Product Details

The Firestone Ride-Rite Coil-Rite Air Helper Spring Kit is engineered to enhance the ride quality and load-carrying capability of vehicles equipped with coil spring suspension. These innovative air helper springs install inside your existing coil springs to create a variable spring rate, delivering improved leveling, handling, and braking performance even under heavy loads and challenging road conditions.

Key Features:

  • Adjustable air pressure allows you to customize spring performance for varying loads and road conditions—as easy as inflating a tire
  • Constructed from durable, elastic polyurethane for long-lasting comfort and stability
  • Supports 500-1,000 lbs. per set (not to exceed vehicle's GVWR)
  • Fits inside existing coil springs without suspension modifications
  • Temperature range: -40°F to 180°F (-40°C to 82°C)
  • Helps eliminate squat, sway, and bottoming out when towing or hauling

Whether you're hauling cargo, towing a trailer, or driving unloaded, Coil-Rite air helper springs give you the flexibility to dial in the perfect ride. Simply adjust the air pressure to match your load, and enjoy improved vehicle control, reduced body roll, and a more stable, level ride. Firestone's proven air spring technology provides the durability and performance you need for years of reliable service.
