IMO the 3 inch inch track overloads the motor too much and requires much lower gearing, it helps to get going in bottomless powder but track speed is terrible . The 2.6 track outclimbs the 3 inch with experienced riders in most situations with the available 60ish HP., track speed is everything when understanding the physics at how snow rolls off the paddle tips and compacts creating lift and propulsion. , I suggest a 2.8 center lug with the 2.6 outer lugs and will fit in the current tunnel with the Avid 7 tooth drivers which are a tad smaller than stock. I,m sure minds are thinking at this time what to do next and Yeti is soo refined already its a tough task. there are reasons pro sled riders with turbos prefer the 2.8 track over the 3 inch, simply much higher track speeds creates more lift and in turn allows for a more flickable machine .
The CMX does not get on top of the snow ,the front axle is soo low is subermines under the surface in deep powder , We run the cmx 129 side by side and even the skinny Yeti kit had to break trail for the CMX. . But yes the 3 inch will paddle very well in deep its just such slow of track speed its not a fun for our riding style..Yup - agree with what others are saying about it being dependent on the conditions. I had a 129 CMX 2.5" track on my last aro and in the dry snow of eastern British Columbia it just couldn't hang with the 3" kits everyone else had. It did a darn good job and was more nimble, but on big climbs I had to scab others tracks.
On those hero snow days where the snow was firm though? I loved my track! It was better in those conditions. That was only a couple rides a year though, compared to most of the winter of dry powdery snow.

Thanks i missed that , The CMX track is Super stiff, which hooks up hard in set snow but we all what a stiff track does in powder, The Timbersled 3 inch track does have the optimum track flex for powder .Just to clarify - the CMX track was put on an Aro 120SX with rail extensions.
Funny i feel completely opposite. Cmx just flat out spools up and gets right on top of the snow vs the rest of the fleet. Which is why I actually sold my Aro3 and went to a cmx120… now the aro3 was a tractor in the super deep (not taking anything away from that)but a planted and no playfull feel.. cmx120 blows me away on how well it performs in all conditions and the fun factor is wayyyyy more. I got bored of breaking trail on the aro3 on super deep days. Now im okay with letting my buddies on Aro3s break trail and ill be right on their ass wheeling and smiling ear to ear and sometimes actually steal their thunder and pass em right at the top of a pull.
