Our MM 40SR 400X72.5WX72 tracks are manufactured under strict quality control procedures, and are guaranteed to fit your Caterpillar MM 40SR machine. Our tracks feature a single coated steel cord wrapped continuously around the rubber track belt, ensuring there are no weak points. Further, our Caterpillar MM 40SR are manufactured with twice as many lugs, so that every sprocket tooth grabs a lug instead of every other.
