Pneumoballoons in the spring 75x220 butt "New Spring"

An air cushion, or air spring spring spring (over 60 sizes), is an additional suspension element installed in an existing hollow spring (suitable for all vehicles without an internal strut). Internal pressure is regulated via a valve and should not exceed 2 atm. Installing such a system allows the driver to adjust the rear load-bearing suspension to the existing load, thereby maintaining ride comfort, stability, and handling with the vehicle fully or partially loaded. In winter, ground clearance is increased for greater off-road capability.
In the production of pillows, a mixture of NATURAL rubber is used. The wall thickness on the sides is 9-12 mm in standard air springs, 14 mm in reinforced versions, at the ends of air springs 15-16 mm. Use temperature -35 ℃ +50 ℃.
