Using your Billetworkz Fusion Weighted Shift Knob is easy. Just grab the shift knob firmly and smoothly move it through the gears as you drive. Remember, this shift knob is only for 6 - speed manual transmission models, so don't try to use it on CVT or automatic cars. For maintenance, clean the leather part gently with a soft, damp cloth. You can also use a mild leather cleaner occasionally. For the metal parts, wipe them down with a dry cloth to keep them looking good. Keep it away from harsh chemicals and extreme temperatures to ensure its long - lasting performance.
