Product Details

The COMP Cams 1431-16 Magnum Roller Rocker Arm Set delivers enhanced performance and durability for Ford small block 289-351W engines equipped with 3/8" rocker studs. Featuring a 1.6:1 rocker ratio, this set increases valve lift compared to stock 1.5 ratio rockers, improving airflow and performance without changing camshafts.

Key Features:

  • 1.6:1 rocker ratio increases valve lift by approximately 7% over stock rockers
  • Roller fulcrum design reduces friction and wear for improved efficiency
  • Precision-manufactured from high-strength materials for reliable operation
  • Fits Ford 289, 302, and 351 Windsor engines with 3/8" rocker studs
  • Complete 16-piece set for V8 application (intake and exhaust)
  • Direct bolt-on installation with compatible valve train components

These Magnum roller rocker arms are an excellent upgrade for street performance and mild racing applications, offering improved valve control and reduced friction compared to stamped steel rockers. The roller fulcrum trunnion design minimizes side loading and extends component life while maximizing power gains throughout the RPM range.
