ICON's hydraulic bump stop uses oil and nitrogen to do two tasks: function as a spring and a shock. An internal nitrogen charge is compressed when the air bump is compressed to act as a spring, similar to the OEM bump stop. The difference is hydraulic air bumps are adjustable and can be tuned to have low impact forces at the beginning of the travel, and ramp theoretically to infinity at the end. Unlike the factory bump stop, ICON's hydraulic bump stop incorporates oil along with a damping piston internally to control the amount of energy that is returned to the suspension, reducing the vehicles tendency to kick. The oil and damping piston also control the compression of the air bump relative to speed which is important for Raptors hitting obstacles at extreme speeds. 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 bump stop 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.
