Manley 25181-8 4130 Chrome Moly Swedged End Pushrods 7/16" x 11.100" .165 Wall

Engineered for high-performance and racing valvetrain applications, these pushrods deliver the rigidity and dimensional precision required to maintain accurate valve timing under demanding conditions.

Key Features:

• Material: 4130 Chrome Moly steel for exceptional strength-to-weight ratio
• Diameter: 7/16" (0.4375")
• Length: 11.100"
• Wall Thickness: .165" — heavy wall for maximum rigidity and deflection resistance
• Swedged ends with meticulously formed exact radii for smooth rocker arm and lifter contact
• Excellent concentricity and closely controlled length tolerances for consistent valvetrain geometry
• Heat treated and black oxide finished for durability and corrosion resistance

Manley's 4130 Chrome Moly pushrods are purpose-built to resist deflection under high spring loads and extreme RPM conditions, making them an ideal upgrade for performance street, strip, and race engines that demand precision valvetrain components.
