5/16 Hi-Tech Pushrods - 8.800 Long

The COMP CAMS 5/16 Hi-Tech Pushrods - 8.800 Long represent a precision-engineered solution for serious engine builders and high-performance machine shops. Pushrods transmit valve actuation commands from the camshaft to rocker arms in overhead-valve (OHV) and pushrod-based engine architectures, making them critical to camshaft timing accuracy and valve train reliability. These chromoly construction pushrods deliver the rigidity and repeatability required when upgrading to aggressive cam profiles, larger valve lifts, or increased RPM capability where factory pushrods cannot safely handle the mechanical stress.

Built from chromoly steel with a 0.080-inch thick wall and 5/16-inch diameter, these Hi-Tech pushrods provide superior strength-to-weight ratio compared to standard steel or cast iron designs. The 8.800-inch length is engineered for correct installed geometry, ensuring proper rocker-arm geometry, valve lash clearance, and elimination of bind during the full lift cycle. The heavier wall construction resists column buckling and flexing under valve train loads, which translates to consistent valve timing across the entire RPM range—critical for power output consistency and preventing valve float at high speeds. This set of 16 units covers a full V8 engine, simplifying ordering and ensuring matched performance across all cylinders.

Mechanics and engine builders upgrading to Comp Cams aftermarket camshaft packages routinely specify Hi-Tech pushrods to ensure the valve train can sustain aggressive lift and duration without mechanical failure. These are essential for small-block Chevrolet, Ford, Mopar, and other OHV platforms where performance modifications demand superior valve train component quality. Installation requires proper pushrod length measurement to achieve correct preload on hydraulic lifters or solid lifter buckets; incorrect length leads to valve lash issues or loss of rocker-arm contact. Always verify fitment with your specific engine block, head, and rocker-arm combination before final assembly.
