The Manley Performance Turbo Tuff Pro Series I-Beam Connecting Rod Set (Part #14411R6-6) is purpose-built for high-horsepower Nissan RB25DE / RB25DET / RB26DETTs, covering 1989-2002 model years. Engineered for serious forced-induction builds — from street/strip GT-R builds to full-race time attack machines — these rods deliver the strength and reliability needed to survive extreme boost levels and high-revving conditions. If you're pushing the limits of your RB26, these are the connecting rods trusted by professional tuners and engine builders worldwide.

Key Features & Benefits

• Turbo Tuff Pro Series I-Beam Design — The I-beam profile provides an optimal balance of weight reduction and tensile strength, minimizing rotating mass while maximizing durability under extreme boost and RPM.
• ARP 625+ Fasteners Included — Each set includes premium ARP 625+ (Custom Age 625+) rod bolts, rated for over 260,000 PSI tensile strength — the gold standard in high-performance engine fasteners for peace of mind at high power levels.
• High-Strength Steel Construction — Forged from premium 4340 aircraft-quality chromoly steel, these rods resist bending, stretching, and fatigue far beyond OEM connecting rod limitations.
• Precision CNC Machined — Each connecting rod is CNC machined to tight tolerances, ensuring consistent weight matching across all six rods for smooth, balanced engine operation and reduced vibration.
• Shot-Peened & Stress-Relieved — Manley's proprietary shot-peening process relieves internal stress and greatly enhances fatigue life, critical for sustained high-boost and high-RPM duty cycles.
• Weight-Matched Set — All six rods are weight-matched within a tight tolerance to ensure perfect rotational balance, reducing bearing wear and prolonging engine life.
• CARB Compliant — Meets California Air Resources Board (CARB) compliance standards, making these rods legal for use in CARB-regulated states.
