Chevy LS3/L92 1.7 Ratio Shaft Rocker Arm System for Improved Valvetrain Performance

These 1.7 ratio shaft rocker arm system are designed for Chevy LS3/L92 applications, helping improve valve lift, reduce friction, and support more responsive engine performance.

Built from stainless steel, 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 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.
