What is the benefit of a 1.6 ratio rocker arm?

A 1.6 ratio rocker arm increases valve lift and duration compared to a stock 1.5 ratio. This allows more air and fuel into the cylinder and more exhaust out, potentially leading to improved engine performance and power.

Does this rocker arm set include pushrods or other hardware?

This product listing is for the Ultra Pro Magnum XD rocker arm set only. It is recommended to check the manufacturer's specifications or consult with a technician to ensure you have the correct length pushrods and any other necessary hardware for installation.

What is the advantage of a roller tip rocker arm?

The roller tip on these rocker arms helps to reduce friction and wear on the valve stem and valve guide. This can lead to a longer lifespan for your valvetrain components and potentially smoother engine operation.

Product Details

COMP Cams is well-known for making performance valvetrain components that help engines breathe better and make more power. This Ultra Pro Magnum XD rocker arm set is a prime example, offering a 1.6 ratio that can improve valve lift and duration without needing to change your camshaft. This is a solid option for anyone looking to get more out of their engine, whether it's a street machine or a weekend racer.

These rocker arms are built from strong, solid steel and feature a roller tip to reduce friction and wear on your valve guides and valve stems. The 7/16-inch stud size is a common fitment for many GM V8 engines, and the 1.6 ratio is a popular choice for a noticeable improvement in performance. They are designed to fit a wide range of vehicles, including popular models like the Chevrolet Camaro, Pontiac Firebird, and Chevrolet Impala, among many others. The roller tip design is particularly helpful in reducing side-loading on the valve guides, which can extend the life of your valvetrain components.

When installing these rocker arms, it's important to ensure you have the correct length pushrods and that your valve springs are up to the task of handling the increased lift. Always refer to the manufacturer's installation instructions for specific details and torque specifications to ensure a proper and reliable setup. This set is designed to be a direct replacement for many GM V8 applications, making it a straightforward upgrade for those looking to enhance their engine's performance.
