Best Bilstein 5" Coil Over Kit?

[Koolaid]

Do any of you guys have a preference for a coil over kit for a Bilstein SZ series? I have a KRC on one car that works ok, but seems like the aluminum threads are a little on the soft side - just wondering if anyone else makes a kit that is really nice. This would be for a 5" spring. Thanks.

BSB makes a nice one but they all seem to have the same thing about threads getting knicked up.. Try wrapping threads with a little ducttape to help protect them from rocks..
