What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing, which is known for its strength and durability in high-stress applications like an engine's valve train.

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

A swedged end means the tubing has been formed and reinforced at the end, creating a stronger connection point. For these push rods, the ends are meticulously formed with exact radii to ensure they seat properly in the rocker arms and lifters.

Are these push rods a direct replacement for all engines?

These push rods have specific dimensions (3/8" diameter, 6.950" length, 0.080" wall). You'll need to verify these measurements match the requirements for your specific engine build to ensure proper fitment and valve train geometry.

About this part

Product Details

These Manley push rods start with a 0.080 inch wall thickness, built from strong 4130 chrome moly tubing. This material choice means they can handle the stresses of an engine working hard, and the swedged ends are formed with exact radii, which helps them seat properly in the rocker arms and lifters. This attention to detail in forming the ends, along with excellent concentricity and closely controlled lengths, ensures they function as a matched set. They’re also heat-treated and finished with a black oxide coating to help resist corrosion and wear.

When you're rebuilding the top end of your engine, getting the push rod length and strength right is crucial for proper valve train geometry and consistent performance. Manley has been making performance engine components for a long time, and these push rods reflect that experience. They fit right and are built to last, making them a solid option for your build.
