quality sprocket
I bought a cruiser bike with a KT coaster brake and KT sprocket. The sprocket was warped and the shape of the teeth was primitive. It was not meshing properly with the chain and making lots of loud ugly noises. The Shimano sprocket was a perfect replacement and everything is working quietly and smoothly.

Sure beats the 20 tooth sprocket that came on my bike. I needed more gearing for flat and downhill riding.

Excellent, higher ratio achieved!
Easy installation, and a perfect swap for my old cog. Moved down to the 16T version and now have some use out of the lower gears on my Nexus SG-8R31 (before they were way too easy). Now it's actually difficult to use the higher gears which was a welcome change.
