Buses & trucks
Developed for buses and trucks, the K40 series combines controlled damping with robust construction engineered for demanding daily operation. Building on the proven K100-40 platform, it addresses the priorities of vehicle manufacturers, fleet operators and drivers alike: stable vehicle dynamics, dependable performance and consistent ride comfort.
The K40 features a purpose-designed closure and sealing system engineered to accommodate lateral piston-rod movement while maintaining reliable sealing performance. By reducing the risk of contaminant ingress, the system helps protect internal components and preserve consistent damping throughout extended service.
Every K40 shock absorber can be overhauled and returned to service, extending its useful life and reducing the need for replacement units.
Key features
- Broad damping-force adjustment range
- Independent adjustment in both damping directions
- Designed for overhaul and return to service
- No metal-to-metal contact between friction elements
- Increased oil volume for improved thermal stability
- Purpose-designed closure and sealing system
- KARSUS valve technology for application-specific damping
The increased oil volume helps moderate temperature rise during prolonged operation, while the dedicated sealing system protects the internal mechanism against contamination. Together, these features support consistent damping and dependable performance throughout demanding service cycles.
