Product Details

The COMP Cams 855-1 High Energy hydraulic flat tappet lifter set is engineered specifically for International Harvester 266-392 cubic inch engines. These performance lifters feature COMP Cams' High Energy design, which provides improved valve control and durability over stock lifters while maintaining hydraulic operation for quiet, maintenance-free performance.

Key Features:

  • Hydraulic flat tappet design for zero-lash operation and quiet performance
  • High Energy construction with precision-ground surfaces for enhanced durability
  • Premium internal components resist pump-up at higher RPM
  • Direct replacement for International Harvester 266, 304, 345, and 392 engines
  • Compatible with stock or performance camshafts with hydraulic flat tappet profiles
  • Manufactured to strict tolerances for consistent valve train operation

These lifters are ideal for street performance and mild performance builds where hydraulic operation is desired. The High Energy series offers a significant upgrade over worn factory lifters, restoring proper valve train function and improving engine responsiveness. Sold as a complete set for one engine.
