Understanding the 8x170 Bolt Pattern

- Standardization: By introducing a unique bolt pattern for the Super Duty lineup, Ford created a clear distinction between its heavy-duty and light-duty trucks.
This change was well-received by truck owners who required vehicles capable of handling demanding tasks, such as towing and hauling.
Implications for Vehicle Owners
For Ford truck owners, the adoption of the 8x170 bolt pattern means:
