Hummer H3T Engine Camshaft Kit – COMP Cams Stage 1 LST 58X Master Cam Kit for 4.8/5.3 turbo (2009–2010). Purpose-built for LS turbo use, this kit delivers a matched cam and valvetrain solution for H3T 5.3L and other 58X-based 4.8/5.3 projects.

Ideal for “cam only” turbo builds with unknown back pressure, the Stage 1 LST profile is paired with components selected for stability and reliability under boost. The kit includes lifters, pushrods, springs, retainers, locks, seats, seals, and a 58X, 4‑pole reluctor timing set for late-model LS electronics. If you need a 24X, 1‑pole setup, see part M54-330-24.
