2AZ with a balance shaft is fine, 2AZ without balance shaft tends to vibrate.
This product is not from oroginal Japanese. At the original‑engine price—you simply couldn't afford it. Second, we've developed this ourselves, and Chinese manufacturing technology is now very mature. Third, we conduct ignition tests before shipping; we could send you a video of 2AZ ignition test. Last but the key point is that annual China installations of 2AZ typically exceed ten thousand units and so give the feedback that 2AZ with a balance shaft is fine, but the one without it tends to vibrate.
Many Chinese people have tested for you already for so many years.
