Product Description
The Goodyear 1R13-109 Rolling Lobe Air Spring is designed for heavy-duty truck and trailer air suspension systems, providing reliable load support, improved ride comfort, and reduced vibration during operation. Its rolling lobe design allows the suspension to respond smoothly to changing road conditions while helping maintain proper ride height and vehicle stability.
Manufactured with a reinforced rubber bellows, durable mounting components, and a composite piston, this air spring is engineered to withstand demanding commercial vehicle operating conditions. The flexible bellows helps absorb road shock and vibration, while the integrated internal bumper provides additional protection during suspension compression.
The Goodyear 1R13-109 is commonly used in compatible Ridewell trailer suspension systems, including certain RAR-series configurations. It provides a replacement option for Firestone W01-358-8782, Ridewell 1001R13109G, ContiTech 66340, and several additional commercial vehicle suspension part numbers.
