Product Details

The COMP Cams 1211-1 High Energy rocker arm is engineered to deliver reliable performance for Chevrolet big block engines equipped with 7/16" studs. Featuring a 1.7:1 rocker ratio, this rocker arm increases valve lift compared to stock 1.5:1 rockers, providing improved airflow and power potential without changing the camshaft.

Key Features:

  • 1.7:1 rocker ratio for increased valve lift and performance
  • Designed specifically for Chevrolet big block engines
  • Fits 7/16" rocker studs (standard on most big block Chevy applications)
  • High Energy series construction for durability and performance
  • Direct replacement for stock rocker arms
  • Steel construction with precision machined components

This rocker arm is ideal for street performance and mild race applications where increased valve lift is desired. The 1.7 ratio provides approximately 13% more lift than stock rockers, improving engine breathing and power output. Compatible with most aftermarket valve spring pressures found in street/strip combinations.
