I am looking to extend my M-10 suspension from 121" to a 136". Does anybody have any pros or cons on doing this. I have heard M-10's don't hold up well with the after market extensions. I still ride vintage sleds, it is on a 97 Polaris XC 700.
I haven't had a problem with mine and its been extended for 3 yrs now, I did break a drive shaft but it wasn't due to the extension, order the long track coupler blocks from FAST if you do it, you'll like the ride
