Using your Billetworkz weighted shift knob is easy. Just replace your original OEM knob with this one. Make sure your car is in park or neutral and the engine is off before installation. When shifting, the weighted design will give you a smooth feel, and you can enjoy the full reverse lockout functionality. For maintenance, clean the knob with a soft, dry cloth regularly. Avoid using harsh chemicals or abrasive materials as they may damage the powder - coated finish or the laser - engraved pattern and logo. Also, remember this knob is only for 6 - speed manual transmission models, so don't try to install it on CVT or automatic transmission cars.
