Two Piece US Made Wheel Adapters

Pair of 2 US Made Billet Wheel Adapters cut from 6061 T6 Billet Aluminum made in the USA

This listing is for two (2) wheel adapters and each adapter is two pieces so you would have enough to change the bolt pattern of two wheels.


Part #  =  USA-4156-5550E7-131

Quantity = 2

Vehicle Bolt Pattern  =   4x156

Wheel Bolt Pattern  =  5x139.7 / 5x5.5

Adapter Center Bore  =  131mm 1" deep only on back piece

Wheel Lip Ring = $ Extra Custom Order

Adapter Studs  =  12x1.5

Thickness  =  2" aka 50.8mm


The studs on your vehicle need to be trimmed down for installation of these adapters if they are longer than 1.25 inches.

You will need conical seat lug nuts in 3/4 hex to fit your vehicle for installation, we have them available but they are not included.

The bolts that holds the two pieces of these adapters together should be torqued to 60 to 65 pounds and I also recommend using the removable blue Loctite on the black bolts.

Pay particular attention that the lug nuts or studs from the vehicle do not touch the second piece of the adapter.

These Adapters Are Not Returnable


Custom Adapters with Other Specs Are Available.
