Bought some oem cummins bolts from them and got two day shipping and received them when I was supposed to. The first invoice I got had some incorrect information on it, but they called my cell phone before I even got the email and told me what was going on and that they were sending the right one. Most companies would just send a second one and let you be confused.

CPP Diesel literally has every part you can imagine, and the all around ordering process was extremely easy. Will definitely be back!
