Big trailers and heavy bed cargo can make the rear of your truck sag and the front lift, which hurts braking and steering. The Firestone Ride-Rite Red Label Extreme Duty Air Helper Springs add up to 7,500 lbs of load-leveling capacity between the frame and rear suspension to keep your truck level and stable. With properly leveled ride height, your tires stay planted, your headlights stay aimed correctly, and your handling stays predictable no matter what you’re towing or hauling.
Every load is different, so being able to dial in your suspension makes all the difference. These heavy-duty air springs let you adjust air pressure anywhere from 5 psi when unloaded to 150 psi at maximum capacity. Individual inflation valves let you balance pressure side to side for uneven loads, keeping your truck steady through turns and across rough ground. Add air when you’re hitched up or loaded down; drop pressure when running light for a smoother ride.

Heavy work demands strong parts, and the RED Label springs deliver with four layers of reinforced rubber wrapped around a braided wire girdle for added strength. The double-convoluted shape increases burst pressure, while corrosion-resistant metal end plates are sealed with a rolled crimp for long-term durability. This rugged build prevents permanent sagging, reduces wear on leaf springs, and keeps your suspension working reliably under serious weight.

Getting real load support doesn’t have to be complicated. Each kit includes brackets, air springs, air line, hardware, and separate valves for manual inflation—all designed for a no-drill installation that mounts directly between the axle and frame. Route the airlines to your bumper for easy access, add optional switches or compressors later if you want in-cab control, and you’re ready to roll with a stable, level truck that handles the load right.

This set was a replacement for the ones on my F350 that were already on the truck. Everything went back together with ease once the old bracket were removed. With one air compressor air is is delivered to the air-ride system one the truck is started. I pill a fifth-wheel with a tongue weight of around 3600 pounds. With this system I'm able to level out the truck.
Install was straightforward. Instructions are pretty good and easy to follow. I paired with an onboard air compressor with wireless control which makes adjusting air pressure in the bars super convenient.
Fits perfectly on a 2021 GMC chassis c ab
I'll be putting them on once the weather cooperates!
Great customer service!
Good quality for the price. Highly recommend calling and ordering over buying online to verify correct kit needed and avoid getting charged to ship the wrong product back.
I have used e-trailer for several different products and each time has been an excellent experience. Thank you to everyone at e-trailer that helped me with my parts order.
Merry Christmas to you all, Mike Davis
This has worked out great on our 2020 1 tonn Chevy dually. Really happy with how it has performed leveling and balancing loads. Only issue we've had is one of the bags leaks slightly, and we haven't been able to stop it.
The kit looks ok. The airbags had sand on them. I hope this wasn't a returned item. Extra tape on the box. The printed page of package listing is wrong. It says you need 14 3/8-16 flange lock nuts. Actually you need 16!! So in the morning I have to go to the local hardware store and get two more. We'll see if everything works tomorrow. Fingers crossed.
Will definitely use them again.
Great product, quite complicated to install. Also needed to make modifications to brackets for fuel pump driver module and brake hose brackets. I have a lift.can’t imagine trying to do it without
Good customer service, correct part very satisfied.

Sorry it arrived to you like that, Christopher. We do not sell previously installed parts, so it likely opened in transit. Which now that I said that, probably isn't a great thing to hear either. That said, there should be absolutely nothing wrong with it and I think you will be happy with it. I can also see what you mean about needing two more nuts. I don't know why Firestone doesn't include 16 of them as you clearly need that many when counting where they all need to go in the instructions. I will be bringing this to their attention so hopefully no one else is surprised. What are you towing?
