tunnel and 136 question

[SledheadDrew]

Well im looking at a 136 m-10 my 94 already has the m-10 tunnel brackets mounted on it however its a standard sled with a 121 track. Is it possible to mount a 136 m-10 on a 121 sled without extending the tunnel? I hear that the longer track makes for a nicer ride aswell as an m-10 upgrade can anyone help?

No. When suspension flattens out the back of your track will hit your rear cooler and snow flap. 121 to 136 should make your foot print 8" longer. The M-10 is awesome ride and i have heard that the newer sleds with 136" ride better than the 121" in the bumps.
