ICON Vehicle Dynamics 2.5 Series Finned Reservoir Upgrade Kit 7.5 Inch

The ICON Vehicle Dynamics 2.5 Series Finned Reservoir Upgrade Kit (7.5" long) replaces standard reservoirs on ICON 2.5 Series and 3.0 Series piggyback and remote reservoir shocks with finned 2.5-inch-diameter reservoirs that deliver a 115% increase in surface area over stock, improving heat dissipation and damping consistency during sustained off-road use. Each kit includes two finned reservoirs, billet dovetail mounting rails and clamps, reservoir seals, and all installation hardware.

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.

Sustained Cooling Where It Counts

A 115% increase in reservoir surface area means heat generated during repeated compression cycles escapes faster, so damping force stays consistent through long descents, washboard roads, and back-to-back trail sections where standard reservoirs would begin to fade. The benefit is most pronounced on ICON CDCV, CDXS, and CDEV shocks, which generate heat in both the shock body and the reservoir simultaneously. The finned design addresses both sources by keeping the fluid temperature lower for longer.

Dovetail Rails Replace Hose Clamps

The included billet dovetail reservoir mounting rails and clamps secure each reservoir without traditional hose clamps, producing a cleaner installation and a free-floating appearance. The slightly larger outside diameter of the finned body also means the fins themselves take the first contact from rocks and trail debris, absorbing impact energy before it can reach the inner sealing surface and cause deformation that would compromise the seal.

Rigidity and Impact Resistance

The finned profile adds structural rigidity to the reservoir body, reducing the risk of denting from trail impacts. Protecting the sealing surface from deformation is especially important on remote and piggyback reservoirs that are exposed to the same terrain hazards as the shock body itself. Laser-etched ICON logos are included on each reservoir.

Features

• 115% surface area increase: finned 2.5" diameter reservoirs dissipate heat significantly faster than standard smooth-body reservoirs
• Dovetail mounting system: billet rails and clamps replace hose clamps for a cleaner, more secure installation
• Improved dent resistance: finned profile increases reservoir rigidity and absorbs rock and debris impacts before they reach the inner sealing surface
• CDCV / CDXS / CDEV optimized: especially beneficial for ICON shocks that generate heat in both the shock body and reservoir
• Complete kit: two 7.5" finned reservoirs, dovetail rails and clamps, reservoir seals, and all necessary hardware included
• Laser-etched ICON logos on each reservoir

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 to reduce heat fade during extended off-road use, eliminate hose clamps from their reservoir mounting, or improve reservoir durability against trail impacts. It is particularly well-suited for ICON CDCV, CDXS, and CDEV shock applications.

These finned reservoirs are not compatible with ICON 2.5 Series Omega Bypass Piggyback Reservoir Shocks. Installation requires a full shock rebuild and some specialty tooling; installation by a qualified shock technician is recommended. Owners of older ICON universal reservoir brackets may need to drill two 1/4" holes for proper dovetail clamp mounting. Newer versions of that bracket come with the holes pre-drilled.

Common Questions

What shocks does this kit fit?

The ICON 2.5 Series 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.

Can I install this kit without rebuilding the shock?

Installation of the finned reservoir upgrade kit requires a full shock rebuild and some specialty tooling. Installation by a qualified shock technician is recommended. This is not a bolt-on swap that can be performed without disassembling the shock.

Do I need to modify my existing reservoir bracket?

It depends on the bracket version. Older ICON universal reservoir brackets require two 1/4" holes to be drilled for proper mounting of the dovetail clamps. Newer versions of the bracket come with these holes pre-drilled. Updated brackets are available for purchase through ICON if needed.

What is included in the kit?

Each ICON 2.5 Series Finned Reservoir Upgrade Kit includes two 7.5-inch finned reservoirs (2.5" diameter), billet dovetail reservoir mounting rails and clamps, reservoir seals, and all necessary installation hardware. No additional components are required for the reservoir upgrade itself.

Does California's Proposition 65 warning apply to this product?

Yes. This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm. This warning is required for sale in California under Proposition 65.
