The X3 track reviews compared to Polaris tracks on here always baffle me. I’ve ridden the x3 on many sleds, including back to back on similars Axys on a good snow day on tough climbs...and have never felt it do anything the OEM 2.6 wouldn’t. Always been underwhelmed by that track, but everyone on here seems to love it....different snow I guess.
The OEM 3” is a weird one...I find it much like an x3. A little too stiff. Both work good in denser snow, but dig in dryer stuff. Also when you get slowed down with either 3” and they start digging...they just kinda keep digging. The 2.6” spins more, but it doesn’t dig to China as much at slower ground speeds.
