Compliance and Safety

Depressurise the air system before you remove the old air spring. Support the axle securely so the suspension cannot drop suddenly. Route air lines clear of moving parts and heat, then check for leaks after re-pressurising. Finally, tighten fasteners to the correct torque to avoid damaged studs or sealing faces.

Trailer Applications

Air Spring Assembly BPW Type 30K With Piston typically suits on-road freight trailers using BPW 30K air suspension. It helps maintain stable ride height under changing loads, which supports predictable handling. Timely replacement can also reduce breakdown risk from sudden air loss.
