ICON V.S. 2.5 Aluminum Series Rear Piggyback Shocks for 2014-2026 Ram 2500

The ICON V.S. 2.5 Aluminum Series Rear Shock Absorbers with Piggyback Reservoir are a pair of nitrogen-charged monotube shocks built specifically for 2014–2026 Ram 2500 trucks running ICON's 2" Lift Performance Rear Coil Springs (part number 214202). Length and damping tune are set for this exact application, not adapted from a universal design.

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.

One-Piece Aluminum Construction

Each shock body is formed from a single impact-extruded aluminum cylinder rather than a welded or plated steel tube. That construction eliminates seams that can trap moisture, resists corrosion without a surface coating that can chip or flake, and produces a consistent wall thickness that keeps damping behavior predictable over the life of the shock. The result is a shock that holds up to repeated water crossings and trail debris without the surface degradation that shortens the service life of steel-bodied units.

Internal Bump Zone for High-Speed Compression Control

ICON machines a 6061 billet aluminum manifold into the shock body a few inches below the top cap. As the shock approaches full compression, this manifold activates an internal Bump Zone that adds 20% more damping force. That extra resistance absorbs the energy of high-velocity compression events (square-edged hits, whoops, sudden drops) before the suspension reaches its limit, reducing harsh bottom-outs without stiffening the everyday ride.

Rebuildable and Revalveable

Both shocks are 100% rebuildable and 100% revalveable. A worn seal or shaft can be serviced rather than replaced, and the valving can be changed if load or terrain requirements shift. The piggyback reservoir improves heat dissipation during sustained off-road use, reducing shock fade on long runs. Premium 5WT shock oil maintains consistent damping across a wide temperature range, and double-sealed Schrader caps protect the nitrogen charge from trail contamination.

Features

• 7/8" shock shaft: induction hardened and chrome plated for durability
• PTFE-lined spherical bearings: included with application-specific mounting hardware
• 100% rebuildable and revalveable: serviceable design with premium 5WT shock oil

Specifications

Who This Is For and Isn't

These shocks suit 2014–2026 Ram 2500 owners who have installed or are installing ICON's 2" Lift Performance Rear Coil Springs (part number 214202) and want a rear shock tuned in both length and damping for that exact lift height, particularly buyers who run mixed on-road and off-road terrain and want a shock they can rebuild or revalve rather than replace outright.

These shocks are not compatible with Ram 2500 trucks equipped with factory rear air ride suspension. They are tuned specifically for use with ICON 2" Lift Performance Rear Coil Springs (p/n 214202) and are not intended as a drop-in replacement for stock-height or other-lift applications. This listing covers rear shocks only; front suspension components are sold separately.

Common Questions

Which coil springs are required with these shocks?

These V.S. 2.5 Aluminum Series rear shocks are length- and damping-tuned specifically for use with ICON 2" Lift Performance Rear Coil Springs, part number 214202. ICON's application note states the two components are optimized as a pair; using a different spring or lift height may result in incorrect shock travel and damping behavior.

Will these fit a Ram 2500 with factory rear air ride?

No. ICON Application Note #105 explicitly excludes vehicles with factory rear air ride suspension. These shocks are designed for conventional coil-spring rear suspensions on 2014–2026 Ram 2500 trucks only.

What does the piggyback reservoir do?

The piggyback reservoir on these ICON 2.5 Aluminum Series shocks increases fluid volume, which improves heat dissipation during sustained off-road use. More fluid capacity means the shock oil temperature rises more slowly under repeated compression cycles, reducing the fade that can cause a shock to feel soft or inconsistent on long off-road runs.

What is the internal Bump Zone and when does it activate?

ICON's Bump Zone is created by a 6061 billet aluminum manifold machined into the shock body near the top cap. As the shock approaches full compression, fluid is forced through this manifold, generating an additional 20% of damping force. The effect is felt only near the end of the shock's travel, so it resists harsh bottom-outs without adding stiffness to normal suspension movement.

Can these shocks be rebuilt or revalved?

Yes. These ICON V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. Worn seals or shafts can be serviced, and the internal valving can be changed to suit different load or terrain requirements, extending the usable life of the shock beyond what a non-serviceable unit would allow.

Is there a California Proposition 65 warning for this product?

Yes. These ICON shock absorbers carry a California Proposition 65 warning: this product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm.
