TRP Air Bellow

New, DAF-approved aftermarket air bellows

TRP now supplies air bellows with OE-level quality and durability for most older DAF models. Competitively priced, they are the only aftermarket types that are tested and validated by DAF Product Development.

Safer for driver and load, longer life for trucks

Heavy loads bouncing along uneven roads cause huge stresses in commercial truck axles. New trucks have specially designed air bellows that help minimize shocks and vibration. They make for a safer, more comfortable ride for drivers, and protect expensive onboard equipment and delicate loads from damage. Air bellows ensure smooth raising and lowering of lift axles, and reduce tyre wear when the vehicle is empty.

Regular inspection is needed to check whether air bellows should be replaced to prevent suspension failure. Warning signs include:
• visible damage like cracks, tears, cuts or significant wear to the rubber surface,
• air leaks, usually causing a hissing sound,
• truck sitting lower on one side with suspension looking or feeling uneven,
• increased vibration or bounce during driving.

Reverse engineered to meet original OE specifications

Generic third-party aftermarket air bellows are often used to replace the originals but that is a mistake, particularly in large fleets. The new TRP Air Bellows are instead reverse engineered to meet the specifications of the original OE types. They are designed for ultimate vehicle safety, and lengthen vehicle life by dampening the impact of rough roads on truck and cargo.

OE and TRP are not exactly the same, but TRP is reverse engineered to come close to the OE specs.
