ICON V.S. 2.5 Omega Bypass Rear Shocks for 2007-2018 Jeep Wrangler JK 4.5" Lift Pair

The ICON Vehicle Dynamics V.S. 2.5 Aluminum Series Omega Bypass Rear Shock Absorbers are application-specific rear shocks for 2007–2018 Jeep Wrangler JK builds running a 4.5-inch lift, sold as a pair. Built around a 2.5-inch aluminum body with a piggyback reservoir and 28-setting hand-adjustable bypass valves, these shocks are designed for drivers who want to tune compression and rebound damping precisely without tools, on the trail or in the driveway.

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.

Tunable Damping Across 28 Settings

The ICON Bypass Valve is an externally adjustable valve that restricts oil flow through the bypass tube, giving 28 detented settings at quarter-turn increments for both compression and rebound. That resolution matters because trail conditions change: a setting dialed for a loaded overlanding run differs from one suited to an empty highway drive home. Bypass tubes are replaceable in the event of damage, so a hard hit on the trail does not require replacing the entire shock body.

Internal Bump Zone for High-Speed Control

A 6061 billet aluminum manifold positioned a few inches below the top cap creates an internal Bump Zone. As the shock approaches full compression at high velocity, damping force increases significantly, reducing harsh bottom-outs during aggressive off-road use. The 7/8-inch induction-hardened, chrome-plated shock shaft and one-piece impact-extruded aluminum cylinders support that control under repeated hard use while resisting corrosion over time.

Piggyback Reservoir and Long-Term Serviceability

The piggyback reservoir increases fluid volume, which improves heat dissipation and reduces shock fade during prolonged off-road use. On extended trails where repeated compression cycles would otherwise cause a smaller shock to overheat and lose consistency, that additional volume maintains damping performance. Premium-grade 5WT shock oil maintains consistent damping across a wide temperature range. Every Omega Series shock is 100% rebuildable and 100% revalveable, meaning the shock can be serviced and revalved for a different application rather than replaced outright.

Features

• 28-Setting Bypass Valve: hand-adjustable compression and rebound tuning at quarter-turn increments, no tools required
• Internal Bump Zone: 6061 billet aluminum manifold increases damping force near full compression to reduce bottom-outs
• Piggyback Reservoir: expands fluid volume for improved heat dissipation and reduced shock fade
• 7/8" Hardened Shaft: induction-hardened, chrome-plated for durability and corrosion resistance
• Replaceable Bypass Tubes: field-serviceable in the event of damage without replacing the shock body
• Fully Rebuildable and Revalveable: PTFE-lined spherical bearings and application-specific mounting hardware included

Specifications

Who This Is For and Isn't

These shocks suit 2007–2018 Jeep Wrangler JK owners running a 4.5-inch lift who want high-resolution, tool-free damping adjustment for mixed on-road and off-road use, and who value long-term serviceability over a replace-and-discard shock.

These rear shocks are not compatible with Jeep Wrangler JL or JT models, with JK builds at lift heights other than 4.5 inches, or with front shock positions. A separate application-specific shock is required for the front. Front shocks and any additional lift components are not included.

Common Questions

What Jeep models and years do these shocks fit?

These ICON V.S. 2.5 Omega Bypass rear shocks are configured specifically for 2007–2018 Jeep Wrangler JK with a 4.5-inch lift. They are not designed for the JL (2018–present) or JT Gladiator platforms, and they are not interchangeable with front shock positions on the JK.

How do I adjust the bypass valves, and do I need tools?

The ICON Bypass Valve is hand-adjustable with no tools required. It provides 28 detented settings at quarter-turn increments, allowing the driver to increase or decrease oil flow through the bypass tube to tune compression and rebound damping to their preference.

What is the Internal Bump Zone and why does it matter?

The Internal Bump Zone is created by a 6061 billet aluminum manifold positioned a few inches below the top cap of the shock. As the shock nears full compression at high velocity, damping force increases significantly, reducing harsh bottom-outs and giving the driver more control in aggressive off-road situations.

Can these shocks be rebuilt or revalved later?

Yes. Every ICON Omega Series shock is 100% rebuildable and 100% revalveable. The bypass tubes are also individually replaceable in the event of damage, so a hard trail impact does not necessarily require replacing the entire shock body.

Is there a California Proposition 65 warning for this product?

Yes. This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm. This warning applies to California residents as required under Proposition 65.
