2011-2016 Duramax EGR Blocker Plate (75111)

Had a great experience with Dirty Diesel Customs in sense of ordering my part, shipping and a follow up when I received the part. Within 15 minutes I had the part in, but then ran into a problem in the tightening sequence of the bolts. A video led me astray and now I have a bolt broken off down in my egr cooler. No fault but my own for listening to that video rather then doing what I knew was the right way to tighten everything down. Now I’m into a process to try and remove the broken bolt plus the egr cooler. If it wasn’t for that bolt breaking I would have had a five star experience. Only thing I could say that could be done to save the next guy down the road from going through what I am currently, is to provide installation instructions even tho it’s straight forward. One picture and some instructions could have saved me hours of work and possibly a thousand dollars if I can’t get the bolt extracted out of the egr cooler. Thanks for reaching out and checking in, like I said everything was great on your end and I would recommend anyone to go use your site for outfitting their diesels Mitchell Strader

Fits good, bit of a pain to get the vertical bolts back in as the block plate shims it over a bit, otherwise it worked fine.

Installed by cartwright auto Repairs and truck runs and drives the same! so glad to have the CP3 conversion done with the blocker plates on EGR. now my Duramax is ready for many reliable KLM! Thank you.
