The TB48 billet crankshaft with a 105 mm-145mm stroke and knife-edge design (STD journal) is engineered for high-performance applications, offering a balance of increased displacement and high-RPM efficiency. Crafted from aerospace-grade 4340 billet steel, it delivers exceptional strength and fatigue resistance under extreme conditions. The knife-edged counterweights reduce windage losses inside the crankcase, improving engine response and power output at high RPM. Precision CNC machining ensures optimal balance and accurate fitment, while standard journal sizing allows compatibility with OEM-style connecting rods and bearings. The crankshaft typically includes drilled oil passages for enhanced lubrication, along with surface treatments such as nitriding, shot peening, and stress relief to extend durability and longevity. This makes it an ideal choice for custom TB48 builds focused on performance and reliability.
