Abstract

See full text

Load stabilizing inserts for a motor vehicle. The inserts include a base plate, a top plate spaced apart from and angularly pivotable with respect to the base plate, and one or more contact plates. The insert is sized and shaped for insertion between an overload spring and a spring pack in a motor vehicle such as a pickup truck. Four load stabilizing inserts may be installed to provide stable operation of the pickup truck when loaded at or near the maximum design gross operating weight of the vehicle. During those periods when the truck is not loaded, such as when a truck camper is not installed, the load stabilizing inserts may be angularly adjusted and secured in an open, non-working position, to provide a relatively soft ride during such position.
