Clamping device for a vehicle suspension

A suspension assembly (10) is provided that includes a first suspension member (12) such as a rear axle housing having first and second opposing sides (14). The housing includes spaced apart comers (16). First (18) and second (20) seats are respectively adjacent to the first and second opposing sides. Each of the seats has inwardly facing surfaces (32) interconnected by an intermediate surface (34) with the inwardly facing surfaces engaging the corners and the intermediate surface spaced from the side. The intermediate surface and inwardly facing surfaces of each seat form a continuous unbroken surface with the inwardly facing surfaces facing one another. A fastener such as a U-bolt (30) or a pair of bolts (26) secure the first and second seat about the first suspension member to secure a second suspension member (22) to the first suspension member.
