Buick Rainier Engine Camshaft Kit - COMP Cams Stage 1 LST 58X Master Cam Kit for 4.8 and 5.3 Turbo engines (2004-2007). Built for LS-based turbo builds, this master kit pairs a proven Stage 1 LST profile with matched components for a reliable, straightforward cam swap.

Ideal for cam-only turbo projects with unknown back pressure, the Stage 1 LST balances street manners with responsive spool while prioritizing durability under boost. This 58X version includes a 4-pole reluctor timing set; if your engine uses a 24X crank reluctor, see part M54-330-24. Designed for GM LS 4.8 and 5.3 applications, including Rainier 5.3L builds, the kit’s matched valvetrain hardware reduces guesswork and promotes correct geometry and sealing.
