I did the oft kit, which has the tip up at the rear. I went from 121 to 136 and its a whole new sled.

 

[Confused?]

Hows it handle on tight twisty trails compared to the 121"?

I am going from a 121 ad boivin expert x susp. to the expert x 144 I am not using the stock susp. so I am looking for info on just the tunnel extention.

Hartman make the best extention for your tunnel.
It is what OFT uses for there kits. Very good quality, if it wasn't, OFT wouldn't use it in there kits. I have the 136" ext on my sled, top notch.

I would recommend the OFT kit, top notch products and customer service. You won't be disappointed.

I just used the XTX yamaha parts and a skins rear bumper.

OFT and Hartmann are good extensions, I've seen them in person. But i think the tracks usa extension looks nicer...it basically looks factory.

I installed Track USA 144" extension last winter and loves it. For the price it is really good. Installed better boards at the same time and it all fits good (for being american design )
