Does the W0406-15 require longer wheel studs?

In most cases the factory studs provide sufficient thread engagement at 15mm, but always verify thread engagement matches the stud diameter before installation.

What does hub centric mean for the W0406-15?

Can I use the W0406-15 with my factory lug nuts?

In most applications the factory lug nuts will work, but always confirm proper thread engagement and seat type before driving.

Install Instructions

  1. Raise and safely support the vehicle, then remove the wheel.
  2. Clean the hub face to remove any dirt or corrosion.
  3. Place the Whiteline W0406-15 spacer onto the hub, aligning the hub centric bore.
