Product Details

The COMP Cams Ultra Pro Magnum Rocker Arm Set delivers precision-engineered valve train performance for Chevrolet 348 and 409 cubic inch engines. Featuring a 1.7:1 rocker ratio, this set provides increased valve lift compared to stock rockers, optimizing airflow and enhancing engine performance.

Key Features:

  • 1.7:1 rocker ratio for increased valve lift and improved engine breathing
  • Designed specifically for Chevrolet 348-409 cubic inch W-series engines
  • Engineered for 3/8" rocker studs for proper installation
  • Ultra Pro Magnum construction for durability and precision geometry
  • Roller tip design reduces friction and wear on valve stems
  • Complete set for full engine valve train upgrade

This rocker arm set is an excellent choice for performance enthusiasts looking to maximize the potential of their classic big-block Chevrolet W-series engine. The increased rocker ratio works effectively with performance camshafts to enhance horsepower and torque throughout the RPM range.
