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 that automatically adjusts to changing loads and road conditions.

Key Features:

  • Fits inside existing coil springs without replacing factory suspension components
  • Variable air pressure control allows easy adjustment for different loads and road conditions
  • Levels your vehicle when hauling cargo, towing trailers, or carrying passengers
  • Improves braking effectiveness and handling stability under heavy loads
  • Constructed from durable, elastic polyurethane for long-lasting performance
  • Supports 500-1,000 lbs per set (not to exceed vehicle GVWR)
  • Operates reliably in extreme temperatures from -40°F to 180°F
  • Adjustable spring performance as simple as inflating a tire

Firestone Coil-Rite air helper springs provide years of comfort and stability while maintaining your vehicle's factory ride quality when unloaded. This kit is ideal for pickup trucks, SUVs, and vans that frequently carry varying loads or tow trailers, offering on-demand load support without compromising everyday drivability.

Simple and quick

Good

Is been great so far I would like my order as fast as possible if you guys can

I was very happy with my shopping experience. Fast delivery time, and I couldn't be happier with the product I received!

Great price, easy checkout. Hope the rest of the experience goes well.

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.

good customer service

It was easy.

Autoplicity can not be beat on prices, handling, and shipping times! Very easy to deal with and quick to respond if you have any problems with your order! They are always looking out to save you money and get your parts fast!
