Firestone 4107 Ride-Rite Coil-Rite Air Helper Spring Kit

The Firestone Ride-Rite 4107 Coil-Rite® Air Helper Spring Kit is designed for vehicles with a coil spring suspension. These air helper springs fit inside the existing coil springs to create a variable spring rate, helping level the vehicle and supporting more effective braking and handling, even under heavy loads and in adverse road conditions.

Key Features:

• Installs inside existing coil springs to create a variable spring rate
• Adjustable air pressure lets you adapt to changing loads and road conditions, as easily as inflating a tire
• Helps level the vehicle and supports braking and handling under heavy loading
• Made of durable, elastic polyurethane for long-lasting comfort and stability
• Supports 500-1000 lbs. per set, not to exceed the vehicle's GVWR
• Designed to operate in temperatures from -40°F (-40°C) to 180°F (82°C)

Whether you are towing, hauling, or carrying a heavy load, Coil-Rite air helper springs give you control over your vehicle's ride height and spring performance.
