What material are these push rods made from?

These push rods are constructed from 4130 chrome moly, a strong and durable alloy. They also feature a heat-treated and black oxide finish for added resilience and corrosion resistance.

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

A swedged end is a manufacturing process where the end of the tube is compressed and shaped. This creates a stronger, more integrated connection point for the push rod, ensuring a secure fit with the lifter and rocker arm.

Why is concentricity important for push rods?

Excellent concentricity means the push rod is perfectly round and uniform along its length. This ensures consistent contact with the lifter and rocker arm, contributing to precise valvetrain geometry and smoother engine operation.

About this part

Product Details

If you're rebuilding the top end of your engine, getting the valvetrain geometry just right is crucial. These Manley push rods are built to help you achieve that precision. They connect the rocker arms to the lifters, transferring the motion from the camshaft to open and close your engine's valves. Getting this link right ensures your engine breathes properly and performs as it should.

These push rods are made from 4130 chrome moly, a strong and durable material that can handle the stresses of engine operation. The ends are meticulously formed with exact radii, and the overall concentricity is closely controlled. This attention to detail means they fit precisely into their mating components, which is important for consistent valvetrain operation. They're also heat-treated and finished with a black oxide coating for added durability and corrosion resistance.

This set includes 16 push rods, enough for a typical V8 engine. The swedged end design is a common feature that helps ensure a secure fit. When you're putting an engine back together, using well-made components like these Manley push rods can make a noticeable difference in how smoothly everything operates.
