Product Details

The COMP Cams Ultra Pro Magnum XD rocker arm delivers professional-grade valvetrain performance for Chevrolet big block engines. Engineered with a 1.73:1 rocker ratio, this rocker arm increases valve lift and duration compared to stock components, maximizing airflow potential for improved horsepower and torque output.

Key Features:

  • 1.73:1 rocker ratio for increased valve lift and performance
  • Ultra Pro Magnum XD construction for enhanced strength and durability
  • Designed for Chevrolet big block engines with 7/16" rocker studs
  • Precision needle bearing design reduces friction and wear
  • CNC-machined aluminum body provides excellent strength-to-weight ratio
  • Self-aligning design ensures proper valve stem contact
  • Compatible with high-lift camshafts and high-RPM applications

This rocker arm is ideal for performance builds, racing applications, and street/strip combinations where increased valve lift and reduced valvetrain friction are critical. The Ultra Pro Magnum XD series represents COMP Cams' commitment to precision manufacturing and race-proven reliability.
