ABSTRACT:
A traction device for a motor vehicle, includes a rear support assembly bolted adjacent to a leaf spring opposite to a rear axle, a front support assembly which is pivotally attached to a front end of the leaf spring, and a rigid link which extends between and is attached to both the front and rear support assemblies at locations spaced from the leaf spring. The front support assembly includes a pair of generally triangular plates wherein a bolt at each apex connecting the plates performs a defined function. Specifically, a first upper bolt extends through a front spring eye of the leaf spring to provide a pivot axis for the front support assembly. A second upper bolt is positioned to extend across an upper surface of the leaf spring at a location spaced rearwardly from the front spring eye, to limit pivotal movement of the front support assembly relative to the leaf spring. A third bolt extends between the plates at a lower end thereof to secure a front end of the rigid link. This rigid link includes an elongated link tube or bar having eye connectors threaded into the front and rear ends thereof. The eye connectors have opposite threads relative to one another such that rotation of the elongated bar about its longitudinal axis changes the overall length of the rigid link.
