TRU specialist notes

From the Trucks R Us fitment and install team, beyond the manufacturer's information.

  • Plan for a professional wheel alignment after installing any lift or leveling kit.
  • Going to bigger tires as well? Speedometer recalibration may be needed, and some tire and wheel combinations need trimming. Check the recommended wheels and tires, or ask us before you order.

    Overview

    ICON's 2014-2026 Ram 2500 4WD 2.5” Stage 5 Suspension System is made up of dual rate front coil springs, necessary bracketry and hardware, front and rear adjustable track bars, as well as 2.5 Aluminum Series reservoir front and rear shocks with CDEV. This system improves ride quality and performance both on and off-road. The ICON stage 4 system is great for towing, rough construction site terrains, and country dirt roads all while keeping a smooth highway feel. ICON 2.5" reservoir shocks with CDEV ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during heavy use. Focus on driving and let ICON Intelligent Control (IIC) read the terrain and make near-instant adjustments via the Compression Damping Electronic Valve (CDEV) at each individual shock. Control the system wirelessly through the IIC app on your phone and once configured the system functions without driver input. An adjustable track bar with FK bearings is used to not only improve rigidity over the flexible factory joints, but offer adjustability to center the front axle under the truck. With the endless hours ICON has spent testing and tuning our suspension components and shocks as a complete package, you can rest assured you have the best suspension solution on the market.

    This system includes triple-rate rear coil springs for a more compliant ride. The lighter initial rate of these performance rear coil springs helps the truck feel smoother and more controlled over washboard roads, small whoops, or similar terrain. The secondary ride rate allows the truck to maintain exceptional ride quality, while the aggressive third overload rate helps prevent bottom outs and provides payload support (at a reduced ride height). These performance systems were specifically developed for the 3/4 ton truck enthusiast who enjoys aggressive off-road adventures and does not tow or haul heavy loads.
