Product Description
The Goodyear 1R12-603 Rolling Lobe Air Spring is designed for heavy-duty commercial truck 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 heavy-duty aluminum piston, this air spring is engineered to withstand demanding commercial vehicle operating conditions. The reinforced bellows helps absorb road shock and vibration, reducing stress on suspension components while helping protect the vehicle and its cargo.
The Goodyear 1R12-603 is commonly used in compatible Freightliner air suspension systems, including certain Airliner II configurations. It provides a replacement option for Firestone W01-358-9781, ContiTech 64266, Freightliner 681-320-0017, and several additional original equipment suspension part numbers.
