Nitto H-Beam Connecting Rods - Nissan RB30 - Commodore (VL) / Skyline (R31)
Nitto's RB30 H-beam rods are a forged 4340 upgrade for RB30 engines from the VL Commodore and R31 Skyline, in SOHC form or with a DOHC head. They suit turbo street cars and mild drag builds that need more strength than the factory rods.
Nitto H-beams are made from double-melted 4340 forged billet and machined as a one-piece forging. They run 7/16" ARP 2000 rod bolts and silicon bronze pin bushes, giving a strong, affordable rod for mid-level builds.
Note: Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.
Features
- Double-melted 4340 billet steel, one-piece forging
- X-ray and sonic grade tested, quenched, heat treated and shot peened (38 HRC)
