Made in the USA, these are the same studs and lugnuts that NASCAR, IMSA and World Challenge teams use. Machined to strict tolerances, these studs are miles apart from factory studs or ARPs. We like the long knurl on these as you can literally toss the lugnut on and send it home with the Ugga Dugga machine without cross threading.
Wheel stud applications are based on FACTORY hub flange sizes; if you're using aftermarket hub flanges or bearings check the sizing on your studs before ordering. Some of the RockAuto variants use different stud sizing than factory (like all 4 corners the same diameter).
Lug nuts can be ordered in endurance yellow or orange (the black phosphate are still back ordered going on a year as of December 2021); yellow are M14x1.5, orange are M12x1.5. We also have a more affordable alternative for M12x1.5 lug nuts, here:
Studs & Lug nuts are sold as corner units (4 pieces), if you just need singles (or x5) contact us and we can get you fixed up.
