When tuned, you get a higher combustion pressure, either when you expose your motor to charge pressure or if you increase the compression of a suction motor.

ARP bolts, are hot-rolled, specially-cured bolts with a traction that no other bolts outperform, making it the ultimate tool to hold a cylinder head in place when tuning its engine.

ARP bolts, combined with multi-layer steel gaskets, are a perfect long-lasting solution that can be used again and again, even if you disassemble your engine.
