Overview
Ensure a smooth, stable ride and superior load support with the Firestone 9634 Air Spring by Automann. This reversible sleeve air spring is engineered for heavy-duty commercial vehicle applications, providing the necessary dampening to protect your cargo and chassis from road shock. Whether you are performing a suspension overhaul on the driver side or the passenger side, this unit delivers factory-level performance and long-lasting durability.
Precision Engineering: The Firestone 9634 Air Spring Advantage
The Firestone 9634 Air Spring (Automann Part # AB1DK23I-9634) features a versatile reversible sleeve design with an impressive 18.2-inch extended height and a 5.1-inch compressed height. Built with a robust 9-inch wide top plate (Plate # 3404) and a 9.75-inch wide piston (# 9550), it is designed to handle extreme load fluctuations without compromising ride quality. Note: Its high-grade rubber construction is resistant to oil, environmental debris, and ozone, ensuring consistent performance on both sides of your axle.
As we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize suspension components that prevent vehicle lean and uneven wear. This air spring is a direct professional-grade replacement for Firestone W01-358-9634, Goodyear 1R12-636, and Contitech 65361. Because air springs typically wear at the same rate, we recommend replacing them in pairs to maintain balanced suspension geometry.
