Assemblies, systems, devices, and methods for disassembling an original equipment manufacturer (OEM) air shocks/air springs and replacing the inflatable bag/bladders and adding a crimp ring adapter to a top mount in order to reassemble and remanufacture the air shock/air spring with a new inflatable bag/bladder as an effective high quality and good reliability OEM replacement part. The existing air bladder is substantially cut out form the OEM air shocks/air springs, leaving a portion of the existing air bladder left inside of the remanufactured air shock/air spring.

A gas spring system (10), comprising: an end plate (12); a piston (14) laterally spaced from said end plate (12); a first flexible sleeve (16) having a first end (13) and a second end (15), said first end (13) of the first flexible sleeve (16) sealingly connected to the end plate (12); a second flexible sleeve (18) having a first end (17) and a second end (19), said first end (17) of the second flexible sleeve (18) sealingly connected to the piston (14); and a swage assembly (20) sealingly engaging the respective second ends (15, 19) of said first and second flexible sleeves (16, 18).

A support ring used as part of an air spring assembly, where the support ring provides support for a top cap against radial forces applied by a clamping ring. The support ring is made of a plastic material which is less costly than a metal support ring. The plastic material is a high creep resistance plastic material, which provides increased strength and improved creep resistance, to withstand the compressive radial forces of the clamping ring. Once the support ring is formed, the top cap, which is also made of plastic, is overmolded such that a portion of the top cap is overmolded around the support ring. The high creep resistance plastic material is oriented during the injection molding process around the entire circumference of the support ring, to provide sufficient strength to withstand the radial forces from the clamping ring.
