Tomei offers 147mm or 150mm connecting rods for the 4G63 Evo 1-9 2.2L or 2.3L. These H-Beam rods are lightweight, highly rigid at the big end, and feature rib-shaped caps. They are designed to enhance oil supply to the small end through two ports.

More Info:
These connecting rods transmit the pistons’ reciprocating motion to the crankshaft, converting it into rotary motion. High strength is essential to handle the pistons’ pressure. They are torsion-resistant and lightweight, matching the strength of I-beam designs. The slant design improves rigidity at the big end, while through-bolts and a smooth shoulder shape enhance overall rigidity. Two ribs increase the connecting rod caps’ rigidity, preventing bearing failure from big-end deformation, further supported by large diameter dowel pins. Increased oil supply prevents seizing failure, and offset placement boosts strength against high-revolution pulling. Compared to general ARP2000, these connecting rods have higher fatigue and tensile strength, ensuring a firmer big-end joint.
