Product Description
The Goodyear 1R12-504 Rolling Lobe Air Spring is a heavy-duty replacement suspension air bag designed for commercial trucks and trailers equipped with compatible SAF-Holland/Neway air ride suspension systems. Engineered to provide dependable suspension support, this air spring helps absorb road shock, reduce vibration, and maintain proper ride height under varying load conditions.
Featuring a durable reinforced rubber bellows and rolling-lobe design, the 1R12-504 is built to withstand the demanding operating conditions of heavy-duty trucking and trailer transportation. Its composite piston construction provides strength while reducing overall weight, and the flexible rubber bellows allow the suspension to respond effectively to changing road surfaces and vehicle loads.
The Goodyear 1R12-504 includes an internal bumper and mounting bracket for compatible suspension configurations. It provides a reliable replacement for worn, leaking, or damaged suspension air springs, helping restore proper air suspension operation, vehicle stability, and ride comfort.
