a properly set up 4 link will drastically out perform a 3 link rear with track bar. if that was the case that a 3 link rode better then you would see 3 link suspensions all over on the market produced kits.
im sure im not the only one who will think you will wanna maybe change the rear out to a 4 link.
how ever i am interested to see where the truck goes from here. where you at in alpena. im from up there. still have a place in ossineke.
