Our MST2500 850X150X66 tracks are manufactured under strict quality control procedures, and are guaranteed to fit your Morooka MST2500 machine. Our tracks feature a single coated steel cord wrapped continuously around the rubber track belt, ensuring there are no weak points. Further, our Morooka MST2500 are manufactured with twice as many lugs, so that every sprocket tooth grabs a lug instead of every other.
