Product Details

The COMP Cams 1621-16 Ultra Pro Magnum rocker arm kit delivers precision valve train performance for Chrysler 383-440 B/RB big block engines. This shaft-mounted rocker system features a 1.5:1 rocker ratio designed to provide reliable valve actuation in street and performance applications.

Key Features:

  • 1.5:1 ratio rocker arms for accurate valve lift and timing
  • Shaft-mount design provides superior stability and reduced flex compared to stud-mount systems
  • Ultra Pro Magnum construction with heat-treated steel components for durability
  • Engineered specifically for Chrysler 383-440 cubic inch B and RB big block engines
  • Complete kit includes rocker arms, shafts, and mounting hardware
  • Precision-machined bearing surfaces minimize friction and wear
  • Roller tip design reduces valve stem wear and side loading

This rocker arm kit is ideal for engine builders and enthusiasts seeking to upgrade or replace worn factory rocker components. The shaft-mount configuration ensures consistent geometry throughout the valve lift cycle, making it suitable for moderate lift camshafts and performance street applications.
