2013–2018 Ram 3500 / 2014–2018 Ram 2500 4WD
214201
Overview:
The ICON 4.5" Front Dual Rate Spring Kit is engineered specifically for the Ram 3500 (2013–2018) and Ram 2500 (2014–2018) 4WD models, delivering a perfect balance of ride comfort and rugged performance. Designed to provide a 4.5-inch front lift, this dual rate spring system enhances wheel travel and suspension articulation without compromising towing capacity or requiring drive shaft modifications. Ideal for drivers seeking improved off-road capability alongside daily drivability, the ICON springs offer a smooth initial ride with a progressive second rate that helps prevent bottoming out on rough terrain.
Built to complement ICON’s shock absorbers, this spring kit ensures optimized suspension dynamics for both on-road stability and off-road control. Whether navigating rocky trails or hauling heavy loads, the ICON dual rate springs maintain vehicle composure and reduce body roll compared to stock suspension setups.
Key Features:
This ICON spring kit incorporates advanced engineering and durable materials to deliver reliable performance and longevity:
- 4.5-inch front lift for increased ground clearance and improved approach angles
- Dual rate design with a soft initial spring rate for comfort and a firmer secondary rate to prevent bottoming out
- Shot peened and pre-set springs to eliminate sagging and maintain consistent ride height
- Dual-stage powder coat finish for superior corrosion resistance in harsh environments
- Compatible with ICON shocks, engineered to work in harmony for balanced suspension performance
- No drive shaft modifications required, preserving factory drivetrain integrity
- Maintains original towing capacity for heavy-duty applications
- Reduces body roll compared to stock springs, enhancing vehicle stability
Construction & Design:
ICON’s 4.5-inch dual rate springs are crafted from high-grade steel and undergo a rigorous manufacturing process to ensure durability and consistent performance. The springs are shot peened to relieve internal stresses and pre-set to prevent sagging over time, which helps maintain optimal ride height and suspension geometry. The dual-stage powder coating provides a tough, corrosion-resistant finish that protects against rust and environmental damage, extending the lifespan of the springs even under demanding off-road conditions.
The dual rate design features a progressive spring rate that starts soft to absorb minor bumps and road imperfections, then transitions to a firmer rate to support heavy loads and prevent suspension bottoming during aggressive off-road maneuvers. This engineering approach delivers a refined ride quality without sacrificing capability.
Installation & Fitment:
The ICON 4.5" Front Dual Rate Spring Kit is designed for straightforward installation on Ram 3500 models from 2013 to 2018 and Ram 2500 models from 2014 to 2018 equipped with 4WD. The kit fits a wide range of trims including Big Horn, Laramie, Laramie Limited, Laramie Longhorn, Limited, Lone Star, Outdoorsman, SLT, and Tradesman. Installation does not require any drive shaft modifications, making it a direct bolt-on upgrade that preserves factory driveline components and towing capabilities.
Professional installation is recommended to ensure proper alignment and suspension tuning, especially when paired with ICON shocks for optimal performance.
