Posting this b/c I never could find an answer to this q. Hopefully this helps someone.
Started from stock suspension front and back. No rear TSB. Wanted to level my truck. Lots of posts say 5100s at 1.75 with rear TSB make you level. Never could find out if that would make me nose high (which i absolutely did not want) without rear TSB.
Pulled the trigger. Looks level. Not nose high. Couldn't find my tape measure, but a level on the bed says I'm maybe 1/2 degree tail high. Just what I wanted.
Just putting this out there in case someone is looking for that info.
