Commercial Vehicle Products | Chassis Mounts Bolster Springs Adapt to different load conditions and improve driving comfort and stability Bolster springs are used in walking beam suspension applications, particularly common in North America and for heavy duty applications. Being installed as a twin-axle unit, they connect the vehicle axle with the steel spring. Compared to the usual steel supports, they offer noise reduction, improved driving comfort and stability as well as protection of the steel spring from wear. The adapted design of the bolster springs offers flexible spring rates, depending on the load situation: a soft spring rate for high driving comfort when the vehicle is unladen or a stiff spring rate for high stability when laden. The bolster spring characteristics can be flexibly adapted to different empty weights and payloads, making them an ideal solution for commercial vehicles in varying operating conditions. The integrated pin limits the maximum spring deflection, resulting in high durability and reliable performance. About Chassis Mounts In the transportation industry, cargo and goods need to be delivered on the road over long distances as quickly and safely as possible without incurring damage for both the vehicle and load. Products to reduce Noise, Vibration and Harshness in commercial vehicle chassis applications need to be effective, durable and reliable as they operate under high loads and stresses. Chassis mounts for trucks, busses, tractors and trailers control vibrations and absorb shocks transmitted from the road surface into the chassis of the vehicle. more Related Products Reaction Rod Bushings Leaf Spring Bushings Axle Bump Stops Downloads Code of Conduct Documents for Customers Documents for Suppliers Imprint Data Protection Legal Notice Follow us on Contact us Jobs & Career Products & Services Suppliers & Service Providers Vibracoustic Aftermarket Our Locations Media Compliance The website uses cookies to allow for the best possible user experience.
