What is the primary benefit of using roller rocker arms?

Roller rocker arms, like these from Edelbrock, reduce friction in the valvetrain compared to traditional stamped steel rockers. This can lead to improved performance and potentially longer component life.

What size valve springs can these rocker arms accommodate?

The full body design of these Edelbrock rocker arms is made to clear valve springs up to 1.65 inches in diameter, offering good compatibility with various performance spring setups.

Are any special tools required for installation?

Installation typically involves standard engine hand tools for removing and replacing valve covers and rocker arms. It's always recommended to refer to the manufacturer's installation instructions for specific details and torque specifications.

Product Details

If you're working on the top end of your Small-Block Ford, like a 289 or 351 Windsor, these Edelbrock Red Roller Rocker Arms are a solid choice for improving valve lift and operation. This set includes 16 rockers, featuring a 1.6:1 ratio, designed to work with 3/8 inch studs. They're made right here in the USA from lightweight 7129 grade aluminum, which helps reduce valvetrain stress.

Edelbrock machines the body of these rockers using CNC equipment for accuracy, then micro polishes and anodizes them to help them hold up over time. The internal components, like the trunnion race, roller pin, and roller tip, are centerless ground for a smooth finish and consistent performance. You'll find a high-quality Torrington needle bearing fulcrum supporting the roller tip, ensuring smooth operation and reduced friction as the valve opens and closes. The full body design is generous enough to clear springs up to 1.65 inches in diameter. For adjustment, they come with thick-walled adjusting nuts and 4140 steel poly locks to keep everything securely in place.

This set is a well-built option for enthusiasts looking to get the most out of their Ford small-block engine. They are designed to accommodate larger diameter springs, which is often a consideration when upgrading camshafts or cylinder heads.
