Nitto H-Beam Connecting Rods - Nissan CA18DET - Silvia / 180SX (S13)
Nitto's CA18 H-beam rods are a forged 4340 upgrade for the CA18DET in the early S13 Silvia and 180SX. They suit street and weekend track builds that need a stronger link than the factory rods without stepping up to an I-beam.
Nitto H-beams are made from double-melted 4340 forged billet, which removes more impurities than single-melted steel, and are machined as a one-piece forging. They use ARP 2000 rod bolts and silicon bronze pin bushes, and are aimed at the mid-level enthusiast or racer.
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)
- Doweled cap for accurate cap alignment
- Silicon bronze pin end bushes
- ARP 2000 rod bolts, with ARP Custom Age 625+ available as an upgrade
