Just for giggles i also looked it up, The pic for both shocks available don't look like the one you got. Look on the side of the shock and see if that # is on it. One thing about Rancho shocks they put the part # on it. I also looked up my truck and it takes the same one. I just replaced mine last summer so the # must be correct.

 

Quick update picked up a Monroe damper fits like a glove.
