This is a good ring and gear. There are many manufacturers that produce rings and gears. Just choose a reputable manufacturer and you're good to go. They are all very similar in quality and finish if you choose a reliable manufacturer. However, the actual installation of the ring and gear wheel is more important than the manufacturer. The garage or workshop where the installation is done is very important as improper installation will ruin the ring and gear! Do your research and find a reputable shop that will do good installations.
