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.

A multipurpose splint means for at least temporary repair of a broken leaf element of a spring leaf assembly, the splint means comprising an elongated arcuate spring steel member having a convex surface intermediate ends thereof adapted to be juxtaposed to a fracture in a broken leaf element, spaced bolt positioning means formed in the member at opposite ends of the convex surface for receiving and positioning securement members to attach the splint member to the assembly, the central portion of the convex surface lying exteriorly of a plane tangent to surface portions of the positioning means whereby the convex surface is adapted to realign and retain the broken ends of the broken leaf element. The elongated arcuate splint member is also provided with an end portion extending beyond one of the bolt positioning means, the end portion being upturned at a selected radius to cradle the eye formed at the end of a main spring leaf element in the event fracture occurs adjacent to the eye.
