Had a mix up at first and got the wrong part but Sinister staff was very helpful and got the right one on the way before I had a chance to send the wrong one back. Very good quality part and it looks great on the old 12 valve Cummins

Got it quick and easy

It was my fault that I ordered the wrong part. The return process and the customer service was great though. I couldn't be happier with my experience.

Great service

Fast shipping. And I love the loyalty points and military discount!!!

Product description does not match. It’s ugly and not shiny! But it works and it takes that drone out.

Awesome service and shipping! Thanks, Gary
