## Product's reviews:
- Spur gear - Our Yellow Karcher "Duckee" steers once more.
The spur gear works as advertised!!!
- Free freight ! - Easy to do business with
- Nice sprocket - sprocket is very nice.
- 21 tooth 12 dp spur gear - The 21 tooth 12 DP gear I bought arrived very quickly.
It was exactly what I needed to fix my RV slide out.
I had to machine it to fit, but I knew that when I ordered it.
VERY SATISFIED!!!
