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.

You have a nice set up, Donald! I'd love to hear how your first tow goes once you can take the camper out!

A year in and still 5 stars. The ride and controll is noticable better with the air bags inflated to just 60psi when towing my 16K lb 5th wheel. I run with about 30 psi if Im hauling a lighter load and just keep 5psi in them when Im empty. I have had no issues at all with the air bags or my on board compressor. Absolutely recommend this set up.

Glad to hear the install went smooth for you Brian. Four hours isn't bad doing this solo! Also glad you got some new tools out of the deal. Let us know how these perform and if you need anything else.

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?
