Using your Billetworkz Hybrid Shift Knob is easy. Just grab the knob and shift as you normally would with your 6 - speed manual transmission. When you're shifting, the weighted core will help you make smooth and accurate gear changes. Note that this shift knob is only for manual 6 - speed transmissions, so don't try to use it on other types of transmissions. To keep your shift knob in top shape, clean it regularly with a soft cloth. If you have the Delrin shell, avoid using harsh chemicals as they might damage the temperature - resistant coating. For the Cosmic Space Aluminum Shell, a simple wipe - down will do the trick. Enjoy your enhanced driving experience with this high - quality shift knob!
