Nitto I-Beam Connecting Rods - Mitsubishi 4G63 - Lancer Evolution IV–IX (CN9A / CP9A / CT9A)
Nitto I-beam connecting rods for the Mitsubishi 4G63T in the Lancer Evolution IV to IX. They are built for engines that go beyond intermediate power, from big-turbo street cars to drag and circuit builds.
Choose the rod length to suit your build: 150 mm is the factory length for the standard 88 mm stroke, 153 mm suits Nitto's 2.2L (94 mm stroke) combination, and 156 mm is a longer option for custom combinations, matched to your piston's compression height. All use 3/8" ARP 2000 bolts.
Nitto I-beam rods are machined from one-piece forged 4340 billet round stock and are intended for builds that go beyond intermediate power levels. The single-piece billet keeps the grain flow uniform for strength, and each rod comes with ARP 2000 bolts and silicone bronze pin bushes. Step up to the V2 rod for the most extreme builds.
Note: Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.
