What is the primary benefit of using roller rocker arms like these?

Roller rocker arms reduce friction in the valve train compared to standard stamped steel rockers. This can lead to improved engine performance and a more stable valve train operation, especially at higher RPMs.

What is the maximum spring pressure these rocker arms can handle?

These Ultra Pro Magnum rocker arms are designed for use with up to 850 lbs of open spring pressure. It's important to ensure your valve springs do not exceed this rating to maintain the integrity of the rocker arms.

Do these rocker arms come with all the necessary hardware for installation?

This set includes the rocker arms themselves. It is recommended to consult the manufacturer's installation instructions to confirm if any additional hardware, such as guide plates or polylocks, is required for your specific application.
