Composit M66-262-5486-3R Snowmobile Track

SKU: M66-262-5486-3R Pitch:2.86


The M66-262-5486-3R* 62 pounds features a deep 2.62″ lug pattern that is designed to work in a wide range of snow conditions. The flexible center lugs gets you up and on top of the snow and prevents trenching. Great handling and traction in wet or packed snow with excellent performance when side hilling. Durable 2 ply construction gives big bite in back country conditions. The M66 allows beginners to tackle new terrain and opens up endless choices for the experienced mountain rider.

*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!

    I have one under my Yamaha and the thing just works. Traction is now my last concern. I can’t ride with any other track because no other track can compare to the m66.
