Everything included you might need, with the possible exception of a little red rubber grease for the seals (easily available on Amazon). The only thing that really held me up with the fitment was the fact that I was working on a 2004 Allroad, and neither of the two struts had been changed before, so some of the bolts were seized. I'm a DIY enthusiast, but found the actual process to change these fairly simple. They've now been on several weeks, and no drop in suspension, so very much a cheaper alternative to others available elsewhere. Go on - get stuck in!
