designed for 2001–2026 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks running 4–6 inches of rear lift over stock ride height. Sold individually (SKU 76535), this shock fits both the Silverado and Sierra in 2500 and 3500 HD configurations across that full model-year span.

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.

Vehicle-Specific Valving for Real-World Performance

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. For a heavy-duty truck that spends time both on pavement and on dirt, that specificity translates to a damping curve that handles highway miles without harshness and absorbs trail impacts without bottoming. Premium-grade 5WT shock oil maintains consistent damping across a wide temperature range, so performance does not degrade between a cold morning start and a long afternoon run.

Aluminum Construction Built to Dissipate Heat and Resist Corrosion

The shock body and reservoir tubing are 6063 anodized aluminum, a material that dissipates heat and resists corrosion, both relevant on a truck that sees mud, salt, and sustained off-road use. Internal components including the rod end, top cap, and internals are 6061 aluminum. The 5/8-inch chrome-plated hardened steel shaft resists corrosion and pitting at the most exposed point of the shock. Polyurethane bushings, zinc-plated sleeves, and forged steel mounting stems are sized for OE factory-type fitment, so installation does not require custom adapters.

Rebuildable and Revalveable for Long-Term Value

Every V.S. 2.0 Aluminum Series shock is 100% rebuildable and 100% revalveable. For a truck owner who changes use cases (adding weight, switching terrains, or upgrading other suspension components), revalving the existing shock is less expensive than replacing it. A nitrile rubber top-out bumper provides noise-free operation at full extension.

Specifications

Who This Is For and Isn't

This shock suits 2001–2026 Chevrolet Silverado and GMC Sierra 2500/3500 HD owners running 4–6 inches of rear lift over stock ride height who want a rebuildable, vehicle-specific monotube upgrade for mixed street and off-road use.

This shock does not fit Cab and Chassis models of the Silverado or Sierra. Lift heights listed are measured from a stock-equipped vehicle; trucks with non-stock suspension modifications may fall outside the stated compatibility range. This is a single shock absorber; a full rear replacement requires two units.

Common Questions

Which trucks does this shock fit?

The ICON V.S. 2.0 Aluminum Series Rear Shock (SKU 76535) fits 2001–2026 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks with 4–6 inches of rear lift over stock ride height. It does not fit Cab and Chassis variants of those trucks.

How many shocks come in this listing?

This listing is for one rear shock absorber. Replacing both rear shocks on a Silverado or Sierra 2500/3500 HD requires purchasing two units.

Can this shock be rebuilt or revalved later?

Yes. The ICON V.S. 2.0 Aluminum Series shock is 100% rebuildable and 100% revalveable, which means the valving can be adjusted if your use case or suspension setup changes without replacing the entire shock body.

What is the difference between the V.S. 2.0 and V.S. 2.5 Series?

The V.S. 2.0 Aluminum Series is designed for everyday street driving and weekend off-road use. ICON's V.S. 2.5 Series is intended for more extreme off-road situations where the suspension will face greater sustained abuse; it is a separate product and is not included here.

Does this shock require any special hardware for installation?

The V.S. 2.0 Aluminum Series shock uses polyurethane bushings, zinc-plated sleeves, and forged steel mounting stems sized for OE factory-type fitment on the 2500/3500 HD platform.
