Product Details

Firestone Coil-Rite Air Helper Springs are engineered to enhance the ride quality and load-carrying capability of vehicles equipped with coil spring suspension. Designed to fit inside your existing coil springs, the Coil-Rite system creates a variable spring rate that levels your vehicle and improves braking response and handling, even when hauling heavy loads or navigating challenging road conditions.

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
  • Fits inside existing coil springs for easy installation
  • Operates reliably in extreme temperatures from -40°F to 180°F
  • Spring performance adjusts as easily as inflating a tire
  • Application-specific design for 2011+ GM SUVs

Whether you're towing a trailer, carrying cargo, or simply want better ride control, Coil-Rite air helper springs provide the versatility and stability your vehicle needs. The adjustable air pressure system gives you complete control over your suspension's response, ensuring optimal comfort and safety regardless of payload.

Easily found what I was looking for and easy to order

Thank You!

Excelent!

Easy as pie

Quick and hopefully get the part I need.

First time used no problems

Quick and easy checkout through Amazon. My parts were half the price of others places like Auto zone for the exact same brand and party number. They shipped the next day and took about a week to get here

A+shipping was quick, communications were quick

I just placed my order, and so far I've enjoyed my experience. The website is very easy to read, and technical assistance helped me locate my correct part. Fingers crossed it's clear sailing from here.

Autoplicity was plenty cheaper than competitors for the springs I needed. I was shopping around and left the website after beginning a transaction and they sent me a coupon for 25% off shipping if I would return and purchase from them, which was cool. Unfortunately the coupon code didn't change the price and I didn't receive 25% off, but it was still cheaper than others.
