Product Details

The COMP Cams 4840-1 guide plates are precision-engineered flat, one-piece guide plates designed specifically for GM LS3 engines. These guide plates provide accurate valve train geometry and pushrod alignment, ensuring optimal valvetrain performance and reliability.

Key Features:

  • Designed for GM LS3 engine applications
  • Compatible with 5/16" diameter pushrods
  • Fits 8mm rocker arm studs
  • Flat, one-piece construction for consistent alignment
  • Precision-machined to maintain proper pushrod angle
  • Helps prevent pushrod deflection under high-stress conditions
  • Essential component for performance valve train setups

Guide plates are critical for maintaining proper pushrod-to-rocker arm alignment, especially in performance applications where increased spring pressures and higher RPM operation can cause pushrod deflection. The COMP Cams 4840-1 guide plates ensure your valve train operates efficiently while reducing wear on pushrods, rocker arms, and valve tips.
