I have king springs and bilstein shocks, they are great, front KDFR- 42HHD Rear KDPR- 58LP, the fronts are the heaviest they make for a patrol, that's what they recommended, but they make the front stick up a little more than the rear which are 300kg progressive, the hd would have been enough, I just put a 15mm spacer in the rear and that levelled it up
