Was originally going to run extended shackles and Colorado springs on my build, but found out that not even engineers can get them certified. Pretty sure they're illegal in all states, which sucks, especially when you look at how solid the aftermarket extended shackles are compared to OE.
I think they're outlawed because they're too easy to make your own sketchy backyard version and you're messing around with the suspension geometry? I know a bunch of guys run them with Colorado leafs though, meant to give way more flex and a much less harsh ride. I'd love to do it but I'd rather be insured.
