SBC Roller Tip R/A's - 1.6 Ratio- 3/8in Stud

The PROFORM SBC Roller Tip R/A's with 1.6 Ratio and 3/8in Stud (set of 16) represent a purpose-built valve train upgrade for small block Chevy engines demanding reliable, high-lift rocker arm performance. These roller tip rocker arms are engineered for builders and enthusiasts who run aggressive cam profiles, forced induction, or naturally aspirated high-revving combinations where reduced friction and precise valve actuation directly impact reliability and power delivery. A complete 16-piece set eliminates the guesswork of partial upgrades, ensuring symmetric valve train geometry across all intake and exhaust positions.

Roller tip design substantially reduces friction between the rocker arm and valve stem, translating to lower parasitic losses, cooler valve springs, and more consistent valve timing throughout the RPM range. The 1.6:1 mechanical advantage ratio provides meaningful valve lift multiplication suitable for street performance and circle track applications where durability cannot be compromised. Steel construction with a natural finish ensures longevity in high-temperature environments, while the 3/8-inch stud mount directly interfaces with factory small block Chevy cylinder head configurations, making installation straightforward on both original and modern SBC platforms without requiring machine work or additional hardware.

Professional engine builders, bracket racers, and street enthusiasts upgrading carbureted or fuel-injected small block Chevy combinations will find this set invaluable for maximizing the efficiency of performance cam grinds. The complete 16-piece set simplifies inventory management and ensures matching geometry across all cylinders—critical when dyno-tuning or pursuing repeatable power figures. Compatible with both traditional and roller cam profiles, these rocker arms serve as a direct bolt-in replacement for worn factory units or inferior aftermarket alternatives, requiring only basic push rod length verification during installation to ensure optimal geometry.
