A vehicle suspension having a trailing arm, an air spring assembly and a spacer. The spacer is removably located between the trailing arm and the air spring assembly. Either or both of the top surface or the bottom surface of the spacer are tapered.

Suspension adaptor

An anti-creep locking mechanism for a trailer suspension system is disclosed. The disclosed locking mechanism includes at least one column that may be swung into a first position in a gap formed between a trailer frame and a suspension component to keep a trailer at a predetermined height. The column is biased into the first position by a spring. An actuator, such as a contracting air bag or an air cylinder with a linkage assembly, is used to overcome the biasing force of the spring and retract the column into a second position, thereby deactivating the anti-creep locking mechanism. The anti-creep mechanism may further include an angle limiter to insure that column is fully retracted once the system is deactivated.
