High Compatibility: Norris NSR camshaft, compatible with Norris trucks 1999-2013 GM Gen3/4. Fits LS truck engines and is suitable for engines with 4.8L, 5.3L, 6.0L and 6.2L displacements.
Precision restoration: Engine camshaft OE: 12625437, SP011-16. Fully matches the original part. Kit does not include springs.
Improved wear resistance: The cam is made of durable gray cast iron, which offers wear resistance and fatigue resistance and can withstand thousands of strokes per minute in the engine, reducing wear on the contact surfaces between the cam lobes and lifter posts.
Increased strength: After high-frequency hardening, the camshaft has higher density and hardness, which allows it to resist corrosion from engine oil and coolant under harsh operating conditions.
Restore Engine Performance: Our engine cam systematically addresses performance degradation and wear caused by engine aging, extending engine life and improving overall performance.
