Truck body mounts are fasteners equipped with shock-absorbing material. They are used to attach both the cab and the bed of the truck to its frame.
The body mount serves a dual purpose of attaching the cab and frame while also absorbing the stresses of operation. The mount provides a more comfortable ride and prevents unnecessary stress to the connection provided by the fasteners. The absorbing material used can include rubber or polyurethane. Replacing stock body mounts with taller aftermarket versions is a common method to increase the height of a truck. This method often requires modification of components attached to the frame and also in the cab, such as the steering column.
