Our resulting dynamic system is one that is soft and compliant allowing full suspension travel at slow speeds, yet at high speeds will create very high forces to resist bottoming out. ICON's Ford Raptor hydraulic bumpstop system uses a 2.5" travel air bump allowing the shock additional distance to control energy, and does not interfere with suspension travel under normal driving conditions. The clamshell bracket design with triangulated cross braces not only gives a rigid mounting point for the air bump, it helps support a known weak part of the frame prone to failure.
