Product Description
The Goodyear 1R12-502 Rolling Lobe Air Spring is designed for heavy-duty truck and trailer air suspension systems, providing dependable 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 textile-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 reducing stress on suspension components and helping protect the vehicle and its cargo.
The Goodyear 1R12-502 is a replacement option for compatible SAF-Holland, Neway, and Watson & Chalin air suspension systems. It cross-references to Firestone W01-358-9921, ContiTech 64402, SAF-Holland 90557117, and several additional commercial vehicle suspension part numbers.
