The PROFORM SBC Aluminum Roller Right-Hand Rocker Arm Set with 1.5 Ratio and 3/8-inch Stud Mount delivers a proven upgrade path for small block Chevy engine builds. This 16-piece set of full roller rocker arms combines reduced friction and enhanced durability compared to traditional stamped rocker designs, making it ideal for street performance and racing applications where reliability and consistent valve train geometry matter.
The 1.5:1 rocker ratio increases valve lift by 50 percent relative to camshaft lift, extending the effective duration and lift profile of any installed cam without requiring a custom grind. Full roller design minimizes contact friction between rocker arm and valve stem, reducing parasitic losses and extending component life under high-RPM operation. Blue anodized aluminum construction provides corrosion resistance and weight savings over iron alternatives. The 3/8-inch stud mount interface is standard for small block Chevy platforms and fits within the existing cylinder head bolt pattern, streamlining installation on most SBC heads.
Engine builders and performance enthusiasts targeting small block Chevy applications—whether naturally aspirated street motors, circle track racers, or vintage restoration projects—rely on rocker arm sets to dial in power delivery and control spring pressures. This complete 16-piece set covers both intake and exhaust sides, eliminating compatibility concerns and simplifying the purchasing process. The right-hand orientation and stud mount design integrate directly into conventional SBC head castings without modification.
PROFORM is recognized within the engine building community for manufacturing quality valve train components. Roller rocker arms represent a logical step up from stamped designs when upgrading camshaft packages or increasing engine stress. This configuration strikes a balance between affordability and durability, making it accessible for both amateur builders and professional shops working within a range of budgets and performance targets.
