Compliance and Safety

Air suspension components can move suddenly if the system is pressurised. Depressurise the suspension system, support the axle safely, and follow the axle or suspension OEM procedure during removal and refit. After installation, re-pressurise slowly, leak-test all air line fittings, and confirm ride height is set to the trailer specification.

Trailer Applications

BPW Air Spring Assembly D30 commonly suits BPW D30-equipped trailers used in general freight and on-highway work. It is typically fitted during suspension servicing when a leaking air bag causes ride height drop, increased compressor cycling, or uneven ride behaviour.
