Firestone 4160 Coil-Rite Air Helper Spring Kit for Coil Suspension

The Firestone Ride-Rite 4160 Coil-Rite Air Helper Spring Kit provides enhanced load support and leveling for vehicles with coil spring suspension. These air helper springs install inside your existing coil springs to create a variable spring rate that adjusts to your vehicle's load, improving ride quality, handling, and braking performance even under heavy loads and challenging road conditions.

Key Features:

• Fits inside existing coil springs for easy integration with factory suspension
• Variable spring rate adjusts via air pressure for different load conditions
• Supports 500-1,000 lbs. per set without exceeding vehicle GVWR
• Constructed from durable, elastic polyurethane for long-lasting performance
• Adjustable air pressure allows quick customization for varying loads
• Operates reliably in temperatures from -40°F to 180°F
• Helps maintain vehicle level when towing or hauling cargo
• Improves stability and reduces body roll during cornering

The Coil-Rite system gives you on-demand adjustability as simple as inflating a tire. Whether you're hauling equipment, towing a trailer, or driving unloaded, you can dial in the perfect air pressure to optimize your suspension performance. The polyurethane construction resists wear and environmental damage, ensuring years of reliable service in all weather conditions.
