Bluesky MISC PPS-591800 Small Block Chevy Pushrod Guide Plate

The Bluesky MISC PPS-591800 is a pushrod guide plate designed for Small Block Chevy (SBC) engines. Guide plates are a critical valvetrain component that locate and stabilize pushrods, maintaining proper alignment between the pushrod, rocker arm, and valve tip throughout the full range of engine RPM.

SBC pushrod guide plates are required when screw-in rocker arm studs are used in place of the factory pressed-in studs — a common upgrade on performance and high-lift camshaft builds. By keeping each pushrod precisely centered in its guide slot, the plates reduce lateral deflection, minimize side loading on valve stems, and help ensure consistent rocker arm geometry.

Key Features:

• Designed for Small Block Chevy (SBC) engine applications
• Stabilizes pushrods for accurate valvetrain alignment
• Compatible with screw-in rocker arm stud conversions
• Helps reduce pushrod flex and side loading on valve stems
• Supports consistent rocker arm geometry across the RPM range
• Part Number: PPS-591800

Proper pushrod guide plate installation requires screw-in rocker arm studs and may require cylinder head machining. Always verify pushrod diameter compatibility (typically 5/16" or 3/8" for SBC applications) before installation.
