ICON V.S. 2.5 Aluminum Series Rear Piggyback Shocks for 2018-2023 Jeep Wrangler JL

The ICON V.S. 2.5 Aluminum Series Rear Shock Absorbers are a vehicle-specific piggyback-reservoir shock pair built for 2018–2023 Jeep Wrangler JL applications running 2.5–3 inches of rear lift over stock. Each shock is length- and damping-tuned specifically for this Wrangler JL application, and the pair ships with PTFE-lined spherical bearings and application-specific mounting hardware included.

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.

Bump Zone Technology Prevents Harsh Bottom-Outs

A 6061 billet aluminum manifold positioned a few inches below the top cap creates an internal Bump Zone that generates an additional 20% of damping force as the shock approaches full compression. For Wrangler JL owners who push hard on rocky trails or high-speed desert runs, that extra resistance at the end of the stroke is the difference between a controlled landing and a jarring bottom-out that stresses the chassis and fatigues the driver.

10-Level CDC Valve Lets You Tune on the Trail

The externally adjustable CDC (Compression Damping Control) Valve restricts oil flow into the piggyback reservoir across 10 distinct levels, all accessible with a turn of a knob (no disassembly required). Dialing in a softer setting for highway miles and firming up for off-camber rock work takes seconds, so the shocks work with the terrain rather than against it.

Aluminum Construction Manages Heat and Resists Corrosion

The one-piece impact-extruded aluminum cylinder and CNC-machined 6061 aircraft-grade aluminum components shed heat faster than steel-bodied shocks, reducing fade during prolonged off-road use. The piggyback reservoir adds fluid volume that further buffers temperature rise on extended runs. Premium-grade 5WT shock oil maintains consistent damping across a wide temperature range, so performance at the start of a trail day matches performance at the end. The aluminum finish also resists the corrosion that accumulates on shocks exposed to mud, water crossings, and road salt.

Features

• CDC Valve: externally adjustable, 10 levels of compression damping control
• Internal Bump Zone: 6061 billet aluminum manifold adds 20% damping force near full compression
• Nitrogen-charged monotube design with piggyback reservoir for improved heat dissipation
• 7/8" shock shaft: induction-hardened, chrome-plated for durability
• One-piece digressive piston with vehicle-specific valving; 100% rebuildable and revalveable
• PTFE-lined spherical bearings and application-specific mounting hardware included

Specifications

Who This Is For and Isn't

These shocks suit 2018–2023 Jeep Wrangler JL owners running 2.5–3 inches of rear lift over stock who want externally adjustable compression damping and a rebuildable, reservoir-equipped shock for mixed street and off-road use.

These shocks do not fit the 2021–2023 Jeep Wrangler Unlimited Rubicon 392. They are not compatible with stock-height or less-than-2.5-inch lift configurations, and they cover the rear position only. Front shocks require a separate purchase.

Common Questions

What Jeep Wrangler years and models do these shocks fit?

These ICON V.S. 2.5 Aluminum Series rear shocks fit 2018–2023 Jeep Wrangler JL models running 2.5–3 inches of rear lift over stock. They do not fit the 2021–2023 Wrangler Unlimited Rubicon 392.

How much lift do these shocks require?

The ICON V.S. 2.5 Aluminum Series rear shocks for the Wrangler JL are compatible with 2.5–3 inches of rear lift over stock. They are not designed for stock-height or sub-2.5-inch lift applications.

How does the CDC Valve work and what does it adjust?

The CDC (Compression Damping Control) Valve on these ICON shocks is an externally adjustable knob that restricts oil flow into the piggyback reservoir. Turning it cycles through 10 levels of compression damping force, letting the driver firm up or soften the rear suspension without removing the shock.

Are these shocks rebuildable?

Yes. The ICON V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable, meaning worn seals, oil, and valving can all be serviced or changed rather than replacing the entire shock body.

What is included with this purchase?

This listing includes a pair of ICON V.S. 2.5 Aluminum Series rear shocks with piggyback reservoirs, PTFE-lined spherical bearings, and application-specific mounting hardware. Front shocks and any lift components are sold separately.

Is there a California Proposition 65 warning for this product?

Yes. California residents should be aware that these ICON shock absorbers contain chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm, per Proposition 65.
