Application details and restrictions
| Application | Thread | Length | Restrictions |
|---|---|---|---|
| Compatible standard Wilwood ProStreet and Drag hubs | 1/2-20, full thread | 1.75 inches | Confirm hub design, stud seat, wheel thickness, lug-nut engagement, and brake-system instructions before ordering |
This is a universal, dimension-based service part and does not carry year-make-model fitment. It is not a substitute for every 1/2-20 wheel stud; the hub and wheel installation must match Wilwood's stated component and dimensional requirements.

About Wilwood
Wilwood Engineering manufactures brake systems and service hardware for street, competition, off-road, and specialty vehicles. Wheel fasteners must be matched to the exact hub, wheel stack, thread engagement, and service procedure.
Related Parts
- Use only the compatible Wilwood hub, wheel nuts, and brake-system hardware specified for the complete installation.
- No related store product is linked because wheel and hub compatibility must be confirmed by dimensions and the exact brake package.

- Have a qualified technician remove the hub or obtain the access required by the current Wilwood service procedure.
- Inspect the hub stud bores, mounting surfaces, wheel, and lug nuts; replace damaged components rather than forcing a mismatched stud.
- Install and seat each stud using the method specified for the exact Wilwood hub without striking or loading the threaded section.
- Confirm equal seating, correct projection, full lug-nut engagement, and adequate clearance around the brake and wheel assembly.
- Reassemble the hub and wheel, then tighten wheel nuts using the vehicle, hub, and wheel manufacturer's specified sequence and torque.
- Reinspect stud seating and wheel-nut torque after the initial service interval required by the wheel and hub instructions.
