Description
The Air Spring Ø335 (Part No. 80131051) is a premium-quality suspension air bag designed for commercial trailers, semi-trailers, and heavy-duty transport applications. Referenced as DJ-8 / US04235B, this robust air spring is engineered to deliver reliable load support, enhanced ride comfort, and consistent suspension performance in demanding operating environments.
With a diameter of 335mm, this air spring helps maintain optimal ride height across varying load conditions, reducing vibration, absorbing road shocks, and improving overall vehicle stability. By supporting effective load distribution throughout the suspension system, it helps minimise chassis stress, reduce tyre wear, and enhance operational efficiency.
Manufactured from reinforced rubber compounds and high-strength materials, the air spring is built to withstand continuous flexing, heavy axle loads, harsh weather conditions, and the rigours of commercial transport operations. It is ideal for routine maintenance, fleet servicing, suspension refurbishment, and replacement of worn or damaged air suspension components.
