## Product's reviews:
- 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!!!
- Great prices and quality products - Your products are not only affordable, but they are also priced very fairly and competitively & always ship out pretty quickly. You have gained a new regular customer and stolen us from one of our regular distributors without even trying. Thank you for being awesome! Not to mention the free shipping over $100 perk is super appreciated as we not only are saving money per item, but we are also able to buy in bulk without the additional burden of freight/shipping costs.
THANK YOU!! :)
