A set of six forged 4340 I-beam connecting rods for the Nissan RB25DET and RB26DETT in R32 to R34 Skylines and the Stagea. They are aimed at builds that go past intermediate power levels, where you want a tough, proven rod without the cost of Nitto's flagship V2.

Note: Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.
