The item was shipped and received in the time frame stated. The quality was great, and works well on my truck. I will order more from Diesel Ops.

I don’t like how they advertise 10% military discount and then once your military status is approved, only then did they tell you of the numerous brands to which the discount doesn’t apply, which was most of the brands and including all kits/packages. If I hadn’t already built my cart the previous week, I would’ve gone somewhere else for an actual discount off my purchase, but I just wanted to get it purchased and done. On the positive side, the people I spoke to you over the phone or nice and helpful, and I like how installation guides were given via email (and on website) for every ordered part
