Just did 2 inch shackles and 2 inch crank.
I had mine cranked two inches and within two weeks I had a brand new broken CV shaft. Eighty bucks later i have them at 1.5", can't really tell a difference between 1.5" and 2", but so far in a month I aint broke another one. Better safe than sorry (and broke)
The reason I can't tell on mine is I accidentaly hacked more of my fender off than I was going for...sawzall got away, happens with cheap blades
. But yeah I could def tell before I hacked it, that extra 1/2" helped.
Well. 2 months later and around 6K miles and zero problems. I've drove the hell out of it to. Had it up in the air to check everything out the other night and everything is still nice and tight like it was before. Been keeping everything greased well. I ended up going with some cheap walmart 31s, but so far, I've been pretty impressed with them. They make zero noise on the highway and cleanout pretty damn good. Had it stuck pretty good twice. Once, I had to be pulled out the other time it somehow managed to crawl out the next morning.



This is the one it somehow managed to crawl out of....

The aftermath.
