Buick Rainier Engine Camshaft - COMP Cams Stage 1 LST 223/225 Hydraulic Roller Cam (2004–2007). A focused upgrade for LS-based 5.3L Rainier builds that want turbo-ready performance with dependable street manners.

The 223/225 hydraulic roller profile delivers crisp response and a broad, usable powerband. It supports the 2004–2007 Buick Rainier 5.3L and other LS 4.8/5.3 platforms. For a complete solution, pair it with COMP CK or MK kits for matched valvetrain components; MK kits are available with 24x or 58x timing sets.
