I think pizzaman is right. Again when I go to look up these part numbers I'm getting conflicting things. On rockauto.com it lists a RS7792 for a 4WD truck and doesn't even show a RS7000 shock for a 2WD. However over on 4wheelparts.com it lists a RS7767 shock for a 2WD, BUT it also says that the RS7792 is compatible with 2WD. So I have no idea which one should be the right one! I'm working with the Rancho rep to figure this out and hopefully rectify the problem.

 

Got your e-mail and responded. I have a few questions for you.
Hit me back and we will get this figured out.

 

This issue was resolved. The Rancho 7000MT shocks are not available for 2wd trucks. Rancho has responded and remedied the problem.
