The COMP Cams Stage 1 LST solid roller camshaft for 2000+ GM 6.6L Duramax engines is a No‑Springs‑Required (NSR/NTR) grind that operates with factory springs and typical factory tune levels. Its Low Shock Technology lobes increase airflow and throttle response, delivering usable performance gains across the powerband while remaining compatible with stock valve‑train hardware and conservative tuning.
