Good Times, thanks for the informative insight you gave as well as everyone else's views/opinions.
It looks like I'm going to forgo the spacer lift, save the money from possibly not being satisfied with the spacers, and just go for the OME's. OME's really aren't a bad deal for around $700 and I feel like you can't go wrong with OME/ARB products. The X-Reas feature isn't something that I was looking to totally retain, just keep if possible. I can feel it work when driving into corners, but in the long run I don't think I'm going to let it be the deciding factor on how the 4R is going to get lifted. The key here for me is to keep the same ride comfort of the truck, not a jouncey or harsh ride. Plus down the road I'm considering on adding the Shrockworks front winch bumper so an OME setup would already have me where I need to be with a medium/heavy spring setup vs. a heavy bumper on stock spaced out coils.
Thanks for the info on the diff drop kit. I was looking at it from ToyTech's website and wasn't sure if it was a necessary thing or not. Coming from a Heep, a 3-4" lift was hit or miss with getting drive-vibes unless the T-case was spaced down a bit. I just though it would also be easier on the drivetrain, but if you say they're worthless, I'll go with your advice.
Also thanks for the info on the control arms. Don't really hear about a whole lot of people saying they get it or not unless they have an extreme off-roader. I'm not sure about what I'm going to use for a tire size just yet. I like ProMed's setup with his 275/65-18 tire size. 285 might even be a possibility. But if I don't need them, then that's about another $600 back in my pocket. Spidertrax wheel spacers will probably be my alternative (not a big fan of spacers, but I've yet to hear anyone say something bad about them).
