Fitment and specs
- Thread size: 12x1.5
- Overall length (L1): 2.6 inches
- Knurl diameter (D1): 0.55 inch
- Extended length version of our 12x1.5 adapter stud
- Not compatible with our 2-piece conversion adapter studs
Press the stud in straight so the knurl bites evenly and the head seats flush against the back of the adapter plate. Before final assembly, test-fit your wheel to make sure the extra stud length clears the back of the wheel and your lug nuts, especially closed-end styles. Torque the lug nuts to spec using our torque reference chart and re-torque after 50 to 100 miles.
Common questions
When do I need the extended length instead of a standard stud?
Choose this 2.6 inch stud when a standard length stud does not leave you enough usable thread for your setup. Just confirm the added length still clears the wheel and does not bottom out inside closed-end lug nuts.
Will these work in my 2-piece conversion adapter?
No. These are not compatible with the studs used in our 2-piece conversion adapters. They are press-in replacements for adapters that run a 12x1.5 stud with a 0.55 inch knurl.
