Just to give an update to my comments.
Here in Denver, Slee Off-road has and extremely good rep. It has been in to the shop 5-6 months ago and got back today. I started out looking for info on lifts. I laid out my driving and how I plan to use my TRDORP off road.
In a nut shell 90% on road. Mostly short trips to/from the kids school. Longer trips are up skiing (Winter Park, Steamboat, Crested Butte) and similar areas in the summer for camping and easy/moderate off-roading.
He said there were two kits to start with. One was the OME with UCA and the second was 6112/5160 with UCA. He said if I wasn't going bumper, winch and spare tire carrier, I shouldn't look at the OME kit. He said the ride quality of the OME in an empty 4Runner was to harsh. He outlined how the OME kit really shines when the rig is full loaded but that isn't how I'll have my TRDORP setup daily.
The 6112/5160 combo with UCA and OME rear springs was the setup they commended. The ride quality is not harsh in any way. The quality of the shocks are top notch and there are no fitment issues. They have done several 6112/5160 installs and believe is the best option unless you step up to fully adjustable Fox, King or Icon. They didn't suggest using the Boss options. They said if your looking at them its better to spend the extra money at least Icon or Fox/King. Another interesting point is they outline how here in CO the environment (dust, mag-chloride, sand/gravel on the winter roads and so on) is really hard on these types of shocks. The higher end parts don't always hold up to the abuse of CO roads and elements. They have seen much fewer issues with 6112/5160 then other more costly options.
For me ... I'm going with 6112/5160, UCA and OME rear springs. I'm pretty sure Slee will be doing the install. They include a alignment with the install. They also keep measurement and feed back for every install they do. They know inside and out what works for what people are looking for
