• Thread size: Kits in this range include M12 x 1.25, M12 x 1.5 and M14 x 1.5. The thread must match your wheel nuts.
• Length: Extended ARP kits are listed by length, such as 1.75in, 2.535in, 2.85in and 3.0in. Choose a length that suits your wheel and any spacer you run.
• Knurl: The knurl must suit the stud hole in your hub.
• Pack quantity and position: Kits come in 4 or 5 packs, and some are specific to one axle, such as the front kit for the Celica ST162. Order enough studs for every wheel you are changing.

Wheel studs are pressed into the hub, so the old studs must be removed first. You will need wheel nuts with the matching thread. Tighten the wheel nuts to your vehicle manufacturer's specification. If you use spacers, confirm there is enough thread engagement with the spacer fitted.

Note: Wheel studs are safety-critical parts. Installation by a professional is recommended.

Do I need extended wheel studs with wheel spacers?
Spacers push the wheel further out from the hub. Longer studs may be needed to keep enough thread engagement for the wheel nuts, so check your spacer type and the stud length before ordering.

How do I know which thread size I need?
Each product title lists the thread size, such as M12 x 1.25 or M14 x 1.5. Match it to your vehicle's chassis code and your wheel nuts.

Do these kits include wheel nuts?
These are wheel stud kits, so check each listing's contents. Wheel nuts are available in our Wheel Nuts collection.

How many studs come in a kit?
Kits are sold in 4 or 5 packs, as listed in the product title. Order one kit for each wheel you are changing.
