If your doing a straight swap @eohat you don't need anything. Use every thing from your 5.3. I did and it ran great on the 5.3 tune also. But if you have a heavy foot it will lean out and pop #7 piston. (Never experienced it but read it)
I recently discover that if you want to use the exhaust off a escalade or Denali the drivers side exhaust manifold is different. Keep that in mind for future mods. I am adding the magnaflow cat back system for the escalade but need to change the front pipes. Couldn't cause of the manifold. Any help you need don't hesitate I will do my best to help

Thank you sir, appreciate that.

You'll have to mod your floor jack with a Snap-on handle and wheels; maybe start a build thread! :D
Done!

Still looks like it says Snap-on, on the right side. Lol

Swapped out new jounce bumpers in the front. This is a Texas RWD truck with 126k miles. Not sure if I expected them to be worse or better. Hopefully it calms down some of the bounciness that I was associating with the 5100's. Easy job and despite 15153958 listed as for 4x4 and another # I found for RWD, these that I pulled off have the same part # and I'm the original owner.
