Chevrolet Express 3500 Camshaft - COMP Cams - LST Solid Roller Stage 1 (10-17) is a purpose-built camshaft for enthusiasts upgrading Gen III LS 3-bolt applications. This Stage 1 LST solid roller profile is intended for drivers who want stronger mid- to high-range power while retaining stock piston compatibility.

Specifically engineered for LS 3-bolt engines, the COMP Cams LST Stage 1 offers a conservative solid-roller timing that works with stock pistons and factory valve reliefs. The profile is tuned to improve torque and horsepower through the 3000–7000 RPM band without requiring piston deck changes. When combined with CK or MK kits (matched valvetrain components), the valve train is rated to remain stable to around 7,500 RPM, giving reliable control for higher rev use while maintaining compatibility with many street and weekend performance builds.
