ABSTRACT:
A load assistance device for increasing a vehicle's ability to carry loads by stabilizing a multi-leaf vehicle spring connected to the axle of the vehicle including a unitary length of metallic spring material adapted to be connected directly to the multiple-leaf type vehicle spring at opposite ends thereof forwardly and rearwardly of the axle connection. The length of spring material has a raised area at generally the midpoint thereof spaced from the uppermost leaf of the vehicle spring when mounted thereto and a plurality of springs of varying lengths mounted between the unitary length of spring material and the vehicle spring configured similarly thereto. The plurality of springs also have a raised area conforming to the raised area of the length of spring material forming space between the uppermost leaf of the vehicle spring and the lowermost one of the plurality of springs when coupled to the vehicle spring. A bracket is mounted on top of the unitary length of spring material at generally the center thereof spanning the raised area thereof and generally conforming to the configuration of the unitary length of spring material at its raised area. U-bolts having an offset upper portion are used to secure the load assistance device to the vehicle's preexisting multi-leaf spring.
