M1213

TRUNNION STAND REPLAVEMENT (MACK)

This is a heavy-duty replacement trunnion stand designed for Mack trucks equipped with a Camelback rear suspension. It supports the trunnion bar, which allows the walking beam to pivot smoothly. When the factory stand becomes cracked or worn, this aftermarket part offers a durable, easy-to-install solution that bolts on from underneath the frame rails without removing other components, minimizing downtime. The kit includes the stand, collars, and hardware, and is built from heat-treated alloy steel for extended service life.
