Bora Spacer Failed (2 Viewers)

[ChilaMan]

Hello folks. Looking for guidance here. I couldn't find anything remotely close to this issue. So it's well known that Bora spacers are at "top of the food chain" for 100/LX470. My 2000 LX470 drivers side spacer studs SNAPPED right off as I was pulling into my driveway, thank GOD!!!. Talked to Bora, they want me to send them in because they are still under warranty. I'm not sure if I want to put them back on. BTW, they where installed/torqued to Bora specs. What is everyone's thoughts???

They certainly look over-torqued. What ftlb did you go to on them?

Makes me think out of calibration torque wrench.

Most steel wheels aren’t compatible with spacers if the spacer is shorter than the OE lug studs. Do your steel wheels have “pockets” between the lug nut holes on the mounting surface?

This.

My rock warrior wheels also could not use the factory lug nuts.

Since 4 lugs snapped I’m going with install or compatibility issue.

+1 for this...

You are extremely lucky... and thanks a lot for reporting this here for others to learn. A discussion from a tundra forum - Steel and alloy lug nuts - https://www.tundras.com/threads/steel-and-alloy-lug-nuts.88585/#post-2228169

100 lb-ft as per recommended

I can't speak for BORA as I'm about to install SpiderTrax but I was under the impression that steel and allow wheels had different torque specs (speaking of wheel to spacer, not spacer to truck) and that steel was 85-90lb/ft and alloys were over 100lb/ft. And 75-85ft/lbs for spacer to truck.

Sidenote: what's the date code on those BFG's? I haven't seen that shoulder design for a long time.

Edit: With your example, it definitely looks like the original stud extended beyond the spacer's mounting surface...

It looks to me that the wheel has never touched the front of the spacer. I could be wrong but it seems that the wheel was riding on the (Toyota) studs and not the face of the spacer. The original studs are also unlickely to be exactly equal length so your Bora studs would be working against that too. You are definitely lucky that you got home safe.

Another thought to confirm. Look at the back of your wheel and I'll bet you'll see 5 worn spots where the studs were hitting.

You can see that the studs are indeed too long. That spacer is not compatible with the 100, IMO. If BORA sold you those for the 100, I would triple check that it's the correct depth. It appears to be too short and that would put a lot of stress on the lugs and cause premature failure, I'm sure.

Eeek.

Are you able to take a side profile picture to see how far original studs stick out?

Can you measure how far studs stick out?

 

[GTV]

Are those 1” spacers? The most common size for spacers is 1.25” so the spacer is thicker than the original studs are long. Narrower spacers aren’t usually a problem since most (all?) OEM alloy LC wheels have pockets machined between the lugs to allow the extra stud length to pass through. Your steel Tundra wheels are not designed like that though.

Exactly what I was thinking. They look like 1 inch so they aren't intended for 100 Series/LX470.

I believe they are intended for the 100 just not for a steel wheel.

Well, I was looking for 1" because I thought 1.25" was too much and couldn't find any. While watching a Slee video on install I seem to remember the Tech saying 1.25" was the smallest available due to wheel stud length. (Although I do understand that alloy wheels sometimes have voids that would allow for stud clearance. And that I'm also conflating Bora and SpiderTrax data)

I think it's entirely possible that SpiderTrax doesn't offer a 1" spacer for 100 Series to avoid this exact scenario.

 

[Trapper50cal]

that info is in one of these, the first I think.

 

[Trunk Monkey]

It's 1 min in to the first vid. Be interesting to see the back side of the OP's wheels, if there's 5 divots where the factory studs are.

Could probably go 20mm or 3/4” with most OE alloy wheels. BORA is made by Motorsport Tech and they can custom make them for you… if that is something somebody wanted.
