Overview 

The TB48 billet crankshaft with a 98 mm stroke and knife-edge counterweights is a premium performance component designed for high-output Nissan TB48 engine builds. Precision CNC-machined from high-strength 4340 billet steel, it offers exceptional durability, rigidity, and resistance to fatigue, making it ideal for forced induction or high-RPM applications. The knife-edge design reduces windage losses and rotational mass, allowing the engine to rev more freely and efficiently. This crankshaft retains the standard journal size, ensuring compatibility with OEM or aftermarket rods and bearings. It undergoes extensive finishing processes—including stress relief, shot peening, nitriding, and magnaflux inspection—to ensure structural integrity and consistent performance under extreme conditions. Engineered for reliability and performance, this billet crankshaft is a cornerstone for serious TB48 builds targeting increased displacement and sustained high-load operation.
