These heavy-duty motor mounts are another O.E.M product taken to another level by Midgets Diesel. After miles of abuse from towing, racing, and everyday driving, we found the O.E.M. ones just don't hold up. In many cases the engine oil pan will actually contact the cross member beneath it, succumbing to the weight of the heavy Cummins engine. Our Motor Mounts provide a semi-rigid solution for the weak factory motor mounts. Due to the nature of the harder durometer bushings, the energy of the engine is delivered more efficiently to the frame resulting in more vibration than in stock form.
