COMP Cams 8417-1 Hi-Tech Pushrod Length Diameter Wall Engine Push Rod - 8.100 5/16 105

The COMP Cams 8417-1 Hi-Tech pushrod is precision-engineered for high-performance engine applications requiring exact valve train geometry. This pushrod features an 8.100-inch length, making it ideal for specific engine builds where precise pushrod length is critical for proper rocker arm geometry and valve timing.

Key Specifications:

• Overall length: 8.100 inches
• Diameter: 5/16 inch (.3125")
• Wall thickness: .105 inch for excellent strength-to-weight ratio
• Seamless chromoly steel construction for maximum durability
• Heat-treated for superior strength and rigidity
• Precision ball and cup ends for reliable lifter and rocker arm contact

COMP Cams Hi-Tech pushrods are manufactured to exacting tolerances to ensure consistent valve train operation at high RPM. The .105-inch wall thickness provides the structural rigidity needed to prevent flex under high spring pressures while maintaining a lightweight design. Each pushrod is individually straightness-checked to ensure proper valve train geometry and minimize side loading on valve guides.

These pushrods are designed for use with performance camshafts, upgraded valve springs, and roller rocker arms in racing and high-performance street applications. Proper pushrod length is essential for optimizing rocker arm geometry and maximizing valve lift efficiency.
