2007–2018 Jeep Wrangler JK

27745P

Overview:

The ICON 2.5 Series Rear Shocks are engineered specifically for Jeep Wrangler JK models from 2007 to 2018, delivering exceptional off-road performance combined with a smooth, controlled ride on the street. Designed with vehicle-specific valving and length, these shocks optimize suspension response for lifted Jeep Wranglers, particularly those with a 4.5" rear lift. ICON’s 2.5 Aluminum Series shocks are fully rebuildable and revalveable, allowing enthusiasts to maintain and customize their suspension setup over time for maximum durability and performance.

Ideal for Jeep owners seeking enhanced control and comfort, these shocks reduce harsh bottom-outs and improve handling during aggressive off-road maneuvers while maintaining street drivability. The unique internal “Bump Zone” technology increases damping force by 20% near full compression, providing superior suspension control in demanding conditions.

Key Features:

ICON’s 2.5 Series Rear Shocks incorporate advanced technologies and premium materials to ensure outstanding performance and longevity:

• One-piece digressive piston design with vehicle-specific valving for optimized ride quality on and off-road
• Internal “Bump Zone” created by a 6061 billet aluminum manifold increases damping force by 20% to prevent harsh bottom-outs
• One-piece impact extruded aluminum cylinders offer excellent corrosion resistance and a consistent finish
• Premium grade 5WT shock oil ensures consistent damping performance across a wide temperature range
• Remote piggyback reservoir design improves heat dissipation to reduce shock fade during prolonged use
• PTFE lined spherical bearings and application-specific mounting hardware for smooth articulation and durability
• 7/8” diameter induction hardened, chrome-plated shock shaft for strength and corrosion resistance
• Nitrogen charged monotube design with piggyback reservoir for consistent damping and improved heat management
• 6061 aircraft grade aluminum CNC machined components for precision and durability
• 100% rebuildable and 100% revalveable for long-term serviceability and tuning flexibility

Construction & Design:

ICON’s 2.5 Series Rear Shocks are crafted from high-quality materials engineered to withstand the rigors of off-road use while maintaining excellent street manners. The shock body is made from impact-extruded aluminum, providing a lightweight yet robust structure resistant to corrosion and damage. The internal components are precision CNC machined from 6061 aircraft-grade aluminum, ensuring tight tolerances and consistent performance.

The shocks feature a monotube design charged with nitrogen to reduce cavitation and maintain consistent damping under extreme conditions. The piggyback reservoir enhances heat dissipation, preventing shock fade during extended off-road runs. The inclusion of PTFE lined spherical bearings and application-specific mounting hardware ensures smooth articulation and secure fitment tailored to Jeep Wrangler JK models.

Installation & Fitment:

These ICON 2.5 Series Rear Shocks are designed as a direct fit for Jeep Wrangler JK models from 2007 through 2018, including various trims such as Rubicon, Sahara, Sport, and Unlimited variants. Installation is straightforward with no major modifications required when used with a 4.5" rear lift setup. The shocks come with all necessary mounting hardware and are engineered to bolt directly onto factory mounting points, ensuring a hassle-free upgrade.

For optimal performance, it is recommended to pair these shocks with compatible ICON front shocks and suspension components tailored to your Jeep’s lift and intended use.

What's Included:
