ARP Extended Wheel Studs: Notice for the 7719 studs we've sourced a private label ARP chromoly stud at a higher cost. This cost is not forwarded to you but we're making you aware in the event you end up with a mixed set.
With a tensile strength of 190,000 psi, these heat-treated, Cadmium-plated 8740 chrome moly ARP wheel studs are a necessity for any car with aggressive fitting wheels or participating in competitive racing. They easily handle tremendous acceleration shock loads (shear) and lateral forces (elongation).
NOTE: Each package contains 4 wheels studs (one corner).
ARP Torque Specs
- Lug nut torque: ARP does not publish a lug-nut torque for wheel studs — torque your lug nuts to the wheel or vehicle manufacturer's specification
- Re-check: re-torque the lug nuts after 50–100 miles of driving
All torque values assume ARP Ultra-Torque fastener assembly lubricant (included in the kit). Do not substitute motor oil — ARP notes it produces higher friction and inconsistent clamp load.
FAQ
What torque do I use on the lug nuts with ARP wheel studs?
Follow the wheel manufacturer's spec (for reference, Mazda lists 65–87 ft-lbs for NA/NB Miatas — that is Mazda's figure, not ARP's). Always re-torque after 50–100 miles.
