10-14 FORD RAPTOR STAGE 2 SUSPENSION SYSTEM
Considering the capability of our high performance 3.0 shocks, many Raptor owners are still using their vehicles beyond Fords intended design requiring further performance upgrades. These trucks are often loaded with additional weight, which when combined, results in VERY high suspension impact speeds. The factory rear bump stop 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 bump stop forces. The factory rear bump stops 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 bump stop mount is not capable of these kinds of forces and with repeated abuse can lead to frame damage not covered by warranty. A more robust solution is a hydro-pneumatic bump shock or "air bump".
