5/16 Magnum Pushrod - 7.342 Long

The 5/16 Magnum Pushrod - 7.342 Long by COMP CAMS is a precision valve train component engineered for small block Mopar engines requiring bulletproof reliability on the water. Whether you're running a performance marine engine in a bass boat, center console, or cruiser, a quality pushrod is critical to maintaining consistent valve timing and preventing catastrophic engine failure underway. This magnum-spec rod delivers the strength and dimensional accuracy that serious boaters and engine builders demand when every run across open water matters.

Manufactured from chromoly steel with a 0.080-inch thick wall, the 5/16 Magnum Pushrod handles high-RPM loading and thermal cycling without flex or failure. At 7.342 inches in length and 5/16-inch diameter, this pushrod is purpose-built for small block Mopar applications where clearance and transfer geometry demand precision engineering. The chromoly construction resists fatigue cracking far better than standard steel, a critical advantage in marine engines subjected to sustained high-RPM operations and constant acceleration cycles. Each rod is individually crafted to ensure concentricity and uniform wall thickness—factors that directly impact valve sealing and engine efficiency.

Boaters rebuilding carbureted or fuel-injected small block Mopar engines will benefit most from the durability and dimensional consistency of this COMP CAMS pushrod, particularly those pushing higher RPMs for tournament fishing or performance cruising. Installation requires proper length verification against your specific cylinder head and block configuration; always measure your existing pushrod or consult your engine builder before ordering. The 0.12-pound weight per rod is typical for this application, and replacement sets should be installed whenever performing major valve train work or addressing valve train noise. For reliability that won't let you down on the water, the 5/16 Magnum Pushrod is the specification choice.
