New from COMP Cams – the LST Camshafts for GM 6.6L Duramax Diesel Engines. These cams use LST (Low Shock Technology) lobes in order to create greater power potential and increased valve train durability. See more details below.
COMP Cams expands its GM 6.6L Duramax Diesel camshaft selection for 2001-05 (LB7/LLY) and 2006-16 (LBZ/LMM/LML/L5P) applications with the addition of LST (Low Shock Technology) lobes in order to create greater power potential and increased valve train durability.
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.
Organized into stages that allow you to choose your level of performance, Stage 1 Camshafts are No Springs Required and run well with the factory or a performance tune. Stage 2 and 3 camshafts require a COMP Cams #26125 Beehive Valve Spring Kit upgrade but do produce the greatest potential for additional power and RPM when matched with maximum effort tuning.
- Stage 1 Cams are No Springs Required for ease of installation and run well with factory or performance oriented tunes
- Stage 2 and 3 cams offer the highest potential HP & torque gains when matched with performance tuning
- Low Shock Technology lobes reduce valve train shock and are easy on springs, allowing higher RPM, improved durability and reduced load loss
- Beehive Valve Spring Kits available for more power and RPM production
