Product Details

The COMP Cams 1477-16 rocker arm set delivers high-performance valve train operation for GM LS1 engines with a precision-engineered 1.7:1 ratio design. These rocker arms feature upgraded trunnion bearings that eliminate the weak needle bearing design found in many stock LS applications, providing superior durability and reliability under high-performance conditions.

Key Features:

  • 1.7:1 rocker ratio increases valve lift for improved airflow and performance
  • Upgraded trunnion bearing design eliminates premature needle bearing failure
  • High-strength steel construction with precision CNC-machined surfaces
  • Direct bolt-on replacement for GM LS1 engines
  • Complete set includes all rocker arms needed for engine rebuild or upgrade
  • Enhanced oiling system ensures proper lubrication under demanding conditions

This rocker arm set is engineered for enthusiasts seeking reliable performance upgrades and engine builders looking to eliminate common LS valve train weaknesses. The increased ratio works with your existing camshaft to maximize lift while the trunnion upgrade provides the durability needed for high-RPM operation and extended service life.
