The Story
Upgrade your GM LS engine with this stage 4 hydraulic roller camshaft engineered for street and performance builds. Designed to improve airflow, throttle response, and power across the RPM range, this camshaft delivers a stronger, more aggressive performance profile.
Performance Gains & Powerband Optimization
With 222° intake / 232° exhaust duration, 0.604" intake / 0.587" exhaust lift, 108° lobe separation, this camshaft profile is designed to increase horsepower and torque while matching the intended powerband of 1,500-6,500 RPM.
Hydraulic Roller Valvetrain Design
Hydraulic Roller construction supports stable valvetrain operation and efficient performance in modern GM LS engine combinations.
Durable Performance Construction
5150 Induction Hardened Chromium construction provides strength and reliability for demanding street, strip, and performance engine builds.
Installation & Supporting Components
Proper tuning, piston-to-valve clearance verification, and matching valvetrain components are recommended. Recommended valve springs: 0.660 in..
