When you’re hauling serious weight, rear-end sag can throw off handling and braking. The Firestone Ride-Rite Air Helper Springs add up to 5,000 lbs of load-leveling capacity, working between the frame and rear suspension to keep your vehicle level and stable. By keeping the back end from squatting, steering stays sharper, braking more predictable, and headlight aim correct. It’s real support you can feel every time you hook up a camper, trailer, or load the bed full of gear.
Heavy loads don’t have to mean a rough ride. These single-convoluted rubber air springs use up to 100 psi of air pressure to absorb road shock and soften contact between axle and frame. That means fewer jolts over potholes and less bottoming out when the weight piles on. Each bag’s four layers of reinforced rubber and corrosion-resistant metal end plates deliver cushioning that keeps your suspension working smoothly under tough conditions.
Every haul is different, so being able to fine-tune support matters. With manual inflation valves for each side, you can adjust air pressure from 5 psi up to 100 psi—whether you need both sides even or one side stiffer for an off-center load. It’s an easy way to match your ride height and firmness to what you’re carrying so things stay balanced and comfortable mile after mile.
Each kit comes with air springs, brackets, hardware, air line tubing, and separate valves for manual inflation. The rolled crimp seal keeps each spring securely anchored, while corrosion-resistant parts stand up to weather and wear. The result is a suspension upgrade built for consistent performance and long-term reliability without adding strain or permanent sag to your existing suspension.
The construction material of the fittings may vary.

its been a year now and love these bags. The added stability is worth every penny. I run about 10 P.S.I. to level the load. Will put these in my next vehicles for the towing confidence they bring.
