It's weird how many guys speak of "alignment issues". I've been running the same OME 3 inch, with med springs in the rear (due to the amount of gear I tote around) and stock UCA and haven't had a problem. My alignment was perfect. I'm sure the handful of guys that bring up alignment issues are the ones who have a complete understanding of what they're looking for. The guys at EQUIPT are doing a 5th gen build and they have pretty good essay on what they've installed. Considering they do this for a living and have traveled the planet...not just the backyard and used OME for almost all of their vehicles. Below is a quote from expedition overland...

"The Lift

So what to do about it. My goals were to add clearance, add driving performance, add load management, and most of all add dependability to the truck suspension. I decided to go with Ole Man Emu. I have used OME of several of my vehicles, including my 100 Series, with tremendous success. OME builds their componentry to be used on exactly the kind of vehicle I am building here. A vehicle that will carry a significant load on harsh terrain for long periods of time and not breakdown, period. There are a myriad of options out there, mild to wild, and some excellent companies to choose from. But I go with what I know. I have beat the hell out of OME and it has never failed me. I am also trying to not over-modify the suspension or drivetrain on the truck. Toyota is well built on its own, and the more aftermarket components that get involved the further you end up from the engineered intent of the original components and their capabilities. And hence more opportunities for issues far from home. I am going to try to keep it simple clean and tight on this one.

OME has several options for the 5th Gen 4Runner. Most of the options have to do with intended weight capacity. You can go with stock to +400 lbs, +400 to 800 lbs. or +800 & up. I chose to go with the heaviest capacity I could to start with. On the 100 Series, I went through 4 suspension systems before settling on the heavy set up it has."
