Bolt on Spacer

The PCD (Pitch Circle Diameter) is the diameter of the hub fixings through the centre of the hub. We have created a helpful guide should you require more information, you can find this under the guides tab at the top of the page.
The centre bore is the protrusion in the middle of your hub assembly, on most vehicles the protrusion of this lip is quite shallow (between 5mm and 15mm) although on some this can be as deep as 40-50mm. You will need to make sure that the protrusion of your hub lip is ATLEAST 3mm less than the thickness of the spacer you are choosing. For example, with a 20mm spacer your hub protrusion cannot be more than 17mm.
These are the fixings that you currently attach your wheel to the hub with. You will use either a nut (which screws onto a protruding threaded stud in the hub) or a bolt (which screws into a threaded hole in your hub)
The thread size of your original fixing, this needs to match your existing hub as we will supply fixings to attach the spacer to your hub assembly (BOLT ON SPACERS AND PCD ADAPTERS ONLY)
Wheel PCD Content
On most spacers we will provide an outer lip protrusion on the spacer to centre your wheel. You can choose the same dimension as your hub if you are using OEM wheels or are using spigot rings. You may require a different size centre bore to your hub if you are using an aftermarket wheel. We would usually work to a 0.1mm tolerance, if you are manually measuring aftermarket wheels, we suggest you use a device which works in 0.1/0.01mm increments.
These are the fixings that are supplied in the spacer or adapter, either a protruding threaded stud or a steel threaded insert. We do not supply the nut or bolt that secures the wheel to the fixing in the adapter.
The wheel you are using may require a specific type of fixing so be sure to check this.
As standard we preselect the same fixing as your hub (BOLT ON SPACER ONLY), although, you can change to a different fixing type if required.

If you do not require an outer lip or if it is not possible to have an outer lip, due to the depth of your original hub lip protrusion, you can select the option No.

You can choose a width from our standard sizes, although you can choose a specific size if required. You will need to measure the available gap in your wheel arch to make sure your wheel will not foul or protrude your wheel arch.
Our standard manufacturing timescale is 10 working days, if you require a quicker service we can offer a 5 working day turnaround time.
