Drill Guide SD60 to 6 on 5.5

Shipping calculated at checkout.

This handy drilling guide is used to mark the hole centers when converting the wheel stub bolt pattern on a Ford Super Duty front axle wheel hubs from 8 bolt on 170mm to 6 bolt on 5.5” bolt circle diameter.

Simply place the drilling guide over the stock wheel studs, then use the small holes & a punch to mark the exact centers of the new 6 on 5.5” lug pattern.   Drill your wheel hubs to your new desired wheel stud size & press into the wheel hub.

Machine the diameter of the hub is required going to a smaller lug pattern. We do not provide details on what to do. You can see in the pics for example. 

No guessing!  Ensure your new wheel stud pattern is concentric to the wheel hub.
