A 2.8-liter RB stroker combination requires connecting rods matched to the longer crankshaft stroke. The Tomei Forged H-Beam Connecting Rod Set (part number TA203A-NS05B) is designed for Nissan RB26DETT and RB25DET engines using a 77.7 mm stroker crank, with a 119.50 mm center-to-center length (2.0 mm shorter than the standard 121.50 mm rod) to maintain correct piston geometry.
Forged from SNCM439 material and finished in an H-beam configuration, these rods provide a strong balance of rigidity and controlled weight for higher-displacement, higher-load applications. The through-bolt design improves big-end stiffness and helps resist deformation under elevated cylinder pressures, while ARP L19 fasteners deliver high tensile and fatigue strength. At approximately 525 grams each, the rods are engineered as a durable component for serious 2.8 L builds rather than an ultra-lightweight racing piece.
This set is intended specifically for RB26 and RB25 engines being converted to 2.8 liters with a longer-stroke crankshaft and requires matching pistons and professional assembly. At Terra Firma Automotive, we supply this genuine Tomei Forged H-Beam Connecting Rod Set as a core internal component for stroker projects. Whether the goal is stronger mid-range torque or greater overall power capacity, these rods deliver the material quality and dimensional accuracy associated with Tomei. Choose Terra Firma Automotive for authentic Japanese engine internals that support capable 2.8 L RB builds.
