The PROFORM SBF Roller Rocker Arms 1.6 Ratio 5/16in Pedestal Mount delivers precision valve train performance for small block Ford engine builds. This 16-piece set features full roller design rocker arms finished in blue anodized aluminum, engineered to reduce friction and improve lift accuracy across the RPM range. The 1.60 ratio geometry provides increased valve lift while maintaining stock valve geometry compatibility, making these rocker arms a direct replacement for OEM applications and performance upgrades alike.
The 5/16-inch pedestal mount design ensures secure installation on small block Ford cylinder heads without requiring modifications. Full roller construction minimizes friction losses compared to stamped steel alternatives, translating to improved engine efficiency and reduced wear on the camshaft and pushrods. The 1.6 ratio rocker arms amplify cam lobe lift to the valve—ideal for street performance, naturally aspirated builds, and moderate boost applications where stock valve lift needs to be increased without aggressive cam profiles. Blue anodized aluminum construction provides corrosion resistance and durability while keeping rotating mass lower than heavier alternatives.
These rocker arms suit builders developing small block Ford engines for street performance, bracket racing, and track duty. The 16-piece set accommodates a complete cylinder head installation. Proper valve lash adjustment and pushrod length verification are essential during installation to ensure optimal rocker arm geometry and prevent valve train problems. Compatible with stock and aftermarket small block Ford heads using 5/16-inch pedestal mounting bosses.
PROFORM is a recognized manufacturer of engine performance components, and roller rocker arm technology represents an established upgrade pathway for Ford inline engines. The 1.6 ratio sits in the middle performance range—more aggressive than stock but less extreme than ultra-high-lift ratios, making it a practical choice for builders balancing efficiency, reliability, and valve lift gains.
