Thought a few might be interested in this. It is a general guide that explains the API marks on oil bottles. Just click here

It is pdf format.

API certified oil "the Starburst" is recommended for use in our trucks. This just helps explain it.

  I've got them and I think they work pretty decent, what I noticed right away is it took some of the bounce out of the rear end when going across washboard roads and railroad tracks when not towing. When towing my 5th wheel it seems to make the truck more stable.

  Is your truck not available for you to look? If not, can look at mine later this morning and post back. I suspect they are easily accessible.

  How difficult is it to access these six mounting bolts for torquing? I do not have a lift. I may want to replace and tighten the bolts myself to ensure it is done to proper specs. Since body shop did not do it properly to begin with, I’m not confident they will do it correctly with new bolts. Also, they claimed 74 ft lbs when that is not correct. Also, seems odd that there are only 4 vertical bolts and two horizontal bolts..,, my ford f350 I believe had 6-8 vertical bolts.
