Big Block Chevy 1.7 Ratio Roller Rocker Arms for Improved Valvetrain Performance

These 1.7 ratio roller rocker arms are designed for Big Block Chevy applications, helping improve valve lift, reduce friction, and support more responsive engine performance.

Built from 2024 aluminum, this rocker arm design balances strength, durability, and valvetrain stability for street performance, restoration, and upgraded engine builds.

The needle bearing design helps promote smoother rocker motion and more consistent valve control, especially when paired with compatible camshaft, pushrod, and valve spring combinations.

Configured for 7/16 in. stud applications where applicable, these rocker arms are built for proper fitment and reliable operation. Always verify rocker ratio, stud size, pushrod length, guideplate alignment, and valve spring clearance before installation.
