Abstract
A frame including a pair of rear frame rails having a front bracket and a rear bracket. A leaf spring is connected at a front end to each front bracket and at a rear end to each rear bracket, with the leaf spring having a longitudinal direction between the front bracket and the rear bracket. The longitudinal direction of the leaf spring is non-parallel to the rear frame rails. Each rear frame rail includes a notch extending between the outside face of the rear frame rails and the bottom face of the rear frame rails. The notch allows the leaf spring to rise to a level above the bottom face of the rear frame rails during jounce. The frame also includes an axle perpendicular to the leaf spring. A pair of shock absorbers are connected to the axle and an outside face of the rear frame rails.
