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.
Installed 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 must be correct, if you are not sure, please get help.
If you purchase the wrong bolt pattern it will cost you for postage and handling to get them exchanged.
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
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.
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 for the person that wants the best and closest to factory fit that you can get, or you want extra strength, then wheel centric is optional.
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
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
WarrantyImproper Installation or alteration Voids All Warranties.
We offer a limited lifetime warranty on our US-made wheel adapters.
This warranty covers the aluminum construction of the adapter, if it should ever fail we will replace the defective part.
This warranty is limited to part replacement only, user agrees to assume all other responsibility and or liability arising from use of this product.
Wheel studs are a wear part, and are replaceable in the adapter, there are many ways to damage them that have nothing to do with construction so wheel studs are not covered under this warranty, if you need stud replacements we have them available for sale online.
NO Refunds - Exchange Only Buyer pays shipping both ways.
NO Returns after 30 days
If you purchase a set of adapters that you no longer need or were the wrong application, and you want a refund, you pay to ship the adapters back to us and there is a 20% restocking fee for refunds of items returned in new condition.
Adapters that have been bolted to the vehicle are not returnable, only parts in brand-new condition are accepted for refund or exchange.
Adapters that are improperly packed for the return and therefore arrive damaged will not be accepted for refund or exchange, please be sure to package them well and put something between the adapters when shipping.
The process for exchange is the same as for refunds except for most items it is an additional $20 to cover shipping and handling to a US address for the return instead of 20% restocking.
Thank You And Have a Blessed Day
