1/50th Lift Axle pair for Trucks

This is a pair of lift axle assemblies for semi truck tractors etc. The concept is pretty simple, in that the axle simply rests in the 'hook' position when up, and free floats when down. These should fit most 1/50th truck frames, but since there are differences depending on manufacturer, may require some modification.  Should there be a question or concern contact me via the designer link or direct via email to modelmechanic@gmail.com
