Determining Lug Bolt Length for Spacers:

Remove one lug bolt and measure the length from the end of the threads to the bottom of the seat, add the spacer thickness to the stock bolt length, this number is your new optimal bolt length. (Stock length + spacer thickness = new bolt length)


Hartmann Lug Bolt Install:

  • Confirm the lugs are the proper length by threading a single bolt in by hand and counting the rotations until seated, you should get 7 rotations.
  • Once seated rotate the wheel slowly to ensure the lug is not contacting any components on the inside of the hub.
  • Install wheels in the air, using the brakes to stop the wheel from turning and torque the lugs to the vehicle manufacturers specified value first in a star pattern, followed by a circle.
  • Re-torque the lugs after 1 week on brand new wheels.
