Manley 25366-8 4130 Chromoly Pushrods 3/8" Diameter 9.350" Length .135" Wall Set of 8

The Manley 25366-8 is a premium set of eight heavy-wall pushrods engineered for high-performance and racing applications. Constructed from heat-treated 4130 chromoly steel, these pushrods deliver exceptional strength and durability for engines running high spring pressures, aggressive cam profiles, or power adders like nitrous and forced induction.

Key Specifications:

• Length: 9.350 inches
• Diameter: 3/8 inch (0.375")
• Wall Thickness: .135 inch (heavy-wall construction)
• Material: Heat-treated 4130 chromoly steel
• End Style: Swedged ends with meticulously formed radii
• Finish: Black oxide coating for reduced wear and corrosion resistance
• Quantity: Set of 8 pushrods

Performance Features:

• Heavy .135" wall thickness provides superior strength and rigidity for high-load applications
• Precision-manufactured for excellent concentricity and closely controlled length tolerances
• Swedged ends feature exact radii for proper rocker arm and lifter contact
• Black oxide finish reduces friction and extends component life
• One-piece construction eliminates weak points found in two-piece designs

Manley's 4130 chromoly pushrods are ideal for street performance, circle track racing, drag racing, and other demanding applications where valvetrain stability is critical. The heavy-wall design resists flexing under high RPM and extreme valve spring pressures, ensuring consistent valvetrain geometry and reliable engine performance. As with all pushrods, proper length measurement is essential to achieve correct valvetrain geometry for your specific engine combination.
