This heavy-duty air spring bag is built to replace part numbers like W01-358-8813, 1R12-069, and C816000 (check the full list to make sure it fits your specific setup). It's made from super thick, high-density rubber (4.5 to 5mm) and has reinforced 4140 grade steel studs that are 25% stronger than standard – so it can handle the load and lasts. The specs: top plate width is 9 inches, piston width is 9.5 inches, extended height is 18 inches, and compressed height is 7.5 inches. It weighs about 13.4 lbs. This bag is key for your air suspension system, helping balance loads, absorb road shocks and vibrations, and giving you a smoother, more stable ride. Comes with a solid 3-year unlimited-mileage warranty for peace of mind. Keep your rig riding right.
