@jcardona1 is that your front or did you 3 link that rear? that's an interesting way to get around the gas tank for sure. 2fpower and i's goals after discussing options was to try and keep the frame side as stock as possible as future plan's may include different cruiser to get a full cab again for creature comforts. So I played with the stock frame mounts and moving the axle side around to hit a reasonable number. The stock numbers are attached, for 35's and 2.5" lift. bigger lift and tires only make the numbers worst which is what most people deal with and don't have much complaint.
so with my proposed set-up slightly higher anti-squat but roll center and over steer greatly improved the longer upper link helps get there. there's never a perfect set up but believe this one will be right for 2fpower and what he is trying to achieve. with 40's and portal axles the wheel base will be stretched 2" with the mounting points moved back on the axle as far as we can to lengthen the upper link to achieve it.
