I put a 2" spacer boost on my 04 Overland GC, then went to an Ironrock 3" lift with coils, new track bar and Bilstien 5100's, rode well, no vibes, a bit firmer handling than stock but that's an improvement.
I fit 265/70R17 tires with a bit of mudflap trimming and minor rubbing at stuff and wheeling. I used the stock control arms and as a result was about 1.5 degrees short on caster. It wandered a bit but not bad.
You can get balljoint eccentrics that will get your caster back, or adjustable lower arms. I considered oblonging the LCA bolt holes on the on the axle tabs a bit and welding a washer on the outside to get that bit of caster back on a budget.
Also note that the Overland 17" wheels are a bit wider than the standard 16's and have a bit more backspacing, meaning the rear shocks will rub due to the larger body on them. I used 1/4" wheel spacers to provide a bit of relief. I also had a bit of rear shock clunk in cold weather that I was never able to resolve with the adapter hardware they supplied, M10 IIRC.
Also at 3", my ebrake lines were serviceable, but getting maxed.
