Question on 10mm wheel spacers

[SHAGGY101]

I will be going to 285/75 R18 (most likely the MTR kevlar variety unless I am convinced otherwise) in the next few months. I have a body lift and the ability to trim parts of my fenders if need be. I know that anything between a 1" and 1.5" spacer will cause me to rip my fender off at full articulation with the wheel turned. I have been told by others that a 10mm (~.394" nominal) spacer is the way to go.

My question is that I cannot find 10mm Al stock (didn't expect to). So how exact does this spacing need to be for the lug nuts to fully engage the the studs (running tundra steelies) and to also not rip fenders off? I can get 1/2" (.5") or 3/8" (.375"). I also have the ability to get the .5" stuff and then fly cut it down. My options are open. Just want to get some input before I start doing more work then I need to.

There is a great shop in Reno that can make you a custom set of 10mm spacers. I think a set of four ran me just over $200 shipped. Spresso pointed me to them. Bluecruiser and a couple others are running them as well. Maybe one of them can give you the link to their website. I am on my phone and wont be home for a couple days.

Also, take you time when installing your lug nuts with these. It can be easy to cross thread.

 

[SHAGGY101]

I will be cutting my own via waterjet (only cost me the Al << $200). I need to know if I would need to buy oversize thickness and then shave it down or will .5 or .375 work fine?

 

[Mxndrnks]

10mm is the thickest you can go and still safely use the OEM Lugs. Neither Spresso nor I have been able to source a longer lug for our rigs to go thicker.

I cant remember what suspension setup you are running. But, I would only recommend the 10mm spacer if you are running aftermarket UCA's, remote res shocks, and/or need to run chains.

Spresso was the first to run this size spacer and it was for chains. I don't really need to run chains, but wanted extra clearance around my TC UCA's and Radflo Remotes. With my current 295 width tire, I can go with out the spacer. But, I like a little extra room.

If you want to run a thinner than 10mm spacer, you could depending on your needs (ie, chains).

Hope this helps.

Please elaborate as several of the respected aftermarket suppliers sell 1"-1.25" spacers with no mention of the requirement to change lugs. I'm running 1" spacers and from my non mechanical engineer viewpoint feel their is plenty of lug to thread onto. I have not looked at my 1.25" spacers to determine if that will still be the case. With a 285, 33" tire I have no rubbing issues, I can't speak to a tall skiny 35 or a 315.

Are you talking about a pass through type spacer that uses only the factory lugs and not a secondary set like Slee/JTs?

 

[Trunk Monkey]

Yes, he's talking about a spacer that just slides onto current lugs and eats up their thickness in lug threads. The ones you're talking about have their own lugs and bolt to the factory lugs.

Ok, so you are saying that you would get no rubbing with your 295s (assuming 18" wheels) at full lock and full bump? I am running carl's UCAs and will be going with remote res. in the future. I talked to bluecruiser about his spacers and he talked as if that was the way to go, no fender or frame rubbing with his 295/75 R18 Nitto TGs. Hopefully Spresso and bluecruiser as well as laynnon I think can chime in on this. So would .375 work or is there just enough room with that extra 0.020"?

@ Jon, why did you decide on the 1" spacers?

TM covered it. The larger 1", 1.5" etc. are really wheel adapter spacers even though most just refer to them all as spacers.

You are correct that a 1" and larger can use the OEM lug. However, between1" and 10mm would require either a longer or shorter lug depending on how it attaches (an adapter or straight spacer).

To the op, regarding Bluecruiser...while he and I both run a 295 width, his TG's are almost .5-.75" wider than my BFG AT's. Both Bluecruiser and I went through a lot to get things dialed in right. Some of that had to do with the vendor sending out untested changes to products and a real lack of info about aftermarket UCA's and remote shocks. The Radflo remote is larger than other offerings and creates some challenge in installation and rubbing. In the end for me, Radflo stepped up and took care of me. I use a different mounting bracket then what others are getting from Metaltech. With everything set up right now, I have zero rub with my BFG at 295's with no spacers on. The rub that both Bluecruiser and i had issues with was more rubbing on the remote res.

Spresso pointed me to the 10mm spacers and then I in turn pointed Bluecruiser and laymann and a couple others...

 

[Mxndrnks]

Forgot to add, my tires are 295/75/16's. I would look at the dims on the Kevlar compared to TG's. But, as I posted above, if you are going remote shocks, go ahead with the spacer.

 

[SHAGGY101]

Thanks, wasn't sure if the larger diameter would matter or if it was just a width issue.

 

[bluecruiser]

I tried the 1.25in spacer with no body lift and found my front tires contacting the upper fenders at full compression. I believe Mxndrnks went that same route initially . I needed some spacer to clear the reservoirs, that's the only reason I tried a spacer. Then I was turned on to the 10mm spacer and I like this setup better. But I have a 1in BL now, as well. I just sent my shocks back to the vendor for a longer reservoir hose. I was still having very slight rubbing on reservoirs with current setup, but enough to be annoying and potentially an damage issue.

I'm not a fan of how far the 1.25in spacers made the tires stick out. I know some talk about liking the added "stability" of the wider track, but I think it's more visual and most likely doesn't yield any performance change.

What's the name of the place that makes the spacers?

I was looking to upgrade from OME to Radlo's but I'm starting to think the res's aren't worth the trouble.

 

[bluecruiser]

Buy from Radflo directly....they have new mounts now and are using longer hoses, I believe. Or get non reservoir shocks, still a huge upgrade from OME.

 

[Mxndrnks]

What's the name of the place that makes the spacers?

I believe it is Adaptec. But, I will post a direct link when I get home tomorrow.

Im running the same 10mm ones as Spresso (or he was) and mxndrnks from motorsport tech. I bought a set of 4 and just currently running the ones on the front to get my 315s off the UCA. My tires clear everything fine now after slightly adjusting the turn stops.

After two wheeling trips, my rear is still not rubbing so i have not put them on the rear. It took about 3 weeks for me to get my order after placing it. There were busy filling out other orders that had smaller bolt hole sizes or something.

If you decide you don't need the other two, I would be willing to take them off your hands....I plan on just doing the front to push out the wheels just a little bit.

Well i needed to put one on my tire mount for the bumper as the 35 is so wide that i could no longer use the hi-lift mount and it sat extremely tight against the vertical bars of the spare mount, haha.

Also, if you get 10mm spacers, there is still just a little bit of a lip from the drive flange up front to still center the wheel on the hub when you tighten the lugs.

Oh I see. Can you PM the exact ones you bought? I tried to get price some out on the site, but they wanted to know the center bore and a few other measurements I wasn't sure how to get. want to get it right the first time....

@ Jon, why did you decide on the 1" spacers?

Called Slee, Asked what he recommended for 35s (1" in rear and 1.25" in front) and ordered a set. We shall see if the 1.0" or 1.25" is too much with 315s and 1" body lift. I would go for the tall skinny 18s but cant justify the cost of rubber.
