Key Features:

The ICON Stage 4 Suspension System incorporates premium components and innovative technology to elevate your Ram’s performance:

• 2.5-inch dual rate coil springs for improved load handling and ride comfort
• Polyurethane bumpstops to reduce harsh bottoming out and extend suspension life
• 2.5-inch V.S. Series shocks featuring FK bearings, billet top caps, and forged stems with rolled threads for exceptional strength and consistent damping
• Adjustable bearing-style track bar that enhances front axle centering and rigidity compared to factory flexible joints
• Heavy-duty tubular steel upper and lower control arms that increase strength, reduce bushing bind, and expand alignment range
• Sway bar drop brackets to maintain proper sway bar geometry and handling characteristics
• 7/8-inch shock shafts for durability under demanding off-road conditions
• Industry-exclusive forged shock stems on 2.5-inch shocks for superior reliability

Construction & Design:

ICON’s Stage 4 Suspension System is built with high-grade materials and precision engineering to withstand the rigors of off-road use while maintaining excellent on-road manners. The coil springs utilize a dual rate design, optimizing comfort and load capacity. The tubular steel control arms are fabricated for maximum strength and resistance to bending or fatigue, while the polyurethane bumpstops provide long-lasting durability compared to rubber alternatives.

The V.S. Series shocks incorporate FK bearings and billet aluminum components, ensuring smooth operation and extended service life. The adjustable track bar with bearing joints replaces the factory’s flexible rubber bushings, resulting in improved steering response and axle alignment.
