A loaded trailer or heavy cargo can make the rear sag and throw your steering and braking out of balance. Firestone Coil-Rite Air Helper Springs add up to at least 500 lbs and at most 1,000 lbs of load-leveling support to your existing rear coil springs. With adjustable air pressure from 5 psi to 35 psi, they help keep your vehicle level for better control, even load distribution, and properly aimed headlights when you’re towing or hauling.
Every trip is different, and these air springs let you dial in the right firmness for each one. By manually adjusting the air pressure—side to side if needed—you can balance off-center loads, reduce body roll, and soften road shock. The result is a smoother ride with less bottoming out when loaded and a more comfortable feel when driving empty.
Road conditions and heavy use can wear down factory suspension parts over time, but these Coil-Rite air springs are built from tough, elastic polyurethane for long-term comfort and stability. They maintain their shape under heavy loads and resist damage from repeated compression, so you get consistent performance season after season.
Installing better suspension support doesn’t have to be complicated. The Coil-Rite kit includes the air springs, brackets, hardware, air line, and separate valves for manual inflation. Everything you need for setup is in the box. Once installed inside your rear coil springs, you can easily access the inflation valves at the bumper for quick pressure adjustments whenever you load up again.

The construction material of the fittings may vary.

Really cool to hear how well the airbags have been working out for you, especially hearing your experience in the past. How's the ride day-to-day when you're not hauling that awesome camper?

Other than a slight leak in the driver’s side that is not any fault of the product, this set up has worked extremely well! I’m very happy with these air bags and would highly recommend them over the AirLift1000 bags as there’s no comparison in quality! These Ride Rite bags are worth every penny!!!

Thank you so much for taking the time to leave a review and for sharing those awesome photos! I'm really glad Jeremy was able to get everything straightened out quickly and make the exchange process easy. How are the bags working for you so far?

Good idea taking the springs off, Joel! These can definitely be a bit of a pain in the butt with all the stuff impeding an easy install. Being able to clean the area is also nice! What are you towing with your Avalanche? Or did you want these more for regular driving?

Have you tried putting a dishwashing liquid/water combo on the area where the air line joins with the bag? This will make any leaks stand out like a sore thumb. It's extremely important that the air lines are cut precisely at a 90° angle. You can't use angle cutters, because it will crush the air line and it'll always leak....

I'd make sure that the tubing that goes into the air spring's fittings are cut so they're perfectly square. That is the main culprit when it comes to leaks....

I had to take the right rear airbag and deflated it. I took a piece of mudflap about a quarter inch thick and put it on top of the airbag with a hole in the middle of the mudflap piece that gave more clearance between the car and the airbag valve. Now I have had no leaks for a year. With the least 9000 miles of towing and rough terrain.
