Hummer H3T Engine Camshaft — COMP Cams Stage 1 LST 223/225 Hydraulic Roller Cam (2009–2010). Built for LS 4.8/5.3L turbo combinations, it delivers a well-balanced street profile.

This Stage 1 LST is a popular choice for cam-only turbo builds with unknown back pressure. For the 5.3L H3T and other 4.8/5.3L GM LS platforms, it supports quick spool and solid midrange while keeping drivability in check.
