The proper pushrod length ensures that you can obtain maximum lift from your camshaft and have the most stable valve train for high RPM operation. If you are unsure about what pushrod length you need, use our length-checking-pushrod tools (Contact us for details). Remember, just because your rocker arms may have an adjusting screw it does not mean the screw is there to make up for a pushrod that is too long or short. The adjusting screw is only to set lifter preload or valve lash.
