The LST™ Camshaft Series uses the newest and most advanced lobe designs from COMP Cams®. These new lobes provide the potential for major increases in power and torque in Duramax engines when combined with the appropriate tuning. The “Low Shock Technology” features lobe profiles designed to maximize additional engine airflow, which reduces harmful EGTs, while improving stability at higher RPM. These profiles are also easier on the valve springs, enhancing durability and reducing load loss.
