Product Details

Designed for blocks originally equipped with a factory hydraulic roller cam ('87 and later), these lifters drop in without modification and retain compatibility with OEM lifter guides and retainers.

Compared to flat tappet lifters, these OE-style hydraulic roller lifters deliver reduced valvetrain friction and improved longevity, while also supporting significantly more aggressive camshaft profiles — making them an ideal upgrade for performance builds alongside COMP Cams' High Energy hydraulic roller cam series.

Key Features:

  • OE-Style, No Link Bar design for simplified installation and OEM guide/retainer compatibility
  • 0.842" diameter — correct fit for '87+ Chevy Small Block (SBC), Gen II LT1, and LS-series engine families
  • 2.66" seat height for proper valvetrain geometry
  • 122g per lifter — lightweight construction to support higher engine speeds
  • Decreased friction and increased longevity versus flat tappet lifters
  • Compatible with more aggressive cam profiles than flat tappet lifters allow

The 850-4 is the ideal solution for partial replacements, cylinder-specific repairs, or builds requiring individual lifter quantities. For full engine sets, COMP Cams also offers the 850-16 (16-piece set).
