Abstract
A suspension beam with a captured axle is described, including a top and bottom plate, a pivot mount, and a spring mount, and side plates. Optional embodiments include an axle sleeve, multiple top and bottom plates, a u-shaped member in place of the side plates. The pivot mount includes a bush housing and a bush housing clamp. The side walls may be recessed, flush or outboard with respect to the top and bottom plates. The top and bottom plates are directly attached to the axle or axle sleeve, and to the pivot mount.
