SBC Roller Tip Rocker Arms 1.5 Ratio 3/8in Stu

The PROFORM SBC Roller Tip Rocker Arms 1.5 Ratio 3/8in Stud (SKU: PFM66906C) deliver precision valve actuation for small-block Chevy engines seeking reliable, efficient power delivery. These roller tip rocker arms are engineered for builders and restorers who demand factory-compatible performance without compromise. Whether you're tuning a daily driver or maximizing output on a street or strip engine, this complete 16-piece set eliminates the need for piecemeal sourcing and ensures matched geometry across your valve train.

Built from durable steel construction with a natural finish, each arm features a roller tip design that minimizes friction at the pushrod interface and reduces wear on your camshaft lobes over thousands of heat cycles. The 1.5 ratio geometry provides a balanced mechanical advantage—amplifying valve lift by 50 percent relative to camshaft lobe rise—ideal for street and mild performance applications where reliability matters as much as responsiveness. The 3/8-inch stud mount bolts directly to your small-block Chevy cylinder head without modification, maintaining OEM-style installation geometry while offering superior durability compared to stamped arms.

SBC Roller Tip Rocker Arms 1.5 Ratio 3/8in Stud rocker arms suit engine builders upgrading from worn original equipment or transitioning to a more aggressive cam profile. This complete 16-piece set covers both intake and exhaust banks on a small-block Chevy, eliminating guesswork and ensuring consistent valve train performance. Installation pairs seamlessly with aftermarket or OEM cylinder heads and works across carbureted, fuel-injected, and forced-induction small-block applications where dependable valvetrain control is non-negotiable.
