About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these push rods are a great example of that. If you're rebuilding your top end or looking for a solid replacement for your engine, these push rods are built to handle the job. They're made from 4130 chrome moly, a material chosen for its good strength and durability under the stresses of engine operation.

What sets these apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, which helps ensure they seat properly against your lifters and rocker arms. You also get excellent concentricity and closely controlled lengths, meaning each push rod in the set is very similar to the others. This consistency is important for proper valve train geometry and smooth operation. They're heat treated and finished with a black oxide coating, which adds a layer of protection and helps them resist corrosion.
