Got a wild hair and am considering converting a 121 600 IQ to a 136 track. Does any have an idea of what it might cost. Obviously a new track and rail system. What about clutching, would there need to be any major mods to that. Any way thanks for any input.

TracksUSA is the best price on a kit....around $750 depending on your track choice. Or you can piece it together and save some money as stated above....he must have found a used track but good price on it.

I have also done the 121 to 136 extention. I agree with whitexc, Tracks USA has the best kit on the market. I have one on my '06 700 Fusion, world of difference form before.

I bought all of mine used. TracksUSA rail extensions $80 HCS, 136" Ripsaw from a Crossfire $205 ebay, and RMK tunnel extension ebay $30. Depends on how quickly you want to get it done.

^^^It is an excellent kit. Fit and finish is like stock. The extentions make for a solid rail unlike other kits which do not extent the hyflex or slide rail. Easy to install as well, with a few simple hand tools it can easily be put on in an evening. Strenght, I am not afraid of the extentions breaking or coming loose, and I have abused mine last season.

just a few pic i took durring and after 85 slp ext kit 250 track 95 tunnel ext new hi fax 30 didnt for ext just needed to replace 250+85+90=425 or you buy a kit from tracks usa 700+ your choice i chose to save money to more in to my sled
So then the undercarrigae/suspension/hyfax rails are an extension from what I can see, u don't need a whole new undercarriage for the longer track size. Thanks for the info.

Yes you did save money by buying all your stuff one piece at a time, but you bought the SLP rail extentions. The SLP rail extentions work just fine don't get me wrong, but they don't fully extend your hyflax and with that are not as strong a mounting system as the Tracks USA ones. As you can see form the pic I added. Your rails now have a weak spot directly below the mounting point and a hard impact can cause failure after a jump or other impact. You may have saved money now, but in the long run the Tracks usa rails will last longer then the SLP extentions.

I have to agree a bit here...SLP makes some nice stuff but I questioned their extensions. I ended up going with an RMK skid so no extensions were needed. We did a tracksusa kit on my buddies v-max and the fit and finish was great.

As stated, you can save money if you piece it together. Not everyone plays the fleabay game and some just want to buy it and ride it. Good luck with whatever you choose...you will be happy you did it.
