This is a OEM GM genuine C6 Corvette shift knob.

These knobs will only fit 2008-2013 C6's. GM changed the bottom of the knobs and they are not designed to fit with the 2005-2007 factory shift boots.

This knob has the 2008 smooth aluminum on the top shift cap where the shift pattern is. We do offer the checkered patterned shift knob as well
