Modalworks M177 H-Beam Connecting Rods The Modalworks M177 H-Beam Connecting Rods are engineered for extreme durability and high performance, designed specifically for the Mercedes-AMG M177 4.0L V8 engine. These rods leverage advanced features to meet the demands of high-horsepower and high-RPM applications, ensuring reliability in the most challenging environments. Key Features: H-Beam ConstructionThe H-beam design is renowned for its strength and lightweight efficiency, enabling the rods to handle extreme forces while reducing weight for improved performance. Proprietary Forging MaterialEach rod is manufactured from an oversized forging to ensure proper grain flow, enhancing strength and eliminating surface imperfections. Carrillo's proprietary "Carrilloloy" material is enriched with specific ratios of chrome, nickel, molybdenum, and vanadium, offering an optimal balance of strength and ductility. This material is independently inspected and certified for consistency, delivering exceptional durability under extreme racing conditions. Coupled with precision machining, this ensures tight tolerances and reliability throughout its lifecycle. Precision FastenersModalworks rods employ custom-engineered fasteners from CP-Carrillo. Manufactured with high strength steel (220,000 UTS) and a patented thread design, these fasteners deliver exceptional tensile strength and fatigue resistance. Every batch undergoes rigorous testing, including destructive testing for ultimate tensile strength and fatigue, ensuring unmatched reliability and consistency. Finite Element Analysis (FEA)Utilizing state-of-the-art FEA modeling, the rods are optimized for maximum strength-to-weight ratio, minimizing weak points and ensuring structural integrity under peak loads. Enhanced BushingsHigh-quality precision bushings provide exceptional wear resistance and maintain proper alignment under stress, contributing to long-term reliability. These connecting rods are a must-have upgrade for enthusiasts pushing the limits of their AMG vehicles, offering a perfect balance of performance and durability. Compatible with a range of Mercedes-AMG models, including the C63, E63, GT63, and others, these rods are a key component for achieving peak engine potential.
