Shift knob machined from solid pure titanium, with titanium's characteristic feel, color and substantial weight. Normally made to order, with approximately four to six weeks lead time. Minor size changes are possible but may take longer. The source notes that titanium is heavier than duralumin by volume but requires less material to achieve equivalent strength.
For gated AT applications such as BP/BL, manufacturer price JPY 24,800 excluding tax / JPY 26,040 including tax. The source lists two sets remaining and states that rising production costs limit sale at that price to the two remaining pieces. Specifications match the normally sold knob except for the stated material.
K2GEAR also offers individually commissioned parts, with specifications, prices and lead times determined by the project, including aero, exhaust, machined duralumin shift knobs and suspension.
