What are Wheel Spacers?

Bolt On

Customers typically widen the stance of a vehicle using bolt on wheel spacers. These types of wheel spacers are also commonly used to fix backspacing issues.  Unlike adapters, spacers will keep the same bolt pattern as the vehicle. Bolt on Spacers are available in two designs, hub centric and lug centric. This means they center on the hub of the vehicle while simulating the piloting lip on the face side.  Lug Centric would mean they are centered only by the lug nuts. ‘Bolt-on’ style bolt to the hub of the vehicle using the factory studs and provided lug nuts.  The wheel is then secured to the studs of the wheel spacer using the factory lug nuts already on hand.

Slip On

‘Slip-on’ style wheel spacers slide over the existing studs, so it is important to make sure that there will be enough thread left past the wheel spacer for secure installment of wheel. Otherwise, you will need extended wheel studs.  These slip-ons can also be hub centric meaning they will pilot on the vehicle’s hub and have a lip to pilot the wheels. In order for a lip to be simulated on any spacers while using a factory wheel, a measurement of the length of the hub flange must be taken to insure fitment.  than the hub of the vehicle. Although the minimum thickness for slip on style hub centric spacers running factory wheels will be around 12mm (in most cases) in order to clear the existing hub lip or ‘flange’ found in the center of the hub. The minimum thickness is 5mm for vehicles using aftermarket wheels with a larger center bore. Also Available with no lip.
