those are lugcentric wheel adapters which can cause vibration while driving, i had a set like those for about 2 months then the vibration got annoying and finally bought a set of spidertraxx and no more vibration. the hubcentric adapters have a lip that the wheel sits on and the adapter fits snug around the hub which will center the wheel. marlin crawlers also make some hubcentric that are decent for about the same price as the spidertraxx. i would stay away from the cheaper ones and get the right ones the first time so you don't end up like me and have a extra set just sitting the garage that i can't use. good luck.

I didn't even notice those are lugcentric. The ones I had were hubcentric. I agree, do it right the first time.:tu:

Any other wheel adapters to trust besides Spidertrax?
Don't waste your time and money on a cheap product. If you're buying wheel spacers/adapters, go with a company that has the best reputation for the product. Spidertrax makes the best wheel spacers available.

Wheeler's Offroad sells them for one of the best prices I've ever seen new, $97/pr of 1.25" Spidertrax.

Stop spreading FUD. An adapter is an adapter, and either hub- or lug-centric will work just fine as long as the part uses the correct interface between the adapter and the wheel.

If your wheels are hubcentric, you need adapters with a centering ring on the outside.

If your wheels are lug-centric, you don't need the centering ring, but you can still use it with most wheels.

If your wheels have a flat face on the lug nuts, and a corresponding flat face on the wheel, they are hub centric. These wheels fit snugly over a raised ring (or cone) on the hub. The stock, 5-spoke, 16" wheels are hub-centric.

If your wheels have a taper on the threaded end of the lug, and a corresponding taper on the wheel, they are lug centric. They may also fit over a centering cone, but the lugs will ultimately center the wheel. Most aftermarket wheels are lug-centric, and will fit a centering cone as the center bore is machined true.

I have been running lug-centric wheels, with lug-centric adapters, for the better part of a decade, with about six of those years on 35x12.5R16 AT/KOs mounted on 16x8 AR Outlaw II wheels. If they aren't balancing correctly on the truck, the problem is most likely to exist somewhere between the wrench and the garage floor.

To date, I am still using 1.5" aluminum lug-centric adapters on a rear axle with Dana 60 front hubs, and the same wheel/tire combo...no problems. I hung the old 1.5" steel lug-centric adapters on the wall a couple years back when I went to a long-travel front and no longer needed the additional width to clear the tires. The only times I've ever noticed a balance issue are when there's gunk in the rim, I've thrown a weight, or there's a nail/screw/whatever lodged in the tire.

Spidertrax does make very nice spacers. So does Fred, so did AOR (the guys that made my steel spacers), so can any company with a lathe and a CNC mill. Just be certain that you have ordered the correct parts for your wheels (including metric threads with correct pitch to match what you have now), and that you have installed them properly, with sufficient thread engagement!

The parts in the first link will be just fine, if you have lug-centric wheels...they are identical (or should be!) to the two pairs of spacers I have used/am using.

I'd put my second set up for sale, but they're awfully handy for setting in new lugs, among other things, and they're steel, so if I accidentally drop them, I worry about the concrete, not the spacer :lol:...
