5/16 Hi-Energy Pushrods - 9.146 Long

The COMP Cams 5/16 Hi-Energy Pushrods - 9.146 Long (set of 16) deliver precision valve train control for Pontiac V8 engines demanding reliable high-RPM performance. These solid steel pushrods are engineered to withstand aggressive cam profiles and maintain consistent geometry under extreme conditions, making them essential for serious engine builds where valvetrain stability directly impacts horsepower delivery and engine longevity.

At 9.146 inches in length with a 5/16-inch outer diameter, these pushrods are sized specifically for compatible Pontiac V8 applications. The steel construction provides the rigidity necessary to transmit cam lobe action to rocker arms without flex or deflection—critical when running elevated valve spring pressures typical of performance and racing engines. COMP Cams' Hi-Energy designation indicates pushrods optimized for high-lift, aggressive valve events where standard components would compromise reliability and consistency. The complete set of 16 ensures matched geometry across all cylinders, eliminating any variables that could cause uneven valve timing or mechanical failure.

Whether you're building a street performance engine, preparing for weekend racing, or restoring a classic Pontiac V8 with modern cam technology, these pushrods provide the durability and precision required for dependable operation. The set format eliminates the frustration of sourcing individual components and ensures complete compatibility across the entire valvetrain. Buyers upgrading from factory or worn pushrods will see improved valve response, reduced noise, and enhanced engine stability at higher RPM ranges where inferior components fail.
