3/8 Hi-Tech Pushrod - 8.550 Long

The 3/8 Hi-Tech Pushrod - 8.550 Long from COMP CAMS is engineered for high-performance marine engines where precise valve actuation and durability under sustained load are non-negotiable. Whether you're rebuilding a freshwater bass boat or restoring a saltwater cruiser, this chromoly pushrod delivers the consistency that serious boaters demand. Pushrods are critical components in your engine's valvetrain; they transfer motion from the camshaft to the rocker arms, and any flex or wear directly impacts timing, efficiency, and reliability on the water.

Constructed from chromoly steel with a 0.080-inch thick wall, the 3/8 Hi-Tech Pushrod resists flex and fatigue under the sustained RPM and thermal cycling typical of marine service. The Hi-Tech designation indicates optimized weight and strength—lighter than solid designs, yet rigid enough to maintain accurate valve timing across the full operating envelope. At 8.550 inches long with a 3/8-inch diameter, this pushrod is dimensionally precise for engines requiring exact valvetrain geometry; any deviation compromises cam timing and can reduce power, increase fuel consumption, or cause mechanical damage. The compact 0.18-pound weight per unit supports lightweight, responsive valve response without sacrificing longevity.

Boaters performing engine overhauls or upgrading to performance cam packages will find this pushrod essential for maintaining factory or aftermarket cam timing precision. If your boat has been running rough, experiencing timing scatter, or losing top-end power, worn or bent pushrods are a common culprit—replacement ensures your valvetrain actuates exactly as designed. Installation requires proper pushrod length verification; the 8.550-inch length is specific to certain engine block and cylinder head combinations, so confirm fitment with your marine engine manual or technician before ordering. Sold individually, so verify your engine's requirement before purchasing the correct quantity for your complete valvetrain rebuild.
