GMC Envoy Engine Camshaft Kit – COMP Cams Stage 1 LST 58X Master Cam Kit for 4.8 and 5.3 Turbo (2005–2009). A streetable turbo cam package built for LS-based 4.8/5.3 applications that use the 58X crank trigger.

Designed for cam-only turbo builds with unknown back pressure, this kit targets crisp response, stable vacuum, and a broad midrange while supporting strong performance under boost. It includes a 58X (4-pole) timing set and matched valvetrain components for dependable valve control in demanding LS turbo setups. Ideal for 5.3L GMC Envoy and other LS platforms requiring 58X; if your engine is 24X, use kit M54-330-24.
