Air Suspension Spring Hardware Kit

What Are Air Suspension Spring Hardware Kits?

Air suspension spring hardware kits are complete mounting and installation solution packages designed to complement or replace a vehicle's existing suspension with air-assisted support. Rather than relying solely on fixed-rate coil or leaf springs, an air suspension system uses pressurized air bags — or air springs — to dynamically support the vehicle's weight. The hardware kit component is the backbone of that system: it provides the brackets, mounting hardware, air lines, Schrader valves, and fittings needed to properly secure the air springs to your vehicle's frame and suspension.

Why Air Suspension Hardware Kits Matter

When a truck, SUV, or motorhome carries heavy cargo or tows a trailer, the factory suspension can sag, causing poor steering response, reduced brake effectiveness, uneven tire wear, and an uncomfortable ride. Air suspension spring hardware kits solve this problem by giving you the ability to fine-tune air pressure to match the load — inflate when hauling heavy, deflate when running light. The result is a level, stable vehicle whether you're carrying a full bed of materials or cruising empty.

Beyond load leveling, a properly installed air suspension system can reduce body roll and sway during towing, protect the frame and chassis from stress, and even improve the safety of your braking distance under load. For RV owners, contractors, and anyone who regularly pushes their vehicle's payload limits, a quality hardware kit ensures the air springs stay firmly and safely in place through thousands of miles of use.

What's Typically Included in a Hardware Kit

• Mounting brackets – vehicle-specific steel brackets that anchor the air springs to the frame and axle
• Air lines and fittings – durable tubing that routes pressurized air to each spring independently
• Schrader valves – inflation ports, typically accessible from the vehicle's exterior for easy pressure adjustment
• Fasteners and hardware – all bolts, clamps, and zip ties required for a complete installation
• Instruction manual – fully illustrated guides to walk you through the installation process

Firestone's Ride-Rite and Sport-Rite product lines offer application-specific hardware kits for light- and heavy-duty trucks, SUVs, and motorhomes.

Key Considerations When Shopping

Always verify that the kit you choose is designed specifically for your vehicle's year, make, model, and suspension type — leaf spring, coil spring, or otherwise. Pay close attention to the weight rating of the hardware and air springs; kits are often rated by load capacity per pair and should match or exceed your typical hauling or towing needs. Also consider whether the kit includes inflation valves positioned for easy access, and whether you may want to pair it with an onboard compressor system for even greater convenience.
