3/8 Hi-Tech Pushrod - 8.150 Long

The 3/8 Hi-Tech Pushrod - 8.150 Long from COMP CAMS is engineered for serious engine builders and performance mechanics who demand precision valve train geometry. This pushrod serves as the critical link between your rocker arm and lifter, directly controlling valve lift and timing accuracy in small-block and mid-block applications. Whether you're building a street cruiser, weekend racer, or high-revving competition engine, selecting the correct pushrod length and diameter is fundamental to maximizing valve event consistency and preventing valve train geometry errors that compromise performance.

COMP CAMS' Hi-Tech pushrod construction combines lightweight design with rigidity to minimize flex under high-lift, high-RPM operation. The 3/8-inch diameter offers the optimal balance between strength and reduced reciprocating mass, allowing faster acceleration and deceleration of valve train components during aggressive valve events. At 8.150 inches in length, this pushrod is sized for specific small-block applications where proper installed height and rocker arm geometry are critical—using an incorrect length introduces binding, excessive side load on rocker studs, and premature wear. The manufacturing tolerances ensure consistent, repeatable performance across multiple assemblies.

Experienced engine builders and performance shops rely on COMP CAMS pushrods when blueprinting Chevy small-blocks and comparable platforms requiring tight valve train control. Before installation, verify your specific engine block, cylinder head combination, and rocker arm type to confirm the 8.150-inch length matches your required pushrod geometry—incorrect length is one of the most common causes of valve train failure in modified engines. This pushrod pairs seamlessly with COMP CAMS' full range of rocker arms, lifters, and camshafts, making it an essential component for any serious engine refresh or complete racing build.
