For such a small part in a car the Ford bump stop is perhaps the most misunderstood element within a car suspension system. Going back to when it was first introduced it was a simple block of rubber fixed to the suspension to prevent an axle or suspension moving too much when the wheel hit a pothole or bump in the road. As technology has evolved they are now commonly referred to as a spring aid as they can affect the way in which a car pitches or rolls. The air bump stops can have an impact on the balance of the car offering significant improvements.
