Wheel spacers for rear

[Johnkn]

While I don't disagree with this, when I checked one of my Mavericks, it only had 7 to 7-1/2 turns of engagement, so with a 1.5mm pitch, only about 75% of stud diameter (14mm).

Interesting,

I went through this 3 weeks ago on my 2026 Maverick XLT FWD with stock XLT wheels. On the rear, with a fabbed .375" (3/8) spacer I only had just less than 6 full turns remaining on the stock lug nuts after torquing to 150, less than what I was willing to accept. ..

On mine, a .250" (1/4") spacer on the rear would be the max and would work, but the juice was not worth the squeeze... I did not measure the fronts.. I wanted to fab the rear spacer and measure before potentially ordering a skinny slip-on spacer from Bora...

I even asked AI and kept getting conflicting info.

I had to laugh when reading that part of your post.
AI CONSISTENTLY will provide inaccurate and/or conflicting information about anything.
It seldom provides a reliable answer so at best, it's a starting point.

Apparently. the human element came through for you...

Unfortunately, the spacer makers don't check their clearances and post the dimensions. Some warn you. KSP on Amazon shows a picture that their spacers are safe and show a graphic. I bought 1" spacers from them and they didn't have the thread engagement I required. I sent an email to them showing that the thread engagement was inadequate - they didn't counter-bore deep enough. I got no response, surprise, surprise. They changed their online graphic, hmmmmm. I sent them back and purchased 1.25 spacers not knowing if they met the safety spec. They did. The thinner spacers can't be counter-bored deep enough to meet the safety depth of the nut seat to avoid splitting or deforming the spacer. The end result is not enough thread depth for the nut. The thicker spacers have adequate counter-bores that allow for adequate nut seat thickness and thread depth. What I am saying in a nutshell is the makers know what is needed but thin spacers require a sacrifice. One or the other. They choose to make the nuts a possible failure point, not their spacer. Then they tell you to use Loctite, which comes with the 1" spacer. Pretty subtle - "We know but don't blame us." I don't/won't put Loctite on stud threads. Others do. Yeah, I know, I'm crazy.

Let me rephrase what i said. I meant to say AI said it will work and i asked again after doing some research and it said it wouldn't work. Same AI app was giving conflicting info. Only reason i was using AI was because i couldnt find answers for my setup and i didnt really want to be that guy who started another thread but here we are. My fault for trying to answer quickly without proof reading.

I understand. AI does that for everything.
Ask a question twice and get two completely different answers.
What I found amusing was that you seemed surprised, because that is very common.

AI models are only as good (or bad) as the data used to derive the answer.
If people from the "Flat Earth Society" provided enough input into the nature of the planet, AI would tell you that the Earth is flat. It's not at all intelligent.
It derives an answer based on the most consistent response, even if the majority opinion is completely wrong.

With anything important, consulting a subject matter expert is light years ahead of an AI response.

Stating that "spacer makers don't check their clearances and post the dimensions" is a false and absolutely ridiculous statement. . It appears that perhaps yours doesn't

You purchased (4) junk JSP wheel spacers from Amazon for <$135 INCLUDING DELIVERY, what exactly did you expect? Stop buying that cheap Chinese $hit sold on Amazon and you'll be just fine.

Point to just one single failure of a U.S. manufactured Bora spacer, just one..

But Bora doesn't list Maverick in their application guide, and Bronco Sport versions would have M12 studs.

Bonoss makes a good spacer, I’ve been running them for a while with no issues. Well made product.

Likely due to very low demand within the Maverick community. Motorsport Tech can absolutely cut a set. They build and finish in-house..

I've use them on (3) Raptors and my TRX, all perfect with zero issues.

I bought some hub centric spacers from Bonoss and they have worked well for me.

25mm front
35mm rear
No modifications to the studs just bolt on and go

Any pics of the stance with the spacers?

What are ya? A Bora employee?

BTW, my spacers cost $111.90, your price quote was off. I still have the invoice.

That is Car Talks opinion of KSP, not mine. I chose them for the shocking blue finish that matched my truck.

I logged in to the Bora site. No mention of counterbore depth.

No mention of counter-bore or cone depth. That is why others have warned to check fitment, with examples, before installing. There wouldn't be a need for this if the dimensions I mentioned before hand.
You said "Point to just one single failure of a U.S. manufactured Bora spacer, just one.."
I rejected a set of Bora spacers in 2022 for a reason not yet mentioned here. The cone seat for the nut had scratches on the spacers. I wiped a thin layer of grease on two of the cone seats and installed and installed the spacers using the other studs. I hand tightened nuts on the two greased cones, then tweaked them with a socket. I removed all nuts and spacers. Upon inspection of the of the two seats, I found no grease on the smaller diameter of the cone with thicker grease at the large diameter of the cone. The nut had a scratch around the bevel at the contact point of the small diameter. I'm pretty sure that the spacer did not have the proper angle on the cone. The scratches on the cone were due to a dull cutter or high-speed machining. It was overlooked by QC if they have such a thing, probably do. I set them back.

Short story for those that want to install safely and correctly. Torque the nuts on the spacer, then remove 2 nuts at random per wheel to see if the nut is scratched at the top or bottom. They shouldn't be if the 2 beveled surfaces mate properly.

China parts are for the most part as good as or better than US made parts. US manufacturers made the foreigners what they are today by outsourcing overseas to save a buck. The Chinese filled the manufacturer's need. Vietnam is now getting in the game - good products cheaper price.

I'll buy parts where I darn well please, thank you.

IMO, this thread covers a lot of the nuances of spacer use.
I was watching TV with my wife in the middle of this. I apologize if I didn't see pertinent info that I should have considered.

Forgot to mention: I forgot to mention that when I use grease to do a fitment check, I thoroughly clean the nuts and threaded surfaces to use the recommended torque values. Lubricated threads used with the recommended torque values result in overtightening which could cause the stud to break or the threads to strip. There are calculations to obtain torque values for lubricated threads, but I won’t be bothered with it. It’s quicker to clean them with carburetor or brake cleaner.
