Description

The GM Genuine Parts Valve Rocker Arm (part #12681275) is engineered to meet rigorous GM standards for LS engine platforms. Designed as a direct replacement for part number 10214664, this non-adjustable rocker arm features a 1.7 rocker ratio and a bearing trunnion for smooth operation. This rocker arm is suitable for the intake and exhaust positions on LS1, LS2, and LS6 engines with cathedral port cylinder heads.
