Bolster Spring

Bolster Spring


Bolster Spring is a rubber-bonded metal part used in vehicle suspension systems, especially in heavy-duty trucks and construction machinery. It helps to provide support and cushioning to the suspension system, reducing vibrations and improving overall ride comfort. The rubber bonding helps to absorb shocks and vibrations, while the metal component provides strength and durability.


Bolster Spring applied to the suspension system of the vehicle, the rubber suspension component has the characteristic of variable stiffness.

The adaptive design offers flexible spring rates according to the load situation.
