Overview:

The ICON 2.5 inch Dual Rate Spring Kit is engineered specifically for Dodge Ram 2500 and 3500 4WD models from 2003 through 2013, delivering a balanced combination of ride comfort and off-road capability. Designed to level your truck’s stance front to rear, this spring system enhances ground clearance while maintaining excellent on-road manners. Featuring a dual-rate design, the springs provide a soft initial compression for smooth daily driving and a firmer secondary rate to resist bottoming out during heavy loads or aggressive off-road use.

Ideal for Ram owners seeking improved suspension performance without sacrificing towing capacity or requiring extensive modifications, this kit offers a reliable upgrade that enhances both ride quality and vehicle control.

Construction & Design:

ICON’s dual-rate springs are precision-engineered from high-quality steel and undergo a rigorous shot peening process to enhance durability and fatigue resistance. Each spring is pre-set to eliminate sagging over time, ensuring consistent ride height and performance. The dual-stage powder coat finish provides superior corrosion protection, making these springs well-suited for harsh environments and off-road conditions. The kit also includes longer urethane bump stops designed to progressively absorb impacts, protecting suspension components and improving ride comfort.

For a complete suspension upgrade, ICON recommends pairing these springs with their front shocks, available in 2.0 Aluminum Series smooth body, Remote Reservoir, or 2.5 Series Reservoir options with or without CDC (compression damping control) valves. Sway bar drop brackets included in the kit accommodate the increased suspension travel.
