I'm starting to parts collect for my wife's '98 4.7L XJ. For the street we want low lift and decent size tires, so we're thinking 285 or 295/75R16's and less than 4" of lift. I have experience with Rusty's 4.5" coils on our last '96 XJ but they are a little tall for this project since we'll be raising the fender flares and cutting the wheel wells up a bit, whereas before with 33x10.50's we didn't cut anything.
I have an 85lb winch bumper (minus winch) and 12,000lb winch that needs to be supported, along with an Optima Red Top and some minor frame plating up front. Granted, we're also removing the front bumper which weighs what...30-40lbs with all bracketry included?
The key question here is, how soft will the springs get when placed directly atop the axle tube, compared to being in the factory position in front of the axle tube? Ideally I'd like to find a 3.5" coil with a 175-190lb spring rate. Does such a beast exist? I'm stretching the front just enough to place the coil directly atop the tube. That should be what...2.5" or so?
Side note: the rear is getting stretched with Blazer ZR2 leafs. That will relocate the rear D44 back about 1.5" and net 2.5" longer leafs, plus a 4" lift with greater load capacity. I'll relocate the shackle if need be to compensate for the longer leaf.
