Installation is of critical importance with wheel adapters.

Professional installation is strongly recommended.

Slip fit the adapter on the wheel and the vehicle before you bolt anything on to ensure that you have proper fitment.

These adapters are not returnable.

Mating surfaces must be clean and free of rust and obstructions allowing for the adapter to sit flat on the rotor, and the wheel flat on the face of the adapter.

Make Sure the lug nuts or studs from the vehicle do not touch the back of the wheel.

Torque by hand, do not use impact gun for installation.

Improper Installation Voids All Warranties.

Bolt Patterns

Bolt patterns must be correct, if you are not sure, please get help.

The bolt pattern of the vehicle comes first in the listing and the wheel bolt pattern is listed after the word "to".

There is no such thing as a universal wheel, it is what people call wheels that have two bolt patterns, but there is a possibility of 10 or more.

3, 5 and 7 lug bolt patterns measure differently than 4, 6, or 8 lug

Vehicle Studs

If the studs on your vehicle are longer than the adapter is thick you may need to trim them down so they do not touch the back of the wheel.

Factory lug nuts are often too big to recess in an adapter so they may need to be replaced.

Studs / Lug Nuts

These wheel adapters require a conical seat lug nut or bolt.

One set of open ended conical seat bulge lug nuts are included with the adapters.

The lug nuts included will be in the same size as the studs in the adapter unless otherwise requested or advertised above.

Different wheels require different kinds of lug nuts, make sure you get the proper lug nuts for your wheels in the right size to fit the studs in the adapter.

Factory bolts from Mercedes, VW and Audi have a radius seat (also called ball seat) lug bolt. Radius seat lug bolts are Not compatible with these adapters that require a conical seat they Must be replaced with a conical seat fastener or failure can occur. 

Custom built adapters are available that accept radius seat bolts by special request at additional cost.

Center Bore

The center hole of the adapter must be large enough to fit over the hub of the vehicle. It can be larger, which is called lug centric, where the conical seat lug nuts center the adapter on the hub.


Hubcentric refers to an adapter where the center hole of the adapter perfectly fits over the hub sticking out on the vehicle.


Wheel centric is available for extra cost in most applications.

Hub and wheel centric is the best and closest to factory fit that you can get which also adds extra strength.

Wheelcentric is optional in most cases but If you have wheels that require a radius seat lug nut, it is strongly recommended.


All adapters are also spacers because they require some thickness to be able to bolt onto the vehicle and then hold the wheel.

The minimum thickness we make is 19 mm a.k.a. 3/4 inch and we go up to 5 inches thick.

Installing Two-Piece Adapters

All the above still applies, but with a two piece adapter Make Sure the hub, studs or lug nuts from the vehicle do not contact the second piece of the adapter or it will cause failure.
Open ended 3/4" hex conical seat lug nuts, short enough to not touch the second piece of the adapter are required to fit the vehicle. (Not included)

The black bolts that hold the two pieces together should be torqued to 60 to 65 foot-pounds and I also recommend using blue removable Loctite on these bolts.
Do Not Use Impact Gun to tighten adapter bolts/lugs, torque by hand.


The pictures are of stock adapters and may not look exactly like what you get due to differences in bolt patterns and center bore sizes.

You will receive the item as described in the written description of the listing.


Our prices are higher than many other sellers with similar products because they are just that, similar products.

The cheap wheel adapters you see are made in China.

We are a US manufacturer based in San Bernardino California where we use US sourced billet aluminum providing the best materials for construction of our wheel adapters.

The US sourced aluminum that we use for construction is superior to that from China and it costs more for labor in the US which is why our wheel adapters cost more.


Beware of unscrupulous sellers of wheel adapters (there are many) who would imply or even straight up lie by saying that their adapters are US-made, but they're Chinese imports, these are truly US-made wheel adapters made by US citizens from US sourced aluminum in our machine shop in San Bernardino California
