Great service and shipping. Kept in touch whole time.

Its nice to have an accurate website!

Quick prompt service they had the item in stock!

I have a Cummins with a G56 trans. I’ve used this gear oil twice now and have had no problems. I’m currently sitting at 150k miles. I’m in some of the Cummins FB groups and I always recommend this product.

I’m very pleased with ECD and having the part in stock and ready to ship. Also, I received my part in a timely manner. I’ll purchase more parts from ECD in the future.
