That is the intended use. The P4X coils are nearly the same as the SV coils. PRG and others recommend 1.5" setting and a spacer. This gives good springrate, good droop. You may even want to set them th 1" setting if you like a softer ride and don't have any armor or bumperWhat do you think about running the Bil 5100's at 2", with the stock coil off a pro 4x? (sorry if this is redundant but it was suggested by a local shop).
