3/8in Adj. Guide Plates

The ISKY CAMS 3/8in Adjustable Guide Plates (Part Number 300AGP) are precision-engineered pushrod guide plates designed for small block Chevy engines. Built from steel with a black oxide finish, this set of eight flat-design guide plates manages pushrod deflection and maintains valve train geometry under high-RPM operation. Adjustable construction allows tuners to fine-tune clearance and eliminate lateral rod movement that can compromise cam profile accuracy and reduce valvetrain reliability.

These 3/8-inch guide plates fit standard small block Chevy pushrod assemblies and accommodate the 0.93 lb total weight of eight units across your engine's valve train. The flat profile and adjustable design eliminate the binding that can occur with fixed guides, reducing friction losses and extending pushrod life. Black oxide coating resists corrosion and blends seamlessly with factory-style engine finishing. The 5.5 x 0.65 x 8.55-inch dimensions per unit confirm fit within standard small block Chevy architecture.

Serious engine builders and high-performance small block Chevy enthusiasts rely on adjustable guide plates to maintain tight valve train tolerances during peak power delivery. Whether you're building a street performance engine, bracket racing platform, or marine application, controlling pushrod deflection is critical to cam lobe preservation and consistent valve timing. These ISKY CAMS components deliver the precision adjustment necessary for custom cam installations and forced-induction builds where aggressive valve events push standard fixed guides to their limits.
