At Terra Firma Automotive, the Tomei Forged Crankshaft for the RB26DETT engine offers exceptional performance for those seeking to build a 2.8L stroker engine. Engineered with precision, this 8-counterweight crankshaft converts the reciprocating motion of the pistons into the rotary motion that drives the wheels, providing the essential power transfer needed for high-performance builds. Crafted for maximum torsional and bending rigidity, the Tomei crankshaft ensures durability at high speeds while reducing wear, making it ideal for engines subjected to extreme conditions.
The 8-counterweight design enhances the balance ratio by countering the inertia of the pistons’ up-and-down motion and the crankpin’s rotational inertia. This results in reduced vibrations and minimal bending, which helps prevent uneven bearing contact—essential for maintaining the crankshaft’s integrity during high-rev performance. The precision engineering of this crankshaft further optimizes efficiency by sharpening the weight ends, reducing oil resistance in the oil pan and ensuring smooth operation.
Increased oil supply is another standout feature of the Tomei crankshaft. By supplying oil from two crank journals, it significantly improves resistance to bearing seizure, enhancing the longevity of your engine components. With WPC treatment for superior seizure resistance and precision CNC machining combined with 3D measuring inspections, Tomei guarantees top-tier quality and accuracy. The Tomei Forged Crankshaft delivers the strength, balance, and precision your RB26DETT needs for next-level performance.
