- Bump Stop
This is made up of high density of polyurethane (PU). It can absorb a stronger impact force and protect the strut. This is different from rubber, the force bearing and bottom impact is better on this design.

The anodized surface is treat with lightweight aluminum (A6061) before sending it to the CNC process. This not a cylinder only function design, we have also added a design to circulate heat dissipation to prevent an unwanted temperature rise.
- Double Damping Piston
The main piston in the strut is for absorbing the reaction force from spring, the other one is in the plug-in nitrogen bottle for assisting with the impact on the spring.
