Complete Kit: This camshaft kit (OE: 12625437, SP011-16) comes with 13 essential components, including the camshaft, lifters, lifter bases, pushrods, springs, timing cover gasket, front crankshaft seal, cylinder head gasket, water pump gasket, and more. All core parts are designed to match OEM specifications.

Enhanced Wear Resistance: The camshaft, lifters, and pushrods are made from durable grey cast iron, offering excellent wear resistance and fatigue strength. They can withstand thousands of impacts per minute in the engine, reducing wear on the contact surfaces between the cam lobes and lifter pillars.

Increased Strength: The cam, after high-frequency hardening, has higher density and hardness, enabling it to resist the corrosion of engine oil and coolant in harsh operating conditions.
