SR4549

Overview:

The KYB Truck-Plus Coilovers SR4549 are engineered specifically for the 2009–2010 Dodge Ram 1500, delivering a significant upgrade in suspension performance and durability. Designed to meet the demands of modern 1/2 ton trucks, these monotube shock coilovers enhance handling, control, and ride comfort, especially when your Ram is subjected to heavy loads, off-road conditions, or fitted with larger tires and wheels. Whether you tow, haul, or simply want improved driving dynamics, the Truck-Plus Coilovers provide a reliable and robust solution tailored to your truck’s needs.

Unlike standard twin-tube struts, KYB’s Truck-Plus Coilovers utilize advanced damping technology and high-quality materials to restore and improve steering response and vehicle stability. This upgrade ensures your Dodge Ram 1500 maintains confidence-inspiring control in a variety of driving scenarios.

Key Features:

KYB Truck-Plus Coilovers combine innovative design with durable construction to deliver superior performance. Key features include:

• Monotube Design: Features two separate chambers—an air-free hydraulic chamber for precise fluid control and a high-pressure nitrogen gas chamber with a floating piston for instant damping response.
• High-Carbon Steel Coil Springs: Heat-treated and stress-relieved springs provide exceptional durability and consistent performance under heavy loads.
• Pre-Assembled Unit: Comes fully assembled with the correct spring, top mount, and insulators for quick, hassle-free installation.
• Tailored Damping Solutions: KYB selects the ideal base unit (HD Excel-G, Gas-a-Just monotube, or MonoMax) to match your truck’s specific suspension requirements.
• Supports Larger Wheels: Designed to handle aftermarket wheels adding up to 25 pounds per corner, offering improved damping over original equipment.
• Enhanced Steering Response: Specially engineered shock valves restore the precise steering feel your Ram was built to deliver.
• Robust Construction: Built to withstand off-road rigors, towing, and heavy payloads without compromising ride quality.

Construction & Design:

The KYB Truck-Plus Coilovers are crafted with durability and performance in mind. The monotube shock design separates hydraulic fluid and nitrogen gas with a floating piston, eliminating aeration and ensuring consistent damping under demanding conditions. The coil springs are made from high-carbon steel, heat-treated for strength and stress-relieved through rigorous cycle testing to maintain their shape and performance over time.

Each coilover is assembled with precision, including the correct spring rate, top mount, and insulators, ensuring a perfect fit and function right out of the box. This robust construction is ideal for trucks that face heavy loads, rough terrain, or upgraded suspension components.

As a complete pre-assembled unit, installation is straightforward and can typically be completed with standard hand tools, minimizing downtime.
