At Terra Firma Automotive, the Tomei Billet Crankshaft with full counterweight is the key to transforming your RB26DETT engine into a 2.8L stroker. This crankshaft is engineered to convert the pistons' reciprocating motion into rotary motion, driving your wheels with maximum efficiency. Designed for high-speed revolutions, it offers exceptional torsional and bending rigidity, as well as wear resistance to ensure durability under intense driving conditions.
With weights placed strategically on the arms surrounding the crankpin, the Tomei Billet Crankshaft improves the balance ratio. This enhanced balance reduces vibration and minimizes bending, which helps to prevent uneven bearing contact—crucial for maintaining engine stability and performance at high RPMs. Sharpened ends of the weights also minimize oil resistance in the pan, allowing for smoother engine operation.
To increase reliability, Tomei has also boosted oil supply from two crank journals, which strengthens the crankshaft’s resistance to bearing seizure. WPC treatment further enhances durability by preventing crank pulley seizing, ensuring long-lasting, efficient engine function. Precision-crafted using CNC machining and inspected with 3D measurement technology, the Tomei Billet Crankshaft is built to deliver unparalleled performance and accuracy.
For anyone serious about unlocking the full potential of their RB26DETT engine, this crankshaft is the foundation for a powerful 2.8L stroker build that’s ready to dominate both the track and the street.
