10th Gen Civic Si 420g Shift Knob by Boomba Racing

These shift knobs feature a precision CNC machined brass core for added weight as well as a black delrin shell for durability, excellent appearance and temperature management.

420g vs. the 180g of a stock knob. A heavier shift knob puts the weight towards the end of the shift lever. This increased momentum while shifting gives you a greater mechanical advantage, allowing for a much more positive feeling throw when rowing through the gears.

The delrin shell features a cap with an engraved shift pattern. Since these knobs are delrin, it prevents the surface of the shift knob from getting too hot in the summer and too cold in the winter. These shift knobs make a great addition to your Tenth Gen interior!
