Our MST 300 350X100X53 tracks are manufactured under strict quality control procedures, and are guaranteed to fit your Morooka MST 300 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 MST 300 are manufactured with twice as many lugs, so that every sprocket tooth grabs a lug instead of every other.
