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.
Installing Two-Piece Adapters
The bolt pattern of the vehicle comes first in the listing and the wheel bolt pattern is listed after the word "to".
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 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.
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.
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 because they are usually cheap, inferior wheel adapters 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 and more costly than 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
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.
