Vehicle suspension assemblies including air spring assemblies and components of the vehicle suspension assemblies are described. A vehicle suspension assembly that is attachable to a pair of vehicle frame rails includes a pair of support beams and a cross member, such as a cross tube, extending between and connected to the pair of support beams. Each support beam includes a locator-tab and each air spring assembly includes a locator-tab-slot for receiving a locator-tab of a support beam. The cross tube is fastened to the air spring assembly via a retention strap that wraps around portions of the cross tube. The locator-tabs and locator-tab-slots may be operable, alone or in combination with the retention strap, as a lateral restraint. In this regard, the lateral restraint may restrain the air spring from moving in a lateral direction between two frame rails to which the vehicle suspension assembly attaches.
