Product Details

The Firestone Ride-Rite 4150 Coil-Rite Air Helper Spring Kit delivers enhanced load support and ride quality for vehicles equipped with coil spring suspension. These innovative air helper springs install inside your existing coil springs to create a variable spring rate, allowing you to level your vehicle and improve handling and braking performance under heavy loads and challenging road conditions.

Key Features:

  • Adjustable air pressure allows customization for varying loads and road conditions
  • Constructed from durable, elastic polyurethane for long-lasting performance
  • Supports 500-1,000 lbs. per set without exceeding vehicle GVWR
  • Operates reliably in temperatures ranging from -40°F to 180°F
  • Installs inside existing coil springs without modification
  • Adjusts as easily as inflating a tire for on-demand performance tuning

Whether you're towing a trailer, hauling cargo, or navigating rough terrain, the Coil-Rite system provides the support and stability you need. The adjustable air spring technology compensates for additional weight, reducing squat and maintaining proper vehicle stance for safer driving dynamics and improved ride comfort.

Found the lowest price for FluidAmpr Pulley for my 1j. Hope its shipped to me in 2 days like it says!

weary easy

ordered 4 cans to prime/paint/clear coat some rims. paint came in 2-3 days (incredibly fast). They forgot a can, i emailed and got a reply within 20 minutes, and the can was on my doorstep the next day. im very impressed

Why shop on Ebay, when there is Autoplicity. Cheaper prices than Ebay, Faster shipping and good return policies.

Easy ordering. Bets price by far. Fast shipping.
