Trailer Air Suspension

Trailer airbag suspension kits

Explore Boss airbag kits and mounting hardware for selected trailer axle and chassis layouts. This collection includes kits for round axles with square chassis, square axles with square chassis, and matching mounting brackets.

Confirm fitment before ordering

Axle shape, chassis design, bracket layout and the gap at level ride height determine the correct kit. Check the individual product page before ordering; some installations require brackets to be welded to the axle and frame. If dimensions or fitment are unclear, contact Boss Air Suspension for advice.

How the kits help

When correctly matched and installed, airbag suspension can support a level ride and reduce the effect of bumps and vibration for selected trailers. Set pressure and ride height according to the product instructions. Airbags do not increase a trailer’s legal load rating, axle rating or towing capacity.
