The Firestone 518417 is a heavy-duty air spring designed to provide adjustable load support for vehicle suspension systems. This pneumatic air bag allows drivers to customize their suspension based on load conditions, helping to maintain proper ride height and vehicle level when hauling cargo or towing trailers.

Key Features:

• Durable rubber construction with reinforced internal components for long service life
• Adjustable air pressure allows customization of load support from 5 to 100 PSI

Firestone air springs are designed to work in conjunction with existing suspension systems to provide supplemental support. They help maintain proper headlight aim, reduce body roll, and improve overall ride quality when your vehicle is carrying heavy loads or towing.
