Product Details

The COMP Cams 7643-1 Magnum pushrod is a precision-engineered valve train component designed for high-performance and racing applications. This pushrod features a 7.700-inch length, making it suitable for engines with specific deck heights and rocker arm geometries.

Key Specifications:

  • Length: 7.700 inches
  • Wall Thickness: .080 inches for excellent strength-to-weight ratio
  • Diameter: 5/16 inch (7.94mm)
  • Material: Seamless chromoly steel construction
  • Heat-treated for maximum durability and resistance to deflection

Features and Benefits:

  • Magnum series design provides superior rigidity and stability at high RPM
  • Thicker .080-inch wall thickness reduces flex under high valve spring pressures
  • Precision-manufactured with tight tolerances for consistent valve train geometry
  • Ball/ball ends are CNC-machined for optimal contact with rocker arms and lifters
  • Ideal for performance street engines, bracket racing, and aggressive camshaft profiles

COMP Cams Magnum pushrods are designed to eliminate valve train flex and maintain proper geometry throughout the RPM range, ensuring reliable performance and preventing costly engine damage from pushrod failure.
