The installer assumes all responsibility to ensure the adapters are installed properly using the appropriate hardware.
Please ask if you have any questions, we're here to help!
Important Notes:
  • Installation should only be performed by a trained professional.
  • Vehicle compatibility, if listed, is used to match the vehicle's bolt pattern with the adapter "vehicle bolt pattern" only.
  • You will need two sets of lugs nuts to use these adapters.
    - One set of open end lugs to bolt the adapter to the vehicle. The vehicles factory lugs are not compatible.
    - One set of the appropriate lug nut style with the "adapter stud thread size" listed above to bolt the wheel to the adapter.
  • The adapters are shipped with open end lugs on the studs, these would be used to bolt the adapter to the vehicle if the thread size is correct for the vehicle.
  • Only approved lug nuts can be used to bolt the adapter to the vehicle, factory lug nuts cannot be used.
  • Lug nuts on the adapters and wheels must be properly torqued when installing.
  • Never use air tools, always install by hand.
  • Some vehicles may require modifications to make the adapters work properly.
  • Be aware that the studs on the vehicle cannot stick out past the face of the adapter, you may need to modify them by grinding/cutting/trimming.
  • If your wheels have sufficient sized and placed pockets on the backside between the lug holes, you may not need to modify the studs.
  • If there are clips or retaining rings on the vehicle's studs they must be removed.
  • Always ensure that there is no gap between the spacer and the back of the wheel when installed.
  • We make no promise or guarantee that this item is compatible with your vehicle or wheels.
  • Please verify this is the correct application for your vehicle before ordering, we only guarantee you receive what is described above
  • Adapters that have been mounted to a vehicle and/or wheels cannot be returned for exchange or refund.
  • Ask if you have any questions or need assistance with your purchase, we're here to help!
  • The picture of the item is for general style reference only, it may not be the item that is listed. The item description will show the exact details.
HS6550-78-13L

Five lug bolt patterns are measured differently than four, six and eight which would be center to center of opposing hole or stud. Five lug is measured center of hole/stud #1 to the outside edge of hole/stud #3.

The most accurate way is to use a bolt pattern gauge, available for purchase here.
