8x170 Ford Hub Centric Spacer

These hub centric wheel spacers are designed for Ford F-250/350 running hub piloted wheels with Flange style lug nuts. They will also work with aftermarket lug centric wheels, but are NOT required because aftermarket wheels in most cases have a larger center bore for ease of fitment and a larger amount of applications.

1.5" and 2" may require trimming OEM wheel studs to avoid contact with the backpad of the wheel. CHECK WITH A STRAIGHT EDGE BEFORE INSTALLING WHEEL. IT IS 100% UP TO THE INSTALLER/END USER TO CHECK THIS. IF THE STUDS ON THE HUB PROTRUDES PAST THE FACE OF THE SPACER, IT WILL EVENTUALLY CAUSE A FAILURE! If stud pockets are in the backpad of the wheel, trimming generally would not be required!

If you are unsure of which rear axle you have here is an easy way to tell. The Dana M275 is only optioned in 2017 and new trucks with the HD Towing Package. if you have a 99-16 Truck it will have a Sterling rear axle. 2017+ Truck owners, 350 Single wheels are standard with the Dana. 250 is an option. For you the easiest way to tell is to count the diff cover bolts.

DANA M275 Rear Spacers will be sent with a very thin, fragile lip due to the diameter and length on of the hub on this axle. The taper of the diameter of the hub is so large, the ring must be machined so thin it will not serve structural purpose on this axle specifically until it is installed on the hub for support to fill the very small gap between the hub and wheel.

12 Bolt Diff cover = Sterling
14 Bolt Diff cover = DANA m275

Spacers are sold individually!
