Firestone Air Suspension Spring Hardware Kits: Engineered by the Inventors of the Air Spring
When it comes to air suspension, few names carry the authority of Firestone. Firestone is trusted as the world's leading supplier of air springs — and they patented them in 1938. That eight-decade legacy of innovation is baked into every component the brand produces, including its Air Suspension Spring Hardware Kits — the fasteners, brackets, air line fittings, and mounting hardware that hold a complete air spring system together and keep it performing reliably mile after mile.
What Makes Firestone Hardware Kits Stand Apart
Firestone's air suspension hardware doesn't exist in a vacuum — it's purpose-engineered to complement the brand's flagship spring lines. Firestone Ride-Rite kits arrive prepped and ready for a fast install, and include air springs, hardware, brackets, air line, and valves for manual inflation. That means every nut, bracket, and fitting is designed and validated as part of a system, not sourced as an afterthought. Ride-Rite kits are designed for many different vehicle applications, including light- and heavy-duty trucks, SUVs, and RVs with leaf-spring suspensions.
The hardware included in these kits is selected to meet the same rigorous standards applied to the springs themselves. Firestone's rigorous testing, commercial-grade materials, and adherence to strict local and global standards are key reasons why commercial vehicle OEMs, automotive OEMs, and everyday drivers worldwide select Firestone as a suspension partner. For those tackling demanding towing or hauling duties, that commitment to material quality is what separates a system that lasts from one that rattles loose under load.
No-Drill Design and Fast Installation
One of the most practical advantages of Firestone's hardware kits is how they're engineered for installation efficiency. Most Ride-Rite kits are no-drill, meaning they utilize the factory holes and can be installed in half the time or less. Installation typically takes one to two hours. The hardware is pre-matched to the spring components and vehicle application, removing guesswork from the process and reducing the likelihood of mismatched or incompatible fasteners.
Built for Trucks That Work
Firestone's Ride-Rite and Coil-Rite Air Bag Helper Springs provide vehicle load support with air pressure that can be adjusted based on your changing needs. The spring hardware kits support both product families, ensuring stable mounting regardless of whether the application involves a leaf-spring truck, a coil-spring SUV, or a heavy-duty RV chassis. The durability of Firestone air springs is such that they will often outlast other maintenance items on your suspension, such as bushings, shocks, leveling valves, or regulators. Properly installed hardware plays a direct role in achieving that longevity — a loose bracket or an undersized fitting can compromise the entire system.
A Legacy Behind Every Bolt
Firestone Airide is part of the Bridgestone family and shares its heritage with Firestone Tire & Rubber Company. Today, Firestone Airide focuses specifically on air spring and suspension technologies used in automotive, commercial transportation, and industrial equipment applications. That focus means the hardware kits available here aren't generic — they reflect decades of suspension-specific engineering refined through OEM partnerships and real-world field performance. For any driver who depends on their vehicle's payload capacity and ride stability, choosing Firestone means trusting the brand that built the standard.
