COMP Cams 42140509901 Hi-Tech Chromoly Pushrod 5/16 in. Diameter 9.900 in. Length

The COMP Cams 42140509901 is a Hi-Tech series performance pushrod engineered for demanding street performance and race engine applications. Built from seamless chromoly tubing with a 0.080-inch wall thickness, this pushrod delivers the rigidity and durability required to maintain consistent valve train geometry under high-rpm and high spring-pressure conditions.

COMP Cams engineers recognized that pushrod frequency must be matched to the rest of the valve train components and the engine's operating RPM range — not simply built strong enough to avoid failure. The Hi-Tech series is the result of that engineering discipline.

Key Features:

• Series: Hi-Tech — designed for hardcore street performance and race applications
• Diameter: 5/16 inch (0.3125 in.)
• Length: 9.900 inches
• Wall Thickness: 0.080 inch seamless chromoly tubing
• One-piece construction for maximum strength and consistency
• Precision-formed ends with added thickness in the critical tip area for durability
• Heat-treated for compatibility with guide plates and maximum strength
• OD-ground for dimensional consistency
• Black oxide finish with length and part number laser etched on OD for easy identification

These pushrods are ideal for builds where aggressive cam profiles and elevated valve spring pressures demand a stronger, more precisely matched valve train component. Sold individually — verify correct pushrod length using a COMP Cams pushrod length checker prior to final installation.
