Composit Snowmobile Track

NEWS: Ski-doo joins the 147″ revolution for 2027!
This is our 2nd year with this 147″ x 3″ lug track and now Ski-doo is going to offer it in 2027 on select models. Good for them but when their 1 ply track needs replacement, REMEMBER that we have a durable, 2 ply model that has been tested and thrashed longer than anyone.
Polaris is expected to follow suit but our 147″ fits right onto their 146″ tracks (2.5″ lugs) with just a driver change to allow for the 3.5″ pitch of a 3″ lug track. Popular with many Polaris riders, join the revolution.

The M770-300-4735-3R-6* (147x15x3.00, pitch 3.50, 55 pounds) is a NEW mountain track with 77mm (3.00″) lugs of pure power that won’t leave you behind in soft, deep powder. This track was developed for riders who ride 146″ tracks but want a taller lug. All 146″ tracks use 2.86″ pitch so be aware that some changes will have to be made.
146″ sleds need to have 3.5″ drive sprockets installed to match the track. Polaris riders have enough room in rear axle adjustment to allow track tightening with stock setup. Ski-doo riders may run out of tension adjustment so the easiest is install larger 9″ wheels. When doing this watch for interference on rear scissor arm which may need a small amount ground off bracket to allow clearance when fully compressed.

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 146″ sled in boondocking conditions.

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 models and all the Polaris models. Some Polaris models need these center ports for their anti-ratchet center driveshaft sprocket. 3R-6 tracks have 6 rows of inner drive lugs and will fit Polaris or Ski-doo.

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!
