which extension is best for extending a 121 to a 136 i bought most of the stuff as a kit on ebay and now i just need the extensions i think the 2 in paddle might be a little much for midwest riding but i can always cut it down

I will go with the track USA and try to get maybe an 1.5 or 1.25 lug track. I think you will be happier with it...Did you get tunnel ext too....
no tunnel extension got a brake going to bend one up

Tracks usa are the best!
tracksusa use to be the best but not many people know of the new one's from rich motorsports.They allow full slides.

might try a 1.5 crossover if you are not studding. If studding, stay with 1.25 or less regardless of length. I have a 151 1.5 crossover on my viper & it worked OK for trail riding & is Kind of OK in deep snow. (not a 2", so won't work like 2" in deep snow) I had no hifax issues when 2" guys were burning up on trails.
