ICON V.S. 2.0 Aluminum Series Rear Shock Remote Reservoir for 2001-2026 Silverado/Sierra 2500/3500 HD

The ICON V.S. 2.0 Aluminum Series Rear Shock Absorber with Remote Reservoir is a vehicle-specific performance upgrade for 2001–2026 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks running 0–1 inch of rear lift over stock. Built around a nitrogen-charged monotube design and a 6063 anodized aluminum body, this shock is engineered to improve on- and off-road damping without sacrificing daily-driver comfort. SKU 76529R is sold as a single shock absorber.

Nitrogen Monotube With Remote Reservoir

The V.S. 2.0 Aluminum Series uses a nitrogen-charged monotube design paired with a remote reservoir to separate the oil and gas charges under hard use. That separation keeps the shock oil aerated less and the damping force more consistent whether the truck is loaded and towing on the highway or working through rough terrain. Premium 5WT shock oil maintains consistent suspension damping across a wide temperature range, so performance does not degrade on cold mornings or after extended off-road runs.

Vehicle-Specific Valving and OE-Style Fitment

ICON engineers valve each V.S. series shock for the specific vehicle application rather than using a generic tune. The one-piece linear/digressive piston delivers a damping curve matched to the Silverado and Sierra 2500/3500 HD platform, which means the truck rides and handles closer to its intended character rather than feeling over- or under-damped. Polyurethane bushings, zinc-plated sleeves, and forged steel mounting stems are sized for OE factory-type fitment, and application-specific reservoir mounting hardware is included so the reservoir mounts cleanly without fabrication.

Built to Last and Fully Serviceable

The 5/8-inch chrome-plated hardened steel shaft resists corrosion and surface pitting that shortens shock life on trucks regularly exposed to mud, salt, or gravel. The 6061 aluminum rod end, top cap, and internals reduce unsprung weight while maintaining structural strength. A 6063 anodized aluminum body and reservoir tubing dissipate heat efficiently and resist corrosion. Because the V.S. 2.0 Aluminum Series is 100% rebuildable and 100% revalveable, the shock can be serviced or retuned rather than replaced outright when wear or a change in use case demands it.

Specifications

Who This Is For and Isn't

This shock suits 2001–2026 Chevrolet Silverado and GMC Sierra 2500/3500 HD owners running stock height or up to 1 inch of rear lift who want improved on- and off-road damping with a fully rebuildable, serviceable shock. It works for daily drivers, weekend overlanders, and tow-capable builds that stay within the 0–1 inch rear lift window.

This shock does not fit Cab and Chassis model variants of the Silverado or Sierra 2500/3500 HD. It is not compatible with rear lift heights greater than 1 inch over stock; ICON's V.S. 2.5 Series is the stated alternative for more aggressive lift or more demanding off-road use. This listing is for a single rear shock; a complete rear replacement requires two units.

Common Questions

What lift height is this shock designed for?

The ICON V.S. 2.0 Aluminum Series rear shock (SKU 76529R) is compatible with 0–1 inch of rear lift over stock on 2001–2026 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks. The lift heights indicated apply to a stock-equipped vehicle; verify your current lift before ordering.

Does this shock fit Cab and Chassis models?

No. ICON's application notes explicitly state that SKU 76529R will not fit Cab and Chassis variants of the Silverado or Sierra 2500/3500 HD. Standard crew cab, double cab, and regular cab body-style trucks within the 2001–2026 model year range are the intended application.

Is this shock rebuildable, and can the valving be changed?

Yes. The ICON V.S. 2.0 Aluminum Series shock is 100% rebuildable and 100% revalveable, meaning it can be disassembled, serviced, and retuned by a qualified shop rather than replaced outright when the shock oil degrades or a different damping tune is needed.

How many shocks does this listing include?

This listing covers a single rear shock absorber. Replacing both rear shocks on a Silverado or Sierra 2500/3500 HD requires two units; add two to your cart or confirm the quantity needed for your build before ordering.

Does this shock come with reservoir mounting hardware?

Yes. Application-specific reservoir mounting hardware is included with the ICON V.S. 2.0 Aluminum Series rear shock (SKU 76529R), so the remote reservoir can be mounted without sourcing separate brackets or fabricating a custom solution.
