This Mack replacement trunnion stand uses a square bolt pattern, works with the MB1 bar, and includes two MX308 collars for a more complete suspension hardware service. Its 1.0-inch frame-hole setup gives the Automann M1213 the heavy-duty mounting detail needed for the intended Mack trunnion position. When the truck requires the square-pattern stand, this replacement provides the mounting base needed to restore the rear suspension support point.
