Composit Snowmobile Track
M66-262-6386-3R
163x15x2.62, pitch 2.86

The M66-262-6386-3R* (163x15x2.62, pitch 2.86, 65 pounds) features a deep 2.62″ lug pattern with center porting that is designed to work in a wide range of snow conditions. The “Pop-Up” 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 M66-3R* allows beginners to tackle new terrain and opens up endless choices for the experienced mountain rider.

NOTE: If you are unsure of the pitch of your current track, see the “TIPS” section that explains pitch and how to measure your track.

*Note: The 3R denotes the center ported track which allows bolt on application to all Ski-doo and Polaris models. Some Polaris modes use an anti-ratchet center driveshaft sprocket so the center ports allow bolt on application.

NOTE: Polaris has a confusing system for their 163″ models as they use 2 different tracks but call them both 163. A 163 can either be the 162″ with 3.00″ pitch or the 163″ with 2.86″ 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!
