I used the Sidekick setup on mine for years. Worked okay with 35's, as long as the ARB was not engaged. With the front diff locked, no way could I turn on slickrock. My wife's sammy had the celica box and pump, and in my opinion was not as good as the sidekick stuff. I'm now using an FJ-60 box in mine (37's, D44, Detroit), and a Toyota IFS box in hers (35's, Lock-Right, toy axles). We are both using the PSC pump from Spidertrax and Rock-Logic hydro assist. They both work great, but a big reservoir and cooler are mandatory.
