Your shock travel will be determined by the articulation of your tie rods in your frame make sure your not bottoming out or raising to high as to hit your frame. Are you making your own shock mounts or are they already on the beam? Coil overs are great once you get them tuned in and unless you've got the money and time to change out springs then I'd go with the fox air shocks buy them bolt them up adjust the pressure and be done. I love mine and unless I was going to run baja or race it I wouldn't spend the time and Money on coils,jmo. Chad
