A stud to end all stud needs. These ARP2000 studs share compatibility with the BP and B6 engines to offer a stronger material and a larger shaft diameter. They allow for a higher torque values than your standard OE studs or ARP HSK's.
Following the BP torque sequence, torque these in 3 equal steps to 90ft lbs.
- 30ft lbs on the first pass
- 60ft lbs on the second
- 90ft lbs as a final spec
ARP Torque Specs
- Final torque: 90 ft-lbs (ARP2000 material, stronger than the standard kit)
- Steps: 30 / 60 / 90 ft-lbs
- Lubricant: ARP Ultra-Torque on the threads and under the nuts/washers
- Sequence: follow the factory Mazda BP torque sequence
- Note: this is Fab9Tuning's Extreme Duty kit — always defer to the instruction sheet in the box if it differs.
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
Do I have to use ARP Ultra-Torque?
Yes. Every torque value above was developed by ARP using ARP Ultra-Torque lubricant, which is included in the kit. Using motor oil or moly paste instead will change the friction and give you a different (and inconsistent) clamp load at the same torque reading.
Can ARP studs be reused?
Yes. ARP studs can be reused as long as the threads are undamaged and they were not over-torqued. Clean and inspect the threads, re-lubricate with fresh ARP Ultra-Torque, and torque to spec.
What makes these 'Extreme Duty'?
They use ARP2000 material with a larger shaft diameter than standard head studs, allowing higher torque values and greater clamp load for high-boost builds.
