Fitment and specs
- Thread size: 12x1.5
- Overall length (L1): 2.2 inches
- Knurl diameter (D1): 0.55 inch
- Fits our 4, 5, and 6 lug wheel adapters that come with 12x1.5 studs
- Does not fit adapter part numbers 5450-5450M-BL or 5450-5450M-BK
- Not compatible with our 2-piece conversion adapter studs
The knurl creates the interference fit that holds the stud in the adapter, so press it in straight until the head seats flush against the back of the plate. Check your adapter part number against the two exceptions above before ordering. After the wheel goes back on, torque the lug nuts to spec with our torque reference chart and re-torque after 50 to 100 miles.
Common questions
Will these fit my 2-piece conversion adapter?
No. These studs are sized for our standard 4, 5, and 6 lug wheel adapters that come with 12x1.5 studs. The 2-piece conversion adapters use a different stud, so order from that listing instead.
How do I verify the fit before ordering?
Confirm your adapter came with 12x1.5 studs, your old stud measures 2.2 inches overall with a 0.55 inch knurl, and your adapter is not 5450-5450M-BL or 5450-5450M-BK, since those two take a different stud.
