Description

The Genuine GM 12600936 Rocker Arm Pedestal Stands are factory-original replacements for 2007 and newer LS engines with rectangle-port cylinder heads. Manufactured to GM's precise specifications, these stands ensure proper rocker arm alignment and maintain accurate valvetrain geometry. They are ideal for replacing damaged or missing OEM stands and are also necessary when converting cathedral-port engines to LS3 or rectangle-port cylinder heads. These stands offer the same strength and durability as original equipment found on high-performance applications like the LS3, L99, and LSA engines.
