The M46 shifter knob is notorious for poping off on those critical 1st to 2nd or 3rd to 4th power shifts. If you are sick of your knob falling off, the GilRacing M46 replacement knob is just what the doctor ordered. The fit and finish is superb, and the button has an excellent feel. Once you try the knob, you will wonder how you ever lived without it! Currently a clear anodized aluminum knob with a hard stainless steel base is being offered. eMail Gil Racing with any questions.
