Guide Plate - SBC 5/16 - Flat

The DART Guide Plate - SBC 5/16 - Flat is a precision Small Block Chevy pushrod guide plate engineered for marine engines that demand reliable valve train stability under demanding operating conditions. This 5/16-inch flat guide plate is a critical component in high-performance marine powerplants, where consistent pushrod alignment directly impacts engine longevity and fuel efficiency on the water.

Constructed from steel and finished in black oxide, this guide plate measures 1.8 x 0.2 x 2.85 inches and weighs just 0.09 pounds, making it a compact yet essential valve train component. The flat design provides proper guidance for 5/16-inch pushrods, controlling lateral movement and ensuring that rocker arm geometry remains correct throughout the engine's RPM range. Black oxide finish resists corrosion from the salt air and moisture common in marine environments, protecting against deterioration that can compromise engine reliability over extended seasons.

This component is ideal for boaters rebuilding or maintaining Small Block Chevy marine engines, whether for inboard applications, bass boat power plants, or offshore fishing vessels where engine dependability is non-negotiable. Marine mechanics and engine builders rely on quality guide plates to prevent pushrod wear, maintain proper valve timing stability, and avoid the costly downtime that comes from valve train misalignment at sea.

OEM replacement quality and precise fit make the DART guide plate a trusted choice for complete engine rebuilds and restoration projects. Each plate is manufactured to exact Small Block Chevy specifications, ensuring hassle-free installation and reliable performance across the full operating envelope of marine powerplants.
