Assault 146 to 151 possible???

[Kushniruk_16]

I have a 2010 assault and wanna extend the track from 146" to 151"....found a used 151 in mint condition and need to know if I can extend trackto a 151

Have to change drivers from 2.86 to 2.52.

Better to find a used 155 and run rail and tunnel extension. Will be cheaper and easier and dont need to change drivers.

155 would be easiest like Sledneck said, but you don't need tunnel extension as far as i know. been running just fine without one. i got 155 rails and bolted up my 146 suspension components, moved rear scissor mount back 5/8" on rails and drilled new mounting holes on rear tunnel mounting brackets. 30 3/4" from front mount hole to rear. ( i believe it is 2 5/8" back from original 146 rear mount)

The only extension I can find that might work is 144 to 154. Will this work on what I need (146-151)?? Besides drivers tgat is...

no need for a tunnel extension, and instead of a rail extension just find 155 rails (lots around, check the swap meet/kijiji/ hell even ebay) and then a 155 track (2.86 pitch)

that is all you need
