I am thinking of putting a 151 on my 2004 summit that has a 144 if i put a 151 with a big wheel kit do i need a longer skid and tunnel? Thanks guys.

No just get rail extensions,I wouldn't waste the 600 $ or more to big wheel it,you already have 7 1/4 " wheels,just port your track that will take all the stiffness out of it.Porting your track helps out alot.Putting a 151 would be the best improvement you could do just make sure you get extrovert drivers also.

Don't get rail extensions just move the skid back 3.5". Way better approach angle for the front of the track. You will just need some drop brackets for it for the rear. You can keep the stock wheels this way as well. I agree though, port the track for sure.

For sure...move the skid back.
