Before ordering
PCD names and steering-wheel mounting patterns are not universal, so measure your wheel and hub before purchasing. This adapter does not include a steering wheel, hub kit, vehicle-specific boss, airbag components, wiring, or other vehicle hardware. Compatibility with a particular vehicle or hub cannot be confirmed from the available specifications alone.
Installation and safety
Have the adapter installed or checked by a qualified technician, especially when it is used in a road vehicle. Follow the steering wheel, hub, and vehicle manufacturer’s instructions for fastener selection and torque. Confirm that the wheel sits flush, the bolts engage correctly, and the steering and safety systems operate properly before driving.
