COMP Cams 17043-1 High Energy Aluminum Roller Rocker Arm 1.6 Ratio Ford Small Block

The COMP Cams 17043-1 High Energy Die Cast Aluminum Roller Rocker Arm delivers an affordable performance upgrade for Small Block Ford 289, 302, and 351 Windsor engines. This individual rocker arm features a die-cast aluminum body that is larger than stock, providing superior strength while maintaining lightweight construction for improved valvetrain response.

Key Features:

• 1.6:1 rocker ratio for increased valve lift
• 3/8" stud diameter mounting
• Full roller design with needle bearing fulcrum and roller tip
• Die-cast aluminum construction for optimal strength-to-weight ratio
• Reduces friction compared to stock sliding rockers
• Lowers oil temperatures for improved engine response
• Snap rings secure trunnion and bearings in place
• Designed for street performance and moderate race applications

The specially engineered needle bearing fulcrum and roller tip create significantly less friction than factory sliding rockers, resulting in lower operating temperatures and increased horsepower. The stiffer, more durable design withstands high valve spring loads up to 350 lbs. open spring pressure while providing the added valve lift needed for performance camshafts. Sold individually for replacement or custom valvetrain setups.

Application Note: Fits Small Block Ford engines with screw-in studs. Not for use with guide plates. The larger-than-stock body may require valve cover modifications for proper clearance.
