Steps for installing the product:
1. Detach the gear shift knob from the original car. Usually, there are threaded teeth on the gear shift rod, which can be unscrewed directly. Some may have a clamp. (Note: Some car gear shift knobs are fixed to the gear rod and cannot be removed!)
2. Next, secure the lower ring of the extended shift knob onto the original car's shift rod, attach the shift knob, adjust it to the desired position, and tighten the screws using the provided hex wrench.
