I just installed a Mopar 2 inch lift kit on my 2019 Laramie Quad cab 4 x4.The rear height is about 3/4 of an inch lower then the front with the bed empty. I usually have a loaded bed and would like to lift the rear another inch to compensate for a loaded bed butt sag..Any thoughts I have a 1 inch spacer for the rear that mounts under the rear coil spring that I could use, the spacer with the Mopar kit mounted on top of the rear spring.Or are there stiffer rear springs or off road package springs that may help.Any input would be appreciated.
