I had the '19-'20 test caliper making its rounds on here shipped to me, and I shipped it onwards to someone else. I think it was about $25 or so.

I guess I'm curious about if this '19-'20 upgrade is a significant improvement over the NNBS '07+ upgrade? I mean, my truck doesn't have the Hydroboost, and from reading through one thread about how to add it, it looks a little intimidating to me, so I'm not sure I want to go to that extreme.

Since the '19-'20 calipers are not (very) available new, and I am reluctant to add the Hydroboost, would I really be missing out if I just did the '07+ NNBS upgrade, since it's cheap, available and still (by most accounts) a good bit more effective than my current non-Hydro NBS brakes?
I have the nnbs calipers rotors and baer brake pads on mine it exceeded my expectations on stopping.I cannot comment on the difference on this setup and the new 19-20 upgrade.I did not want to go thru the my rims dont fit and run spacers.This brake system works just fine for me and thats towing also.Highly reccommend you upgrade your lines to stainless goodridge all the way.

I would not bother with hydroboost. I don't see the benefit when a vacuum booster works just fine.

Can't hardly find this stuff in OEM - RockAuto only has rear calipers, all the GM Parts stores I've found say they're discontinued or unavailable - Amazon has the pass front, but it's doubled in price, opportunism from someone who bought a bunch, is my guess.

Supply chain issues? Can't get brakes for one of the most popular models of truck out there. Craziness.
Best bet is the auto wreckers. That’s where I got all of my setup.

Same.. I have vacuum assist, no hydroboost. I used the Powerstop Z36 front and rear, the NNBS upgrade for fronts, and the goodridge stainless lines. Braking is significantly improved and I am quite happy with it. She stops on a dime when compared with performance prior to the upgrades. Have had to make several quick / not quite emergency stops, and have always stopped well before I expected.
