What is the purpose of pushrods in an engine?

Pushrods are part of the valvetrain system. They transfer the lifting motion from the lifters to the rocker arms, which then open and close the engine's intake and exhaust valves. Proper pushrod length and diameter are crucial for correct valve timing and lift.

What does 'chromoly' steel mean for these pushrods?

Chromoly steel, which is short for chromium-molybdenum steel, is a type of alloy steel known for its strength and toughness. Using chromoly makes these pushrods well-built and able to withstand the stresses of engine operation.

What is the benefit of the black oxide finish?

The black oxide finish on these pushrods serves a couple of purposes. It helps to prevent rust and corrosion, keeping the parts in good condition. It also contributes to a more uniform surface that can aid in lubrication and reduce friction within the valvetrain.

About this part

Product Details

In this set, you get eight Manley 7.875-inch long, 3/8-inch diameter pushrods made from chromoly steel. These pushrods are a key component in your engine's valvetrain, transferring the motion from the lifters to the rocker arms, which in turn open and close the valves. Getting this part right is important for proper engine timing and performance.

Manley has paid close attention to the details with these pushrods. The ends are meticulously formed with exact radii, and they maintain excellent concentricity, meaning they are perfectly centered. This precise construction, along with closely controlled lengths, helps ensure smooth operation and consistent valve lift. They've also been heat treated and finished with a black oxide coating, which adds to their durability and helps prevent corrosion.
