Airflow Research 6111-8 BBC 3/8" Pushrod Guide Plates 8-Pack

The Airflow Research (AFR) 6111-8 guide plates are precision-manufactured 3/8" pushrod guide plates designed for Big Block Chevy (BBC) cylinder heads. Sold as a complete 8-piece set, these guide plates ensure accurate pushrod alignment with the rocker arm for consistent valve train geometry and reduced wear.

Key Features:

• Designed specifically for Big Block Chevrolet (BBC) applications
• Fits 3/8" diameter pushrods
• 8-piece set — enough for a complete engine (one per cylinder)
• Precision-machined for accurate pushrod-to-rocker alignment
• Helps maintain proper valvetrain geometry under high-performance and racing conditions
• Compatible with AFR BBC cylinder heads and other BBC heads that accept guide plates
• Manufactured to tight tolerances for reliable, repeatable performance

Proper pushrod guide plates are a critical component in any performance valvetrain assembly. By keeping pushrods centered and tracking correctly through the guide, these plates reduce side loading on pushrods and rocker arms, extend component life, and help maintain consistent valve lift across all cylinders. The AFR 6111-8 set is an ideal replacement or upgrade part for street performance and race BBC builds.
