ARP is the world leader in fastener technology.
Makers of the finest fasteners in the market, especially for BMW engines, ARP is the choice when you want the highest reliability possible.
ARP is used on ALL our VAC built engines.
- Protects the threads in your S14 engine block.
- Significantly stronger than other stud kits
- Trusted around the world by top race teams
- A must for turbo or supercharged applications
- ARP Head Bolt Set does NOT require re-torque of cylinder head after heat cycle.
- ARP Head Stud Kit DOES require re-torque of cylinder head after heat cycle. You'll need to remove the camshafts, camshafts box and redo the timing.
We highly reccomend using ARP Head Bolts rather than Head Studs, as they do NOT require re-torque after heat cycle. This requires less engine disassembly and reassembly, saving time and labor hours.
