I just got my rancho 9000's the other day. part# rs9001 for the front and rs9112 for the rear. Question is the front shock tubing (valve body) is a little short compared to my skyjacker shocks. Which would limit travel,right? I called two of the local 4x shops and they all said it was the correct # for a 75 Blazer w/a 4" lift. Is that what everybody is running or is there a better option, besides 9012's with modified mounts. Thanks.
