ok i i have a suspension idea. I usually have 2000k to 2800klbs in the bed of my truck. i used to have a 08 ford f150 crew cab fx2 that did a good job holding the weight. now i have my 10' ram big horn and never put anything in the bed yet. My qwestion is can i cahnge my springs in the rear for springs off of a newer model 3/4ton? will the fit? will the even make a diffrence?
