217706CP

Overview:

The ICON Performance 2.5 Series Rear Shocks are engineered specifically for the Ram 2500 models from 2014 to 2018, delivering exceptional off-road capability combined with a refined on-road ride. Designed with vehicle-specific valving and length, these shocks provide superior control and comfort whether tackling rugged trails or cruising city streets. Built for enthusiasts who demand durability and performance, ICON’s 2.5 Aluminum Series shocks are fully rebuildable and revalveable, ensuring long-term service and adaptability to changing driving conditions.

These shocks are ideal for Ram 2500 owners looking to upgrade their suspension for enhanced handling, reduced harsh bottom-outs, and improved heat dissipation during extended use. The piggyback reservoir design and advanced damping technology make them a premium choice for both daily drivers and serious off-road adventurers.

Key Features:

ICON’s 2.5 Series Rear Shocks incorporate advanced technology and premium materials to deliver unmatched performance and reliability:

• 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
• Externally adjustable ICON CDC Valve offers 10 levels of high-resolution compression damping adjustment with a simple turn of a knob
• Piggyback reservoir design enhances heat dissipation to reduce shock fade during prolonged or aggressive use
• One-piece impact extruded aluminum cylinders provide excellent corrosion resistance and a consistent finish
• 7/8” diameter induction hardened, chrome-plated shock shaft for superior strength and durability
• Nitrogen charged monotube design ensures consistent damping performance across a wide temperature range
• PTFE lined spherical bearings and application-specific mounting hardware for precise fitment and reduced wear
• 100% rebuildable and revalveable for long-term maintenance and tuning flexibility

Construction & Design:

Constructed from 6061 aircraft-grade aluminum with CNC machining, these shocks feature a robust build quality that withstands the rigors of off-road driving while maintaining a lightweight profile. The piggyback reservoir is strategically positioned to improve heat dissipation, reducing the risk of shock fade during extended or aggressive driving sessions. The shock shaft is induction hardened and chrome plated to resist corrosion and wear, ensuring longevity and consistent performance.

ICON’s unique internal manifold design creates an internal Bump Zone that adds extra damping force as the shock approaches full compression, enhancing control and preventing harsh bottom-outs. The externally adjustable CDC Valve allows drivers to fine-tune compression damping to match their driving style and terrain, making these shocks highly versatile.

Installation & Fitment:

These ICON 2.5 Series Rear Shocks are designed as direct replacements for the rear suspension of Ram 2500 models from 2014 through 2018, including Big Horn, Laramie, Laramie Limited (2014–2015), Laramie Longhorn, Limited (2016–2018), Lone Star (2014–2015), Outdoorsman (2014–2016), Power Wagon, SLT, and Tradesman trims. Installation requires no modifications, utilizing application-specific mounting hardware for a precise fit. Professional installation is recommended to ensure proper setup and adjustment of the CDC Valve for optimal performance.

What's Included:

• Pair of ICON 2.5 Series Rear Shocks with piggyback reservoirs
• Application-specific mounting hardware
• PTFE lined spherical bearings pre-installed
• Adjustment knob for ICON CDC Valve compression tuning
• Installation instructions

Ideal For:

These shocks are perfect for Ram 2500 owners who demand enhanced suspension performance for off-road adventures without sacrificing on-road comfort. Whether you’re tackling rocky trails, hauling heavy loads, or seeking improved ride quality on highways, ICON’s 2.5 Series Rear Shocks provide the durability, adjustability, and control needed for versatile driving conditions.

ICON Vehicle Dynamics builds performance suspension components for trucks and SUVs—think coilovers, shocks, lift/leveling systems, and supporting hardware engineered for hard off-road use. Their setups are designed to improve control, ride quality, and durability when you’re pushing faster over rough terrain or building a capable overland/trail rig.
