Firestone 4190 Coil-Rite Air Helper Spring Kit for Dodge Ram 1500

The Firestone 4190 Coil-Rite Air Helper Spring Kit is a comprehensive suspension enhancement system designed specifically for 2009-2013 Dodge Ram 1500 trucks equipped with rear coil springs. This innovative dual-component system combines Coil-Rite air bag helper springs with Work-Rite load assist springs to provide superior load support and leveling capability.

Unique Dual-System Design:

• Coil-Rite air bag helper springs mount inside existing factory coil springs to create a variable rate spring system
• Work-Rite urethane load assist springs mount to the frame and axle for additional support
• Constructed from durable, elastic polyurethane for long-lasting performance and comfort
• 2,000 lbs maximum load capacity to handle heavy hauling demands

Adjustable Performance:

• Easily adjust spring performance by inflating or deflating the air bags, just like inflating a tire
• Operating pressure range of 5-70 PSI allows fine-tuning for varying loads and road conditions
• Independent inflation valves enable side-to-side adjustment for balanced load distribution
• Maintains level ride height and prevents sagging when loaded

Installation and Benefits:

• Complete kit includes air springs, hardware, air line, and separate manual inflation valves
• No drilling required for installation on compatible vehicles
• Average installation time of 1-2 hours using basic hand tools
• Improves vehicle stability, steering control, and braking effectiveness
• Reduces tire wear and keeps headlights properly aimed under load
• Prevents bottoming out and eliminates trailer sway
• Backed by Firestone limited lifetime warranty on air springs

This kit is not compatible with Ram 1500 trucks equipped with factory air ride suspension. The Firestone Coil-Rite system provides an affordable, effective solution for drivers who regularly haul heavy loads or tow trailers, delivering enhanced comfort, safety, and control without permanently altering the vehicle's suspension.
