ATRO MM75-62372 Rear Engine Mount for Peterbilt 379, 387, 320

Product Overview

Upgrade your truck’s suspension with the ATRO MM75-62372 High-Temperature Polyurethane Rear Engine Mount. Engineered and manufactured in the United States, this heavy-duty mount is designed to withstand the extreme heat and rigorous vibration of demanding commercial vehicle applications.

Unlike standard rubber mounts that degrade, crack, and soften over time when exposed to underhood fluids and high temperatures, ATRO’s premium polyurethane blend offers unmatched durability, a longer service life, and chemical resistance.

Why choose ATRO Polyurethane? It delivers superior tensile strength and chemical resistance compared to traditional rubber, keeping your engine properly aligned and reducing cab vibration for the long haul.
