Our original product, a rubber air spring inserted into a car factory's coil spring, was created and patented in 1950. Manufacturer: Air Lift. Suspension Air Bag / Bellows. High-Burst Pressure. Reinforced With Steel Girdle Ring.
Originals lasted 20 years. They were warranted for ten. Impressive!
New ones came sooner than promised. Came with new bolts and air fittings. However the picture shows bag with the support plates I got no support plates with them. I just reused the old ones no problem.
