Installed it earlier this year, did the rubicon with a stock 231 and my stickshift a few years back it was quite frankly a pain (4.10s and 33s). Stalling all the time and way too fast for the technical stuff. Just got back from the rubicon with the same jeep and the teralow was a dream. Worked well and had so much more slow speed control. The clutch thanked me.
So far so good, one of the best mods to date
