Specifications
The M17437UB Motor Mount Rear Poly IHC, available through Wofford Truck Parts, is designed to meet the demands of heavy-duty IHC/International trucks by replacing the original rear engine mount with a premium polyurethane solution. Over time, rubber mounts wear out, allowing excess engine movement, increased vibration, and accelerated wear on adjacent components. This part cross-references to OEM numbers 1664728C1 and 1664728C2 and replaces conventional mount part M17437.
Manufactured with fleet-rated poly material, the M17437UB significantly improves engine stability, cuts down noise, and extends service intervals. With proper fitment in the rear engine-mount position, installation helps maintain alignment, reduce chassis stress and support truck operations under full load. Whether you’re servicing an IHC 4900 series or an older International tractor, this mount is an effective upgrade.
