High Compatibility: Our camshaft kit is compatible with 1999-2013 GM Gen3/4 Norris trucks. Fits LS truck engines, suitable for 4.8L, 5.3L, 6.0L and 6.2L engine displacements.
Complete Kit: Camshaft OE: 12625437, SP011-16. This camshaft kit includes four components: camshaft, springs, valve seals and valve cones. All core parts are designed to match OEM specifications.
Improved Wear Resistance: The engine camshaft is made of durable gray cast iron, providing wear resistance and fatigue resistance. They are designed to withstand thousands of strokes per minute in the engine, reducing wear on the contact surfaces between the cam knobs and lifter posts.
Increased strength: The truck camshaft, after high-frequency hardening, has higher density and hardness, which allows it to resist corrosion from engine oil and coolant under harsh operating conditions.
Restore engine performance: The camshaft kit is designed to address extensive performance degradation caused by aging valvetrain, especially for targeted repairs on engines with high oil consumption or high mileage.
