Description

The GM Genuine Parts 12630089 Valve Lifter Guide (commonly referred to as an "LS/LT Lifter Tray") is an authentic factory Original Equipment (OE) high-strength composite plastic guide molded specifically for non-AFM/non-DOD hydraulic roller lifter configurations. Secured to the cylinder block bore valley via a single center bolt, each guide houses and aligns four roller lifters to keep the roller wheels parallel to the camshaft lobes and prevent lifter rotation. Serving as the standard factory lifter tray for non-DOD LS and Gen V LT engines, it is also the mandatory lifter tray specified when performing AFM/DOD delete conversions on Gen IV LS and Gen V LT engines.
