This Shift knobs weighs in at 448g. The reason behind the heavy knob is because it gives the impression of a "satisfying" throw into gear. Each color has been individually engraved and power coated as well as quality controlled by TJ.
PLEASE DOUBLE CHECK YOUR THREAD PITCH BEFORE PURCHASE.
Black Knob - this finish has a bit of texture with it. With this, you can ensure that your hand will not slip or get sweaty :)
Red Knob - this finish isn't smooth but it also doesn't have as much texture as the black knob. Its somewhere in between.
Purple Metallic Knob - this finish is 100% smooth and feels more like a pool ball.
