I get the theory and I don’t want to debate small details. I read for hours about spacers before making the decision to go with them and while a ton of guys state this information as fact, I literally could not find a single verifiable article supporting this. Now, I’ll give it to you that what you’re saying seems logical, but I just can’t find the documents to back it. That’s all.

At the end of the day, go with what you like. I love the flush look it adds. Any minor change in performance, and I couldn’t detect any, has been well worth it. I get what you’re saying and I appreciate the input. I just don’t think it’s enough for people to turn away.

My biggest concern was how they would hold up to wheeling and I’ve been utterly impressed. Not a single issue at all. Spidertrax all the way.

Here is what 1.25" spacers look like on the 7" TRD Pro wheels with 265 70R17 Duratracs with no lift on an ORP. They fill out the wheel wells more and IMO look better with the C4 fab sliders. All mods in stages for me, and this is the running configuration of my rig before I spec and budget a lift and new wheels/wider tires.

At what cost you say? I had to trim the front bumper and relocate the liner and pull off the front mud flaps. I don't have the 55mph wiggle with the BORAs torqued to 90 ft lbs with blue loctite and maybe if you keep your tire pressures equal and check the torque on the spacers occasionally all will be fine with your ride as well. I don't see enough posts/classifieds/threads about folks buying used 4Runners or other 4WD vehicles and replacing the bearings due to spacers, so I'm not going to worry about it for the short duration that I plan to run this setup.

Why do it? Makes the truck look much beefier than without. We get compliments on the overall setup everywhere we go. YMMV.

I have been looking at spacers, I have a 18x9 rim with 275/70/18 all terrain tire, I think pushing them out further will look nicer.

I wanted to add when you lift your rig, your stock rims will look even more sunken in.

I have a 3 inch lift and am running stock trail rims, and 1.25 spacers push it pretty much flush with the fenders. I don't have any more mud/rocks hitting my fenders than without the spacer.

Now with TRD pro rims, 1.25 spacers pushes a little bit past the fenders due to backspacing and offset, but not enough to where you will notice rocks hitting your fenders either.

If you are going to install spacers, please follow directions. If it says 90 ft/lb torque, and to check it 500 miles later, please do it.

I torqued mine to 90 ft/lb per torque with red locktite and I used extended wheel lug nuts for the spacer to hub fitment. I left this alone after installation.

For spacers to wheel, I used OEM wheel lug nuts and torqued it to 90 ft/lb per torque, and I periodically use a torque wrench every so often and check it at 85 ft/lb per torque just to hear the click and to make sure my lugs are tight.

YOU DO NOT WANT TO OVERTIGHTEN THE LUGS on the spacer to wheel, because the lugs will strip out the aluminum teeth in the spacers or fatigue the studs themselves....thats why overtorquing the lugs is the most common cause of failure.

If you are getting wheel wobble, recheck all the lugs again.

There is probably a thread more suitable to this question, but the subject of offset has been opened here so I'm going to jump in.

Without debating whether increasing offset is harder on your wheel bearings, can anyone help me with the math to illustrate whether positive or negative offset provides more leverage on the hub or would the change in leverage be the same? I think for the purpose of this discussion we could go without including any effects caused by cornering, however if you have the math bring it.

My thought is if the leverage is the same either way, then an aftermarket wheel with a -12 mm offset would exert about the same leverage as a stock wheel at +15 mm. Not that it matters, but I do have brand new set of wheel spacers sitting in the garage.

Thank you

Run quality hub centric spacers. Proper torque. Check them every now and then. Don’t let anyone over torque the studs. I have had no issues and I’ve run quality spacers on many cars and trucks. I’ve even ran multiple track events in my S2000 on wheel spacers.

But everyone is entitled to their own opinion.

So the vehicle I’m looking to buy has had spacers on since new and the owner of it said that the wheel shake it has was caused by the spacers. I will be removing them as soon as I purchase the truck. Does anyone on the boards experience this issue? As I love how it looks I don’t want good looks to put extra wear on steering components

Great look on that truck. Love the look and how do you like those tires on the highway? Much noise or barely?

But that added sound "wears off" after a few hours of having them on. I kind of like the sound as its determined, not whiny. On the other hand, I don't get any better than 16.4 mpg with them, and I don't mind because I run 87 and its a buck cheaper than the 93 that goes in my other cars and bikes. Its also the coolest OWL tire for our rigs so if that makes a play for you like it does for me there is no other choice. Get em!

If the bearings were centered at the wheel mount surface - then it would be similar either way. The bearings are inboard quite a bit from the wheel mount surface. So a negative offset wheel moves further from an evenly loaded bearing. I don't know if the wheel bearings in these are annular or angular. Angular contact bearings can withstand a bit more thrust as a result of offset load than annular.

Thanks for the examples @Jetboy . I didn't think about the bearing not being on the wheel surface mounting plain. I just thinking of the wheel mounting point as being the place where all the magic happens.

I've never heard of spacers causing wheel shake. I'd be leery of a seller making that comment. Best to work a deal with him to remove the spacers prior to sale so you can see if the wheel shake goes away. Or not...

are those 1.25" spacer the ebay set? how are they holding up still running them ?

cheers

Nope . Motorsport tech/bora outta Sparks , Nv ! Makes all sizes

So my question is, I've been selling a lot of lifts for these trucks, 2/1 kits, 1" levelings, etc. and many are asking if the spidertrax 1.2" I sell, on stock wheels will cause any rubbing with these levelings or lifts installed. Will they?
