Definitely appreciate it @REALM. I agree with your thoughts on the impacts of rotating the offending tires to the rear which might only mask a continuing problem. I am also going down the rabbit hole of evaluating and potentially resurfacing the mating surface of my Ridgeline wheels since I got them powder coated and checking the surfaces of my rotors since I’m mental.

I just confirmed all 3 shims are in both sides, but check this out, I went and did some driving over a bumpy road, and took measurements again, and the gap has already closed to 34.5 Front, 34.2 rear, after one drive, so... perhaps these will settle more than I thought. I’ve updated the post with that info below.

So, finally, the 1.5 traxda rear lift (three .25 spacers) did not raise the rear 1.5 inches?
I’m a bit confused. If I was to order traxda’s kit, and would like a 1.5 overall lift (front and back), which kit should I order?

In the other hand, do you think a 2” lift would be better, based on your experience?

thanks

Talking to JonDZ, and watching Traxda videos, it looks like the Ridgeline has a nearly 1:2 ratio with the rear suspension design, meaning if you put a 1" spacer in the rear, you'll get about 2" of lift. Traxda has a really good video explaining how and why that works. For the Passport however, the rear suspension is a little different, and seems to be closer to a 1:1 ratio, meaning a 1" spacer is going to give you 1" of lift. People who took the early leap like me are learning this, and JonDZ confirmed he found the same.

The Front 1.5" lift from Traxda indeed raises it 1.5", if not a hair more, and what I did.
The rear 1.5" lift however, are .75" worth of spacers, and is only going to lift it about .75", which is also what I did.
Looking at their site, the 2" rear only kit, I would venture to guess is actually a 1" spacer, and you're only going to get about 1" of lift out of it.
If I were doing it again (and may eventually do this), I would call Truxx and ask what the actual physical spacer size is of their rear lift kits, because whatever that physical size is, is about what you're going to get.

Realm, interesting! In looking up rear chassis parts the Ridgeline and Passport do have different part numbers for the upper and lower arms but!,,,, the subframe where they attach are identical part numbers!
That kinda defeats the “different mounting points therefore different ratio” thought.
I did see a Honda video a while ago where they showed the different (upgraded) parts on the Ridgeline vs Pilot for strength/durability for better off road use.
only way to be totally positive is if someone purchases upper and lower arms for a Ridgeline and Passport and measures the actual distance between mounting holes vs just the look of the part.
Another thing notable is the trac arms between the two vehicles is the same also.
And yes, I watched the Traxda video on the rear ratio difference vs other vehicles. If the Passport/Pilot had a different pivot ratio than the Ridgeline there is no way the subframe would be the same part. You’d need the lower mounting points to be further out.
Thoughts??

Tkanks for the input!

FYI I updated my original post with what I would consider final settled measurements after a few months:
34.25" front | 34" rear

Update I have a 2" rear only kit on order from Traxda, which they said is a physical 1.25" thick, so that's about what lift I expect to get out of it. Ridgeline would get the full 2" I believe.

They also confirmed I could stack one of the .25" plates I have now on top of the 1.25" spacer, as then I would get a total of 1.5" physical spacer.
Right now I sit at 34.25 front, 34 rear unloaded.
I'm leaning toward replacing the 3x.25" spacers I have now with the single 1.25" spacer, which would put me at about 3.25" front, 34.5" rear unloaded.
If I did the .25" spacer + 1.25" spacer, I'm more likely sitting around 34.2" front, 34.75" rear unloaded.

Realm, I’m still at a loss as to the difference between Ridgeline and Passport difference in the rear.
as I posted above, the mounts are the same part number. Therefore the pivot points are exactly the same.
The passport rear track is 66.7”
The Ridgeline rear track is 66.8”
How, pray tell, are passports not getting the exact same lift? Doesn’t seem mathematically possible?

Wanting a mild lift myself but waiting to see the Trailsport edition to see about just swapping suspension parts from that model if it gives at least .5-1” better clearance.

It's a great question that I don't have a reliable answer for, other than my results, and confirmation from JonDZ, who told me what they're finding is the Passport has more of a 1:1.1 ratio, than the Ridgeline 1:2 when it comes to lift results.

My best guess is the Ridgeline has something different in the rear suspension, to compensate for heavier payloads, which would make sense. I wish I knew myself.

I moved to larger tires, and put in their 1.5" lift in front and back (not the current kit of 1.5" front and .5" rear), I did the 1.5" kit in the back as well which is .75" of spacers), and still only got .75" of lift.

Will post results when I get the new lift in, as that will also be telling to see what happens this round.
