A suspension assembly and method of use is provided. The suspension is for an axle on a trailer or other vehicle. The suspension assembly has a cross support member connected with or integrally formed with a hanger bracket at the first end of the cross support member. A trailing beam is connected to the hanger bracket. The trailing beam and a mount are coupled with a load air bag and a lift air bag, with the bags located on each respective side of a pivot axis for the trailing beam. This establishes a teeter-totter configuration of the suspension assembly allowing independent wheel travel side-to-side of the suspension assembly.

A double-shear control arm mount is described that includes a base configured to affix to a vehicle portion, and arms extending from the base defining mounting regions positioned between the arms and the vehicle portion. The mounting regions can be below the arms in some implementations. The arms can include first and second arms positioned on opposing sides of the base. The first arm includes a first arm member and a first arm mounting surface angled relative to the first arm member, and the second arm includes a second arm member and a second arm mounting surface angled relative to the second arm member. The mounting regions include a first mounting region positioned between a first side of the vehicle portion and the first arm mounting surface, and a second mounting region positioned between a second side of the vehicle portion and the second arm mounting surface.
