Product Details

The Firestone Coil-Rite 4170 Air Helper Spring Kit is designed to enhance the performance of vehicles equipped with coil spring suspension systems. These innovative air helper springs install inside your existing coil springs to create a variable spring rate, providing improved load support, vehicle leveling, and enhanced handling characteristics.

Key Features:

  • Adjustable air pressure allows customization for varying loads and road conditions
  • Supports 500-1,000 lbs. per set without exceeding vehicle GVWR
  • Constructed from durable, elastic polyurethane for long-lasting performance
  • Improves braking effectiveness and handling under heavy loads
  • Levels vehicle stance when carrying cargo or towing
  • Operates reliably in temperatures from -40°F to 180°F (-40°C to 82°C)
  • Simple air pressure adjustments similar to inflating a tire

Coil-Rite air helper springs provide years of enhanced comfort and stability by allowing you to dial in the perfect suspension support for your driving conditions. Whether hauling heavy cargo, towing a trailer, or navigating challenging road surfaces, these air springs deliver the adjustability and load support your vehicle needs.
