The Brian Crower BC5759 crankshaft is engineered for Audi and Lamborghini 5.2L V10 engine builds requiring extreme strength and high-rpm reliability. Manufactured from EN40B billet steel and rated for over 3000whp, this crankshaft is built for serious performance applications where durability and oiling control are critical. Each crank is stress relieved, shot peened, magnaflux inspected, and nitrided through a multi-step heat treatment process for enhanced strength and long-term performance. Fully profiled counterweights help reduce windage through the crankcase, decreasing oil resistance for improved rpm potential. This crankshaft features straight-shot, priority main oiling and requires internal balancing during assembly. Brian Crower also specifies ATI Super Damper #918659; the OEM external damper should not be reused.
