ICON 2010-14 Ford Raptor Rear Air Bump Kit | 2010-2014 Ford F-150 Raptor 2WD/4WD Gas

ICON Vehicle Dynamics Ford Raptor Rear Hydraulic Bumpstop System has been through extensive testing, and tuning before ICON could introduce a product we were confident in labeling the most comprehensive Raptor bumpstop solution on the market. A bumpstop's job is to control the final up travel of the suspension. Many Raptor owners are using their vehicles beyond their intended design and are often loaded with additional weight, which when combined results in VERY high suspension impact speeds. ICON's hydraulic bumpstop 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 bumpstop. 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 bumpstop, ICON's hydraulic bumpstop 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 bumpstop system uses a 2.5 inch 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.
