Product Details

The COMP Cams 1634-16 Ultra Pro Magnum rocker arm set delivers precision valve train performance for Ford Small Block and 351W engines. These self-aligning rocker arms feature a 1.6:1 ratio to increase valve lift and improve engine breathing without changing camshafts.

Key Features:

  • 1.6:1 rocker ratio for increased valve lift and performance
  • Self-aligning design ensures proper geometry and reduces wear
  • Precision-machined aluminum body for reduced reciprocating weight
  • Roller fulcrum design minimizes friction and wear
  • 3/8" stud mounting for secure, stable installation
  • Engineered specifically for Ford Small Block and 351W applications
  • Complete set for full engine valve train upgrade

The Ultra Pro Magnum series combines lightweight aluminum construction with hardened steel contact points for durability. The self-aligning feature compensates for minor stud misalignment and maintains consistent geometry throughout the valve lift cycle, extending component life and ensuring reliable performance. Ideal for street performance, bracket racing, and mild competition applications.
