Installation is of critical importance with wheel adapters.
Professional installation is strongly recommended.
Installed adapters are not returnable.
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.
3, 5 and 7 lug bolt patterns measure differently than 4, 6, or 8 lug
NEVER rely on the stamp on the wheel for bolt pattern, it is Wrong more than right.
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 in the same size as the studs in the adapter unless otherwise requested or advertised above.
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.
You will receive the item as described in the written description of the listing.
Our prices are higher than many other sellers because they are usually cheap, inferior wheel adapters made in China.
The US sourced aluminum that we use for construction is superior and more costly than that from China and it costs more for labor in the US which is why our wheel adapters cost more.
WarrantyImproper Installation or alteration Voids All Warranties.
We offer a limited lifetime warranty on our US-made wheel adapters.
NO Refunds Exchange Only
NO Returns after 30 days
Adapters that have been bolted to the vehicle are not returnable, only parts in brand-new condition are accepted for exchange.
Adapters that are improperly packed for the return and therefore arrive damaged will not be accepted for exchange, please be sure to package them well when shipping.
Thank You And Have a Blessed Day
