ICON Vehicle Dynamics Finned Reservoir Upgrade Kit 10 Inch

The ICON Vehicle Dynamics Finned Reservoir Upgrade Kit is a shock-rebuild component designed for ICON 2.5 Series and 3.0 Series piggyback and remote reservoir shocks, replacing standard reservoirs with a 2.5-inch diameter, 10-inch long finned design that delivers a 115% increase in reservoir surface area for improved heat dissipation and damping consistency during extended off-road use.

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.

Better Cooling Where It Counts

The finned reservoir's 115% increase in surface area over a standard reservoir means heat generated during hard off-road use escapes faster, keeping damping fluid at a more consistent temperature. This is especially relevant for ICON CDCV, CDXS, and CDEV shocks, which generate heat in both the shock body and the reservoir simultaneously. Cooler fluid means more predictable damping response on long runs where standard reservoirs would otherwise begin to fade.

Cleaner Mount, More Durable Shell

The included billet dovetail reservoir mounting rails and clamps replace traditional hose clamps, producing a secure, free-floating appearance without the hardware clutter. The finned outer profile also adds structural rigidity to the reservoir shell itself, so the fins absorb trail debris impacts before they can deform the inner sealing surface, a failure mode that standard smooth-wall reservoirs are more vulnerable to.

Features

• Finned 2.5" x 10" reservoirs: laser-etched ICON logos; fits 2.5 Series and 3.0 Series piggyback and remote reservoir shocks
• 115% surface area increase: over standard reservoirs for faster heat dissipation
• Billet dovetail mounting rails: replace hose clamps for a clean, secure, free-floating installation
• Increased shell rigidity: finned profile resists dents and protects inner sealing surface from trail debris
• Complete hardware included: two 10" finned reservoirs, dovetail rails and clamps, reservoir seals, and all mounting hardware

Specifications

Who This Is For and Isn't

This kit suits owners of ICON 2.5 Series or 3.0 Series piggyback or remote reservoir shocks who want improved thermal performance and a cleaner reservoir mount, particularly those running ICON CDCV, CDXS, or CDEV shocks in sustained high-demand off-road conditions where heat buildup affects damping consistency. Installation is performed during a shock rebuild and specialty tooling is required; installation by a qualified shock technician is recommended.

This kit is not compatible with ICON 2.5 Series Omega Bypass Piggyback Reservoir Shocks. Owners with older ICON universal reservoir brackets will need to drill two 1/4-inch holes for proper dovetail clamp mounting; newer versions of that bracket come with the holes pre-drilled and are available separately. This kit does not include the shock absorbers themselves.

WARNING: This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm.

Common Questions

Which ICON shocks does this reservoir kit fit?

The ICON Finned Reservoir Upgrade Kit is compatible with ICON 2.5 Series and 3.0 Series piggyback and remote reservoir shocks. It is not compatible with ICON 2.5 Series Omega Bypass Piggyback Reservoir Shocks.

What is included in the kit?

Each kit includes two 10-inch finned reservoirs with laser-etched ICON logos, billet dovetail reservoir mounting rails and clamps, reservoir seals, and all hardware needed for installation during a shock rebuild.

Can this be installed at home, or does it require a shop?

Installation of the ICON Finned Reservoir Upgrade Kit is performed during a shock rebuild and requires some specialty tooling. Installation by a qualified shock technician is recommended.

Do I need to modify my existing reservoir bracket?

Older versions of the ICON universal reservoir bracket require two 1/4-inch holes to be drilled for proper mounting of the dovetail clamps. Newer versions of the bracket come with those holes pre-drilled and are available for purchase separately through ICON.

Why do finned reservoirs help with off-road performance?

The finned reservoir design provides a 115% increase in surface area over a standard reservoir, allowing heat generated during extended off-road use to dissipate more quickly. This helps the shock maintain consistent damping performance rather than fading as fluid temperature rises.
