What material are these push rods made from?

These Manley push rods are constructed from 4130 chrome moly tubing. This material is chosen for its strength and durability in engine applications.

What does 'swedged end' mean for these push rods?

A swedged end means the tube is formed and thickened at the end, allowing for precise machining of the radii. This ensures a solid contact point with the lifter and rocker arm, contributing to accurate valve train operation.

Why is push rod length important?

Correct push rod length is essential for establishing proper rocker arm geometry. Using the wrong length can affect valve lift, valve timing, and potentially lead to premature wear on valve train components.

About this part

Product Details

These Manley push rods are made from 4130 chrome moly tubing with a 0.135-inch wall thickness, measuring 3/8-inch in diameter and 9.450 inches long. The swedged ends are meticulously formed with exact radii, ensuring they seat properly against the lifters and rocker arms. This attention to detail in the end forming is crucial for consistent valve train geometry and performance.

The construction focuses on excellent concentricity and closely controlled length, which are vital for maintaining accurate valve lift and timing. Heat treatment and a black oxide finish add durability and corrosion resistance, making these push rods a solid option for engine builds where reliability is key. They are designed to handle the stresses of regular engine operation.

This set includes eight push rods, enough for a standard V8 engine. Proper push rod length is critical for correct rocker arm geometry, so always double-check your specific engine's requirements before installation.
