What is the purpose of a pushrod guide plate?

A pushrod guide plate sits between the lifter and the rocker arm, helping to keep the pushrod centered in its bore. This ensures consistent movement and reduces side-loading, which can cause wear on the pushrod and other valve train parts.

What does 'heat-treated' mean for this part?

Heat-treating is a process that changes the metal's internal structure to make it stronger and more resistant to wear. This means the guide plate can handle the stresses of engine operation for longer.

Does this guide plate come with hardware?

This part is sold as a single guide plate. Hardware for installation is not typically included and should be sourced separately if needed.

About this part

Product Details

This is a Manley Steel Guide Plate, specifically made for Big Block Chevy engines that use 3/8 inch pushrods. Its main job is to keep those pushrods properly aligned as they move up and down. Proper alignment is key for the valve train to work smoothly and consistently, ensuring your engine runs as it should.

Manley makes these guide plates from stamped steel, and they've been heat-treated for added strength. A black oxide finish is applied to help resist corrosion. While it might seem like a small part, getting this right helps prevent premature wear on your pushrods and other valve train components.

This guide plate is sold individually. If you're rebuilding or working on the top end of your Big Block Chevy, this is a well-built piece that will do the job.
