Firestone Air Spring

Looking to replace your damaged air spring for better axle response under shifting loads? The Firestone Air Spring, also referred to as an Airide reversible sleeve type 1T15M-2, is intended for use in heavy-duty suspension systems across a variety of trailers and trucks. As part of the suspension system, it contributes to vehicle balance and load handling, especially during acceleration, braking, or uneven road conditions. The Firestone W01-358-8204’s reversible sleeve format offers more flexible movement than traditional bellows, which can reduce strain on the chassis and frame.

Headquartered in Nashville, Tennessee, Firestone Industrial Products® is a proud manufacturer of air spring and other anti-vibration solutions to heavy duty trucks, trailers, commercial vehicles, rail cars, and industrial equipment. It has come a long way since it revolutionized transportation with the introduction of the Airide™ Air Spring in 1938. Today, Firestone is more than just an air spring manufacturer—it’s a global leader and a local partner that sees solutions where others see obstacles. Both OEMs and everyday consumers trust this brand for their air suspension needs because of its unwavering commitment to quality and reliability. All Firestone parts are engineered and tested in ISO-certified facilities to ensure they meet the strictest standards and customer specifications.
