What material are these pushrods made from?

These pushrods are constructed from 4130 Chrome Moly steel, a strong and durable material commonly used in high-stress engine components. They are also heat treated for further strength enhancement.

What does the 'swedged end' mean for these pushrods?

A swedged end is a manufacturing process where the metal is compressed and shaped to create a stronger, reinforced end. This design helps prevent failure under the high forces experienced in the valvetrain.

Are these pushrods sold individually or as a set?

This part number, 25171-8, is for a set of eight pushrods. This is typically enough for a standard 4-cylinder or V-engine configuration.

About this part

Product Details

Manley Performance push rods are a solid option when you're rebuilding or upgrading your engine's valvetrain. This set is designed for applications needing a 7/16 inch diameter pushrod that measures 9.650 inches in length, featuring a 0.165 inch wall thickness. They are constructed from 4130 Chrome Moly steel, a material known for its strength and durability under the stresses of engine operation.

These pushrods are meticulously formed with exact radii on the ends, which helps ensure proper contact with the rocker arms and lifters. You can expect excellent concentricity and closely controlled lengths from this set, critical for consistent valve timing and operation. They are heat treated for added strength and finished with a black oxide coating to help protect against corrosion. The swedged end design adds further reinforcement where it's needed most.
