Icon Vehicle Dynamics Ford Raptor Rear Hydraulic Bumpstop System (95120)
ICON Vehicle Dynamics' Ford Raptor Rear Hydraulic Bumpstop System has been through extensive R&D, testing, and tuning before ICON could introduce a product we were confident in labeling the most comprehensive Raptor bumpstop solution on the market.
What does the bumpstop do? In short, 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. The factory rear bumpstop is made of foam rubber and is limited on how much energy it can absorb. Ford Raptors have a couple of unique issues that are problematic for proper control of bumpstop forces. The factory rear bumpstops are mounted in a manner that allows for the rubber to squish out to the side of its mount, allowing metal to metal contact. The frame surrounding the OEM bumpstop mount is not capable of these kinds of forces and with repeated abuse can lead to frame damage not covered by warranty.
The more robust solution is a hydro-pneumatic bump shock or "air bump". 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" 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.
