Finally got around to installing my new Victory 4x4 roof rack this last weekend. Overall, very happy with it. The install is relatively simple and the fit/finish is fantastic.

Unless I've hit my head recently (which i may have), the prinsu has the spacers and uses longer bolts and puts more moment on the nutserts.Mounting looks identical to the Prinsu, L shaped bracket that picks up the stock rack holes.
Ah, getting scientific. Eh, I guess. For price paid, Prinsu has been fantastic for me, moment hasn't ripped it off the roof yet.
How long did it take to get once you ordered? I ordered a front bumper Jan 1, supposed to be done last week, now they are saying another 2 weeks or more. 3 months for a bumper is getting ridiculous.Finally got around to installing my new Victory 4x4 roof rack this last weekend.

A lot of these smaller shops have large lead times due to the nature of their product. Last I checked with Mike at BIOR (mid-December), he was scheduling 4mon out for new orders. While I agree that I’d manage inventory and production a little better if it was my full-time job, 3+ month lead times are not uncommon. Building a bumper is easy(ish). Developing the methods, techniques, and jigs to build it repeatedly with very little deviation is much more time consuming. Fortunately, we don’t drive Jeep’s where you can walk out of 4WheelParts with a bumper same-dayHow long did it take to get once you ordered?

Total height of applied load is all that matters, if the resultant height of the applied load is the same, the nutserts won't see an increased moment, would they? Spacers should just mean the bolts have to be stronger to transmit that moment without bending/yielding.Unless I've hit my head recently (which i may have), the prinsu has the spacers and uses longer bolts and puts more moment on the nutserts.
This one mounts flat on the holes, less moment.
What? No… do a free body and report back.Total height of applied load is all that matters, if the resultant height of the applied load is the same, the nutserts won't see an increased moment, would they?

You're saying the height of the bracket above the nutsert matters, it doesn't. The total height of the applied load above the nutsert is all that matters to the nutsert. It doesn't care if it's bracket then a bunch of material or a bunch of material (spacers) then a bracket. FxD (or PL/4 really but doesn't matter here), D is all that matters given F is constant. And I'm saying, if D is the same between two racks, it doesn't matter if that D is bracket, spacers, 80/20 bars, whatever, the moment is the same.
If it was all in line, yes. But it’s not.
We also aren’t in statics… deflection and resultant loading matters.
One of us needs to draw some pictures…Line of action is roughly the same through all of these designs, close enough. What changes, is the loads and moments on the bolts, brackets, spacers, etc between all these designs.
....I have no idea what you mean by "deflection matters" in this context, you are talking about the moment calculated at the bolt hole. Deflection of any other member, doesn't change that value, does it?
