What is the benefit of aluminum rocker arms?

Aluminum rocker arms are lighter than their steel counterparts. This reduced weight can help decrease stress on the valvetrain and potentially improve engine responsiveness.

What does the 1.5 ratio mean for my engine?

A 1.5 ratio means that for every amount of lift the camshaft provides, the rocker arm multiplies that lift by 1.5 at the valve. This effectively increases valve lift and duration, which can lead to improved airflow and engine performance.

Do these rocker arms come with installation hardware?

This set includes eight narrow body aluminum rocker arms. It is recommended to consult the manufacturer's installation guide or contact COMP Cams for specific details on included hardware for your application.

Product Details

These COMP Cams Ultra-Gold ARC rocker arms are made from aluminum and feature a narrow body design, which is important for clearing other engine components, especially in tighter engine bays. They come with a 1.5 ratio, meaning the valve lift will be 1.5 times the camshaft lift, helping to increase valve lift and duration for improved engine performance. This set includes eight rocker arms, designed to fit Chevrolet Small Block engines from 1988 and newer that use a 3/8 inch stud.

The aluminum construction makes these rocker arms lighter than steel alternatives, which can help reduce valvetrain stress and improve overall engine responsiveness. The narrow body design is a key feature, allowing for better clearance around valve springs and other parts in the engine, which can simplify installation and prevent interference issues. This particular set is well-suited for a range of vehicles, including many Chevrolet C/K series trucks, Camaros, and Pontiac Firebirds from the late 80s and early 90s, as well as some Buick and GMC models.

When installing these rocker arms, ensure you are working with a 3/8 inch stud size, as specified for this model. Proper installation is key to achieving the performance benefits these COMP Cams rocker arms offer.
