This is a new Brass shift knob for any manual transmission and 3/8"-16 shift rod.  It is weighs in at about 540 grams. If your looking for a weighted shift knob. Look no further. This is a direct fit/replacement for the boring stock shift knob. It's made from brass 360 material and has a 3/8"-16 tapped hole in it.  It's finished to produce a nice brushed brass finish that has a good grip and really looks sharp in the interior.   This particular design has a diameter of just under 1.5" and is 3" long. You'll notice that the bottom diameter is large enough to keep the shift boot tucked down and away from your hand.  The top is fully rounded for a nice place for your thumb to rest. The lowered shift knob height, shape, and finish all contribute to a secure and comfortable feeling in your hand as your making your way through those gears.  The shift knobs are manufactured right here in the U.S.A. by a fellow car enthusiast.  A perfect gift for that car owner in your life!  If you don't like this particular design, stay tuned, additional designs will follow.
