Composit M770-300-5630-3R Snowmobile Track

SKU: M770-300-5630-3R Pitch:3.00


The M770-300-5630-3R* is 156″ in length with a 3″ pitch @ 62 pounds is a brand new mountain track with 77mm (3.00″) lugs of pure power that won’t leave you behind in soft, deep powder. Well balanced 3″ high lug pattern uses the latest manufacturing technology for exceptional traction in powder snow. The  cupped lugs will flex in the snow for traction yet resist fold-over on the hard pack for improved traction and durability. A lightweight 2 ply track designed to let a rider achieve the full deep power potential of his sled in boondocking conditions.

*Note: The 3R denotes the center ported track which allows bolt on application to all Ski-doo models and all the Polaris models. Some Polaris models need these center ports for their anti-ratchet center driveshaft sprocket.

NOTE: Polaris has a confusing system for their 155″ models as they use 3 different tracks but call them all 155. A 155 can either be the 154″ (which is either 2.86″ pitch or 3.50″ pitch) or the 156″ with 3.00″ pitch.  Pitch is the center to center distance of the drive nubs on the inside of track. These are what your drive sprocket matches to accelerate the snowmobile so you must have this dimension correct to prevent track skipping. Easy to measure with a tape measure. Be sure you order the correct pitch for your model, DO NOT trust a manual or application chart, best to measure your sled!

    Bought this track last year and pretty happy with the purchase, it serves me well. Definitely would buy it again

    I bought this track and in the process of shipping ups had some problems getting it to me. I contacted Composite tracks and they were extremely helpful in me getting my track. I dealt with Dale, so thanks for your help! I have one ride on the track so far. I put it on my Pro Rmk 800 that’s running 12 lbs of boost, and it seems so far to be a really good track. It don’t trench like my Camoplast track did, it gets out of the powder and goes! Would definitely buy again!
