Product Details

The COMP Cams 4839-1 flat adjustable guide plates provide precise pushrod alignment for Small Block Chevy and Ford 289-351W engines. These two-piece guide plates allow fine-tuning of pushrod geometry to optimize valve train performance and reduce wear.

Key Features:

  • Designed for 3/8" diameter pushrods and 7/16" rocker studs
  • Two-piece adjustable design allows precise pushrod alignment adjustment
  • Flat profile design for proper clearance in most applications
  • Manufactured from high-quality steel for durability
  • Compatible with Small Block Chevy and Ford 289, 302, and 351W engines
  • Helps correct pushrod-to-guide interference and optimize valve train geometry
  • Sold as a pair for one rocker arm position

Guide plates are essential for controlling pushrod location and ensuring proper valve train operation, especially in high-performance applications. The adjustable design of these COMP Cams guide plates makes them ideal for engines with non-standard deck heights, head milling, or aftermarket cylinder heads where pushrod alignment may need correction.
