Product Description

The Carrillo SCR13034-6 connecting rod set is engineered for the BMW B58 family of 3.0L inline-six engines - including its use in the Toyota Supra A90. Built from high-grade chrome-moly steel with a Pro-H beam profile, these rods are designed to deliver exceptional strength, low mass, and high RPM durability. The 3/8" CARR bolt configuration enhances clamp load and fatigue resistance, making this set ideal for high-boost or performance-tuned builds.

Each rod is precision machined and shot-peened, then balanced as a set to ensure uniform performance across all six cylinders. With its 148 mm length, this rod set is tailored specifically for B58 applications. Whether you're building a high-power street car or a race engine, these rods provide a robust foundation for engine reliability and longevity.

Installation should be performed by a skilled engine builder who can check bearing clearances and torque the CARR bolts properly (following stretch or torque-angle procedures). With proper installation and maintenance, the SCR13034-6 connecting rods can significantly upgrade the bottom end strength of any B58-powered build.
