High-quality material
TRE-4004 air springs are made from thick, multilayer rubber with a wall thickness of 12 mm, resistant to:

There is no need to replace the original suspension.
The airbags fit inside the rear coil springs and can be installed in a short time. Once installed, they are virtually invisible, and the effect can be felt from the first drive.
