The C5 & C6 factory clutch systems have had issues with the clutch pedal going to the floor under high RPM use and not returning to the correct position. The engineers at Lingenfelter have come up with a clutch return spring kit that forces the master cylinder orifice to open and allows the fluid to flow back into the master cylinder, which resolves the clutch pedal sticking issue. This kit also speeds up the application of the clutch after the pedal is released. This is cheaper and easier to perform than any other repairs or modifications.
The Clutch Pedal Return Kit includes a stainless steel spring with a dampening sleeve to prevent noise. This kit fits all C5 1997-2004 & C6 2005-2013 Corvette applications.
