Fitment and specs

  • Thread size: 1/2"-20

  • Finish: black
  • Application: older GM and Chrysler cars and trucks
  • Sold individually, priced per piece

Install with a 13/16" socket and start every nut by hand for a few turns to avoid cross-threading. Tighten in a star pattern to the spec for your vehicle in our torque reference chart, then re-torque after 50 to 100 miles of driving.

Common questions

Will these work with my wheels?
The nut seat has to match the wheel seat. Acorn style nuts use a tapered seat, and tapered, mag, and ball seats are not interchangeable, so check the lug holes on your wheels before ordering.

How do I confirm 1/2"-20 is my thread size?
1/2"-20 means a 1/2" stud diameter with 20 threads per inch, a size found on older GM and Chrysler vehicles. If one of your current lug nuts threads onto a stud smoothly by hand and matches this size, you are set.
