5150 AutoSport Pro-Xtreme Connecting Rods, manufactured by CP-Carrillo, are designed to handle extreme horsepower and high RPM applications for BMW S58 engines, as found in the G80 M3, G81 M3, G82 M4, G83 M4, G87 M2, F97 X3M, and F98 X4M. Constructed from high-strength aircraft-grade steel, these connecting rods are engineered to withstand the forces generated by high-performance engines. Unique to 5150, these Connecting Rods were also designed with optional tapered small end to ensure compatibility with factory OEM pistons. Tapered Rods are compatible with factory pistons while Non-Tapered Rods required aftermarket pistons. See photos for details. The Pro-Xtreme design is specifically engineered to handle up to 2000 horsepower, making them suitable for high-performance turbo/drag racing or street/strip applications. They are also designed to handle high engine speeds of up to 9500 RPM, which is necessary for achieving maximum power output. Each connecting rod is precisely engineered to meet the demands of high-performance engines using advanced manufacturing techniques such as computer-aided design (CAD) and finite element analysis (FEA). The Pro-Xtreme Connecting Rods are designed to be durable, reliable, and capable of handling the extreme stresses and forces generated by high-horsepower and high-rpm engines.
