From a suspension system perspective, the 17.5 square spring drum axle with double springs and reinforced design provides improved stability against both lateral and longitudinal loads. The E distance is 140 mm, the F value is 130 mm, and the reinforcement component thickness ranges from 35 to 87 mm.

In addition, the air spring bracket positioning and precise dimensional calculations for both unloaded and air-sprung loaded conditions ensure easier installation and extended component lifespan. Thanks to these features, this product is a suitable option for applications that require high safety, greater durability, and reliable performance under heavy-duty operating conditions.
