ARP strives to produce the strongest, most reliable, and consistent hardware to meet your racing demands. ARP2000® bolts are cold forged to ensure molecular integrity, heat treated prior to thread rolling and machining, and designed to exceed the OEM Torque to Yield (TTY) bolts in both strength and durability.
Ever wonder why you need to upgrade connecting-rod bolts, cylinder head studs, or other internal engine hardware? As you demand more horsepower and torque out of an engine it is typically accompanied by higher cylinder pressures, higher RPM running, and greater loads. All these contributing factors can stretch hardware. Metals are like a spring — put a load on them and they will stretch. Double the load and they will stretch double.
Heat treatment is a broad term for the process of heating and cooling metals, while carefully controlling their phase. This can be done by processes such as annealing in vermiculite, normalizing in air, quenching in water or oil, and a number of other techniques.
