Precision Enduro Rocker Arm for Big Block Chevy

Unlock the full potential of your Big Block Chevy (BBC) with the Crower Cams Enduro series rocker arm. Engineered for power and longevity, this 1.7 ratio rocker arm is the perfect upgrade for high-performance builds. The full roller design ensures that your valvetrain operates with minimal friction, allowing for consistent valve lift and improved engine responsiveness.

Key Specifications and Features

  • Application: Big Block Chevy (BBC)
  • Stud Size: 7/16 inch
  • Ratio: 1.70
  • Material: High-tensile stainless steel
  • Design: Full roller tip and trunnion
  • Series: Enduro

The Enduro series is built to withstand extreme conditions, making it an excellent choice for street/strip and endurance racing applications. The use of stainless steel provides the necessary strength to handle aggressive camshaft profiles and high-pressure valve springs without the deflection common in lower-quality aluminum rockers. By reducing friction at the valve tip, these rockers help preserve your valve guides and ensure that your engine maintains its peak power output for longer periods. Each rocker is precision-machined to ensure that your valve lift remains accurate, providing the performance consistency required for competitive racing. Whether you are tuning for the drag strip or building a high-torque street machine, these rockers provide the reliability you need. Invest in your engine's performance with top-tier components from GGCRACING.
