Wheel adapter studs 1/2" thread size with 2.6" overall length (L1). Knurl diameter (D1) is 0.55". They are not compatible with our 2-piece conversion adapter studs.

Fitment and specs

  • Thread size: 1/2"
  • Overall length (L1): 2.6", extended length
  • Knurl diameter (D1): 0.55"
  • Replacement stud for wheel adapters
  • Not compatible with our 2-piece conversion adapter studs

Install these like any knurled press-in stud: support the adapter plate, press the old stud out, and press the new one in square until the knurl seats fully. Once the wheel is mounted, torque the lug nuts to spec with our torque reference chart and re-torque after 50 to 100 miles.

Common questions

When do I need the extended length?
If your current studs do not leave enough thread showing for the lug nut to engage fully, the 2.6" overall length gives you more usable thread. Measure your old stud first: if it already runs 2.6" end to end with a 0.55" knurl, this is the direct replacement.

Do these work with 2-piece conversion adapters?
No. 2-piece conversion adapters take a different stud, so order the version listed for the 2-piece design if that is what you run.
