Speedmaster 350ci SBC DNA Stud-Mount Aluminum Roller Rocker Arms
Speedmaster DNA roller rocker arms are the toughest and most innovative rockers they’ve made. Crafted from certified aircraft-quality, heat-treated aluminum, they’re matched to massive, precision- ground trunnions for superior durability and optimized rocker arm geometry that evenly distributes the load for maximum strength. DNA rocker arms also utilize oversized needle roller bearings for better load distribution and longer service life. These 1.5 Ratio 7/16″ stud-mount rockers can withstand valve spring loads up to 360Ibs. The extruded body has a tensile strength of over 60,000 PSI.
