Carrillo 3/8in CARR Connecting Rod Bolts

The Carrillo Pro-Series 3/8 CARR Fasteners (BLT-CARR6-PS) are engineered to meet the increasing load demands of modern high-performance engines. Designed as an upgrade from Carrillo’s standard 3/8 CARR bolts, these Pro-Series fasteners feature a thicker shank and require more stretch to achieve optimal clamp load, ensuring superior strength and durability in extreme applications.

These bolts are ideal for BMW race engines and high-horsepower builds, where higher clamp loads are essential to prevent rod cap movement under stress. Perfect for forced induction, high-RPM, and endurance racing environments, the Pro-Series 3/8 CARR bolts provide greater structural integrity than their predecessors, making them the new standard in CP-Carrillo fasteners.

Proper installation is crucial, as these bolts require precise stretch specifications to maximize performance. Always refer to the included instructions and check the head markings to verify the correct fastener type.

Key Features:

• Thicker shank design for enhanced strength and load capacity
• Replaces standard 3/8 CARR fasteners for improved performance and reliability
• Optimized clamp load prevents rod cap shift under extreme conditions
• Ideal for BMW engines used in racing, forced induction, and high-RPM applications
• Requires 0.0065-0.0075" stretch during installation for peak performance
