What is the main benefit of using roller rocker arms over stock ones?

Roller rocker arms, like these from COMP Cams, feature a roller tip and needle bearing fulcrum. This design significantly reduces friction compared to the sliding action of stock rocker arms, which can help lower oil temperatures and improve engine response.

Product Details

This set includes sixteen die cast aluminum roller rocker arms, designed to replace the stock rocker arms in a variety of AMC, Ford, and Oldsmobile V8 engines. They feature a 1.6 ratio and a 7/16" stud diameter, making them a solid option for street use and moderate racing applications. These rockers are self-aligning and utilize snap rings to secure the trunnion and bearings.

Crafted from aluminum, these rocker arms offer a strong yet lightweight alternative to heavier factory parts. The needle bearing fulcrum and roller tip work together to significantly reduce friction compared to standard sliding rocker arms. This reduction in friction not only helps lower oil temperatures, which can improve engine response, but also allows for a slight increase in valve lift, contributing to better overall performance. They are built to withstand up to 550 lbs of open spring pressure, offering durability for performance builds.

These rocker arms are a cost-effective way to gain a bit more performance from your engine. They are designed to fit AMC V8s from 290 to 401 cubic inches, Ford V8s from 289 to 351 Windsor, and Oldsmobile V8s from 260 to 455 cubic inches, provided they use a 7/16" stud.
