Safety of wheel spacers

So I ordered a set of rugged ridge 1.5" wheel spacers for my 91 yj with a 4" suspension lift and a 1" shackle lift.
I work all week so I didn't want to bother with putting them on, but 3 different tire places refused to put them on die to safety issues.
I don't see what the safety issue is. They appear to be high quality and I'm only running 31" mudders...see pics.

Do any of you have safety concerns with these? I think they look great and my jeep rides nice, just as it did before.

I've never had wheel spacers, but know of guys running them without any issues. They say to check them every now and then to make sure everything is tight and as it should be. I would say the tire shops refuse because of liability issue since people are so lawsuit happy these days. You may just end up having to install them yourself.

Just like said above, as long as you take care of them they are fine. That maintenance does require retorting every 3-5k miles tho and tire shops won't do that for you but if you can do it yourself you're good to go

I figured check them every time I rotate the tires...

Don't forget when you move the wheels out further you change the way the wheel bearings handle the loads. Not that big of a deal for the rear but it can cause some issues with premature wear up front.

Yup. It makes ball joints wear faster too

I would suggest some blue thread locker. There are threads of failed spacers. I would never run them, but my brother does on his little rice burner and has never had them come loose. He is using blue thread locker though.

If you feel that you absolutely need a spacer the definitely run thread locker with them.

But, like was said above, the extra width only leads to problems such as premature bearing failure on all 4 corners, and ball joints wearing out quicker from the extra width.

Its the same as using a wheel with a small backspacing, gets that tire out wider away from the vehicle, looks cool, and actually helps, because the wider stance lowers the center of gravity, but plays hell on the bearings and wearable parts.

I ran 1.5 spacers on my 96 ford diesel in the rear, never had a problem with them

I ran 1.5 inch spacers on my CJ with the Dana 30 and Amc rear with one piece axle kit for three years. Not one problem. Just but quality spacers. Nothing wore out faster.

I have looked at getting some but it sure seems like a bunch of potential problems for 1.5 inches. I chose to not fool with them.

To the guys saying no problems. It all depends on how far you go over stock. If you double the distance from the joints it will more than double the amount of force applied to the joints due to leverage. That is just an example though. Lets say if the hub is 3 inches from the ball joint and you add 1.5" it may add about 60% more stress to the joint. If you are driving down the street no big deal, but if you are replacing these parts every year anyway because you abuse them to failure, instead of every 20-25 trips you may end up replacing the same parts every 10-15. If you drive the thing down the road 90% of the time go for it, but if you are going through 3ft holes out in the woods I would suggest keeping everything as strong as possible.

Just my opinion though. I know no one has any solid numbers on this since I found the edge of the internet looking for an answer on these a couple years ago. I was going to use a spacer on one side of my 8.8 to center the pinion, add the extra width to make it exactly the same as the front, and then weld my SOA perches in place. After researching it I decided I would stick with no spacers since I knew my rear was in for a tough life.
