Firestone 6024 Coil-Rite Air Helper Spring - Kit

The Firestone 6024 Coil-Rite Air Helper Spring Kit is an adjustable air spring system engineered to mount inside existing open coil spring suspensions, delivering a variable spring rate that significantly outperforms a standard factory coil spring. Designed for cars, minivans, vans, light trucks, SUVs, and RVs with coil spring suspension, this kit restores and maintains proper vehicle level under load while improving overall ride quality, handling, and braking effectiveness.

Built from durable, elastic polyurethane, Coil-Rite air helper springs are engineered to withstand the rigors of coil-sprung suspensions and operate reliably across an extreme temperature range of -40°F to 180°F (-40°C to 82°C). The air springs support 500–1,000 lbs per set (not to exceed vehicle GVWR), giving you the load support you need without overloading your suspension.

Adjusting the spring rate is as simple as inflating or deflating the air springs—no tools required. This allows you to fine-tune air pressure on the fly for varying loads and road conditions, keeping your vehicle level and your headlights properly aimed at all times.

Key Features:

• Installs inside existing coil springs — no cutting or drilling required
• Adjustable air pressure for on-demand tuning to match load and road conditions
• 500–1,000 lb load support per set (not to exceed vehicle GVWR)
• Durable polyurethane construction for long-lasting performance and flexibility
• Operating temperature range: -40°F to 180°F (-40°C to 82°C)
• Prevents bottoming out with a protective air cushion between axle and frame
• Maintains a level vehicle stance to improve steering balance and brake effectiveness
• Reduces uneven tire wear caused by sagging or overloaded suspension
• Keeps headlights properly aimed for safer nighttime driving under load
• Kit includes all necessary hardware, air line, and inflation valves
