At Terra Firma Automotive, the Tomei Billet Crankshaft for the RB26DETT engine is designed to maximize performance for those building a 2.6L powerhouse. This full counterweight crankshaft delivers unmatched precision by converting the pistons' reciprocating motion into the rotary motion needed to drive your wheels. Crafted for high-speed revolutions, the Tomei Billet Crankshaft offers superior torsional and bending rigidity, ensuring durability under extreme conditions.
The full counterweight design enhances the balance ratio by counteracting the inertia of both the piston movement and crankpin rotation. This reduces vibration and minimizes bending, preventing uneven bearing contact, which is critical for maintaining engine integrity during high-rev scenarios. With its sharp, weight-reducing design, this crankshaft minimizes oil resistance in the pan, further optimizing performance.
Additionally, Tomei has increased oil supply from two crank journals, offering improved resistance to bearing seizure and enhancing long-term engine reliability. The WPC treatment provides extra protection against crank pulley seizing, ensuring the crankshaft operates smoothly and efficiently under stress. Precision is key with Tomei, and this crankshaft is meticulously crafted using CNC machining and 3D measurement inspections for unparalleled accuracy.
For those looking to push the limits of their RB26DETT engine, the Tomei Billet Crankshaft delivers the strength, balance, and precision needed to achieve superior performance and reliability on the road or track.
