Today i received my rs9000xl series shocks. Let me tell you, they're not as easy as it looks. But luckily not too hard either. All you need is a set of sockets, ratchet, pipe wrench, and a couple of wrenches. Oh and some strength. The rear are definitly the hardest ones because its impossible to get a wrench in between the shaft and frame. The easiest way to do them is to take the bottom bolt out and just bend it back in forth breaking the top one off. NOTE: Only do that last step if you dont plan on reusing or selling them.
The front ones all you do is put the pipe wrench on the metal wrap on the shaft and proceed to take the nut from above off with ratchet and socket, mine were 19mm. took about 30 minutes to do the front and about 1.5 hours to do back because i didnt think of breaking them off until i was tired and pissed off from trying to take them off. so really one of the back ones took about 1 hr. the other 30 minutes top.

 

I just replaced mine and the back shocks are a royal pain
