SBC Rocker Arm Set - 1.5 Ratio 3/8 Stud

The SBC Rocker Arm Set - 1.5 Ratio 3/8 Stud is a complete rocker arm assembly designed for small block Chevy engine builds and high-performance rebuilds. This 16-piece set delivers the mechanical advantage needed for aggressive valve timing and lift profiles, making it essential for enthusiasts upgrading from stock components. Whether you're building a street performance engine, preparing for competition, or restoring a classic Chevy platform, this rocker arm set addresses the demand for reliable, precision valve train geometry.

Engineered from steel for durability and designed with a 1.5:1 ratio, this rocker arm set multiplies camshaft lift by 50%, allowing smaller cam profiles to produce greater valve lift at the cylinder head. The 3/8-inch stud mount provides secure attachment to small block Chevy cylinder heads, while the ball-and-nut hardware configuration ensures precise pivot geometry and consistent valve train clearance. Nitro Rockers construction delivers impact resistance and fatigue strength critical for sustained RPM operation, preventing deflection that can compromise valve timing accuracy and engine efficiency.

Performance builders, engine rebuilders, and weekend racers benefit most from this rocker arm set when transitioning to aftermarket camshafts or optimizing stock cam packages for maximum street or strip performance. Installation requires standard pushrod geometry verification and valve lash adjustment—critical steps that determine engine reliability and power delivery. The set's 4.35 lb weight and compact 5.4 x 5.3 x 7.7-inch dimensions fit standard small block Chevy applications; verify stud hole pattern and center-to-center spacing on your specific cylinder head before purchase to ensure proper fitment and clearance with your intake manifold and valve covers.
