Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.

Camshaft Kits, Stage 1 LST Master Camshaft Packages, Hydraulic Roller, Advertised Duration 298/303, Lift 0.633/0.655, Lifters, Chevy, 6.2L LS, Kit

COMP Cams Stage 1 LST Master camshaft packages for GM LS applications take the guesswork out of choosing the right valve train upgrade package for your specific engine and desired performance. The "Low Shock Technology" behind COMP Cams LST camshaft packages features lobe profiles designed to maximize horsepower, while improving stability at higher rpm. These profiles are also easier on the valve springs, enhancing durability and reducing load loss. By Spintron and dyno testing these new profiles with many combinations of valve train components, COMP Cams engineers have created valve train packages that are perfectly matched for maximum horsepower and dependability in all popular LS applications with varying modifications. Stage 1 LST kits commonly add 60+ hp, depending on application.

Stage 1 LST Master camshaft packages include:
• COMP Cams LST Camshaft
• Lifters
• Timing Gear Seat or Phaser Limiter (Depending on application)
• Pushrods
• Valve Springs
• Retainers
• Valve Locks
• Spring Seats
• Valve Seals
