Description
ATRO EM75-61001-HT high-temperature polyurethane charge-air-cooler (CAC) mount kit — replaces Peterbilt N4751001 and Kenworth N4751001 — used at the CAC isolator position on Kenworth and Peterbilt heavy-duty conventionals. The HT polyurethane compound resists radiator-bay heat soak better than OEM rubber, extending mount life on long-haul and grade-pulling service.
