Abstract: A trailer suspension of the type including a leaf spring pivotally connected at its opposite ends to the trailer frame and supported at its midpoint by the wheel axle has a special saddle assembly for securing the axle to the spring. The assembly includes the usual pair of U-bolts engaged around the spring and axle with the threaded ends of the U-bolts extending through openings in a saddle block so that nuts can be turned down onto those ends to clamp the spring, axle and saddle block together. Also a torque arm connects the saddle block to the frame forward of the axle. The saddle assembly differs from conventional ones, however, in that its saddle block includes an extension which extends an appreciable distance along the axle and the extension is provided with openings fore and aft of the axle for receiving a third U-bolt engaged around the axle.
