Product Details

The COMP Cams Ultra Pro Magnum rocker arm set delivers high-performance valve train control for Chevrolet V6 engines equipped with 7/16" studs. Engineered with a 1.52:1 rocker ratio, this complete set provides increased valve lift compared to stock rockers, enhancing airflow and power output across the RPM range.

Key Features:

  • 1.52:1 rocker ratio for improved valve lift and engine performance
  • Ultra Pro Magnum design with full roller bearing construction for reduced friction
  • Precision CNC-machined aluminum bodies for strength and light weight
  • Self-aligning roller tip design minimizes valve stem wear
  • Designed for Chevrolet V6 engines with 7/16" rocker studs
  • Complete set includes all rockers needed for V6 application
  • Chromoly steel trunnions and high-quality needle bearings for durability

COMP Cams Ultra Pro Magnum rockers are ideal for street/strip applications and mild to moderate performance builds where reliability and consistent performance are essential. The roller bearing design reduces valve train friction compared to bushing-style rockers, freeing up horsepower while extending component life. Compatible with both hydraulic and mechanical camshafts.
