ICON V.S. 2.0 Rear Shock for 2007-2018 Jeep JK Wrangler 4.5" Lift

The ICON Vehicle Dynamics V.S. 2.0 Aluminum Series rear shock is a vehicle-specific, nitrogen-charged monotube shock absorber engineered for 2007–2018 Jeep JK Wrangler builds running a 4.5-inch rear lift. It is sold as a single shock (SKU 26518) and is designed for drivers who want a meaningful performance upgrade over factory damping without moving to a larger-diameter shock body.

Vehicle-Specific Valving for Real-World Performance

The V.S. 2.0's one-piece linear/digressive piston carries valving tuned specifically for the JK Wrangler at 4.5 inches of rear lift, not a generic tune adapted from a universal shock. That specificity matters because damping forces that feel controlled on a stock-height Jeep can feel harsh or vague once the suspension geometry and travel change with a lift. The vehicle-specific calibration keeps the shock working in its intended range across both street driving and moderate off-road use.

Aluminum Construction Built to Dissipate Heat

The shock body and reservoir tubing are 6063 anodized aluminum, a material chosen for its heat-dissipation characteristics and corrosion resistance. Repeated compression cycles on a washboard road or a rocky trail generate heat that degrades oil viscosity and damping consistency. The aluminum body moves that heat away from the oil faster than a steel-body shock. The 6061 aluminum rod end, top cap, and internals add strength where the shock sees the highest stress without adding unnecessary weight.

Rebuildable and Revalveable

The V.S. 2.0 is 100% rebuildable and 100% revalveable, which means the shock does not become a disposal item when the seals wear or when a driving style changes. Premium 5WT shock oil maintains consistent damping across a wide temperature range, and the nitrogen-charged monotube design with internal reservoir resists aeration that causes fade during sustained off-road use. The 5/8-inch chrome-plated hardened steel shaft resists corrosion and pitting over time. Polyurethane bushings, zinc-plated sleeves, and forged steel mounting stems are designed for OE-style fitment at the factory mounting points.

Features

• Nitrogen-charged monotube with internal reservoir: resists fade during sustained compression cycles
• One-piece linear/digressive piston: vehicle-specific valving for the JK Wrangler at 4.5" rear lift
• 5/8" chrome-plated hardened steel shaft: resists corrosion and pitting
• 6063 anodized aluminum body and reservoir: heat dissipation and corrosion resistance
• 6061 aluminum rod end, top cap, and internals: strength and durability at high-stress points
• 100% rebuildable and revalveable: serviceable for the life of the vehicle

Who This Is For and Isn't

This shock suits 2007–2018 Jeep JK Wrangler owners running a 4.5-inch rear lift who want improved damping over factory shocks for a mix of street driving and moderate off-road use, and who value a rebuildable and revalveable shock they can service rather than replace.

This shock does not fit JK Wrangler builds at lift heights other than 4.5 inches, does not fit the front position, and is not designed for extreme off-road punishment. The V.S. 2.5 Series is the stated step up for that use. This listing is for one shock; a full rear replacement requires two.

Common Questions

What Jeep models and years does this shock fit?

This ICON V.S. 2.0 rear shock fits 2007–2018 Jeep JK Wrangler applications with a 4.5-inch rear lift. It is not confirmed for any other Jeep model, generation, or lift height.

Is this shock sold as a pair or a single unit?

This listing (SKU 26518) is for one rear shock. Buyers replacing both rear shocks on a JK Wrangler will need to purchase two units.

What does rebuildable and revalveable mean in practice?

A rebuildable shock can have its seals, oil, and wear components replaced rather than discarded when they wear out. A revalveable shock can have its internal piston valving changed to alter damping characteristics, which is useful when driving style or terrain changes significantly after the initial purchase.

Why does this shock use nitrogen charging?

The ICON V.S. 2.0 uses a nitrogen-charged monotube design with an internal reservoir to separate the shock oil from a gas charge. That separation resists aeration (the foaming of oil that causes damping fade) during repeated or sustained compression cycles on rough terrain.

When should I consider the V.S. 2.5 Series instead?

The V.S. 2.5 Series is the stated step up for vehicles used in extreme off-road situations that subject the suspension to extra abuse and punishment. The V.S. 2.0 is positioned for everyday street driving and weekend off-road use.
