Upon needing a special pulley application for a engine conversion on a piece of machinery, I found MDS had all of the bushings and pulleys that I needed to make a perfect fit and get the machine up and running. The order came in very timely manner, and packaging was perfect. I recommend this company to anyone needing good service and availability. Thanks to them everything went smoothly on my Machine repair.

I was extremely happy with the pricing and quality of the gears I ordered. Shipping was fast, got them sooner than expected.

Second time I have ordered from them. They send what you order and their measurements are correct.

We had a slight hiccup with the order, but Noah came through like a true champion.

This is the epitome of great customer service!
