• Internal “Bump Zone” created by a 6061 billet aluminum manifold increases damping force by 20%, reducing harsh bottom outs and controlling high-velocity compression
• Externally adjustable ICON CDC Valve with 10 levels of compression damping for precise tuning
• Durable one-piece impact extruded aluminum cylinders offering excellent corrosion resistance and consistent finish
• Piggyback reservoir design enhances heat dissipation to minimize shock fade during extended use
• Premium grade 5WT shock oil ensures consistent damping performance across a wide temperature range
• Polyurethane bushings and forged steel mounting stems for OE factory-type fitment
• PTFE lined spherical bearings and application-specific mounting hardware for reliable installation
• 7/8” diameter induction hardened, chrome plated shock shaft for strength and durability
• Nitrogen charged monotube design with piggyback reservoir for superior performance and heat management
• 6061 aircraft grade aluminum CNC machined components for precision and longevity
• 100% rebuildable and revalveable for extended service life and customization

Construction & Design:

ICON’s 2.5 Series Rear Shocks are crafted from high-quality materials to withstand the rigors of off-road driving and heavy-duty applications. The shock bodies are made from impact-extruded aluminum, providing a lightweight yet highly durable structure that resists corrosion and wear. The internal components, including the billet aluminum manifold, are precision CNC machined from 6061 aircraft-grade aluminum to ensure exact tolerances and superior strength.

The monotube design is nitrogen charged to reduce cavitation and maintain consistent damping under extreme conditions. The piggyback reservoir improves heat dissipation, preventing shock fade during prolonged or aggressive use. The shock shafts are induction hardened and chrome plated, offering excellent resistance to bending and corrosion. Additionally, polyurethane bushings and forged steel mounting stems provide a secure, factory-style fitment that maintains suspension geometry and reduces unwanted movement.

Installation & Fitment:

These ICON 2.5 Series Rear Shocks are designed for direct fitment on Ram 2500 models from 2014 to 2022, including Big Horn, Laramie, Laramie Limited (2014-2015), Laramie Longhorn, Limited (2016-2022), Limited Longhorn (2021-2022), Lone Star (2014-2015, 2019-2022), Outdoorsman (2014-2016), Power Wagon, SLT (2014-2018), and Tradesman trims. Installation is straightforward with OE-style mounting hardware and requires no modifications when paired with compatible ICON suspension components.

For optimal performance, these shocks are tuned specifically for use with ICON’s .5" Lift Performance Rear Coil Springs (Part #214206). Professional installation is recommended to ensure proper torque specifications and alignment.
