Product Details

The COMP Cams 1431-1 Magnum Roller Rocker Arm delivers enhanced performance and durability for Ford small block engines. Designed specifically for 289-351W applications, this rocker arm features a 1.6:1 ratio that increases valve lift for improved airflow and power output compared to stock rockers.

Key Features:

  • 1.6:1 rocker ratio increases valve lift and performance
  • Roller tip design reduces friction and valve guide wear
  • Precision needle bearing trunnion for smooth, reliable operation
  • Fits Ford 289, 302, and 351 Windsor engines with 3/8" rocker studs
  • Investment cast chromoly steel body for exceptional strength
  • Sold individually - order quantity needed for your application

This rocker arm is engineered for street and performance applications where increased valve lift and reduced friction are critical. The roller tip minimizes wear on valve stems while the precision needle bearing design ensures consistent geometry throughout the RPM range. Ideal for use with performance camshafts and cylinder head upgrades.
