Speedmaster Roller Rocker Arms
Roller rocker arms add horsepower to your engine by limiting power loss that occurs in the valve train. To cut down the parasitic drag that takes place in the rocker arm, the metal-on-metal contacts and pivot points are replaced with roller bearings for smoother operation.
Speedmaster DNA roller rockers are a pedestal mounted, full-roller design CNC machined from 2024 heat-treated aluminum. Needle bearings are used on pivot points for better load distribution and rocker arm bodies feature an anodized black finish. Specifications vary by application, and this set, for Ford 289, 302 and 351 Windsor engines, uses a 5/16-inch stud and 1.6:1 ratio for improved valve lift.
