FAQs:
  • What vehicles and equipment is the 2B12-309 air spring compatible with?
    The 2B12-309 is designed for air ride suspension systems in pickup trucks and is also widely used in lifting equipment such as cranes, lifting platforms, and hoisting systems. It has cross-reference compatibility with numerous OEM part numbers from manufacturers including Firestone (W01-358-7400), ContiTech (FD330-22 313), GMC (693230), Freightliner, and Volvo, among others.
  • How does this air spring improve safety and performance in lifting applications?
    In lifting equipment, the air spring provides smooth load engagement by compressing gradually to reduce sudden shocks, effectively isolates vibration from motors and uneven loads to protect components, and allows for height and level control via air pressure adjustment. This controlled motion enhances machine stability, reduces load swing, and lowers operator fatigue, contributing significantly to operational safety.
  • What are the key technical specifications for mounting the 2B12-309 air spring?
    The top cover plate has a diameter of 231mm with one 1/4 NPTF air connection hole and two 3/8-16UNC threaded holes spaced 157mm apart. The bottom cover plate also has a 231mm diameter with two 3/8-16UNC threaded holes at the same 157mm center distance. The air spring itself has a maximum outer diameter of 325mm, with extension and compression heights of 305mm and 104mm respectively, and includes a built-in buffer block.
