TOYOTA Crankshaft Key; FR - SU001A1616

The crankshaft key, also known as a Woodruff key, is a small but vital component in your Toyota engine. It fits into a slot on the crankshaft and a corresponding slot on the timing gear or pulley, preventing rotation relative to the shaft. This precise alignment is critical for maintaining correct ignition and valve timing, which directly impacts engine performance, fuel efficiency, and overall drivability. When the crankshaft key is worn or damaged, it can lead to timing issues, misfires, rough idling, and even significant engine damage if left unaddressed. This replacement key is designed to meet or exceed original equipment specifications, ensuring a perfect fit and reliable operation for your FR Toyota model. Regular inspection and timely replacement of this part can prevent more costly repairs down the line.
