Track swap 121 to 136

[trailrider]

I am going to extend the wifes track from 121 to136, who makes the best rail extentions or am I better off to get 136 rails?? Does anyone have a set for a SC4 suspention?? This is on a 2008 MXZX 550 fan any help would be appriciated. Trailrider

Going that long I would definately go with the rails!! Might be easier to find a old 136 skid from a summit or similar sled and swap it. That's a fair bit of track for a fan if I read correct you will need to reclutch the sled and possibly lower the gearing. U will lose top end speed but being its for your wife pretty sure it's to help it stay on top of the snow. What size track lug are u plannin on using as that will effect a lot?

I was thinking of going with either a11/4 or a 11/2 paddle. Yes I was planning to gear it down a bit. Just trying to give it a bit more traction when we get into deeper snow so I dont have to pull her out quite so often LOL. I wanted to get her a bigger machine but she realy likes this one .
