Freeze Plug 3 Pack - E.D Billet - Cummins 12v, 24v, 5.9L, 6.7L 1989 - Present

Fast shipping,Quality of the plugs themselves are great! The bars on other hand ,only one of them the threads were good the other 2 crossthread right out of the bag. I would recommend buying a tap of the same thread and just tap it to clean the threads before install.

The bolts were not the same thread as the bars. So had to buy bolts and make new bars

I wish I could give 0 stars as these things are TRASH. Got around to using them and the pictures speak for themselves. Bolts appear to have been so much too long that they bent the bolt. Went to torque like all was well. Never felt an resistance. No other brand I used had this issue. Not one mile on them and all 3 are ruined and I'm praying my cylinder jackets aren't trashed. PURE GARBAGE. Threads were junk from get go as well. Never again.

Everything listed by other customers are true. Thread pitch is 100% different between the retainer and bolt. Cheap quality!!!

They came a week early so I was happy about that took them out the box and put them together and wanted to make sure that everything was going to work before installation and something going wrong well all 3 bolts broke off so a huge disappointment and I can’t drill and retap them cause the holes in the plugs so had to buy metal and new bolts

Not sure how an “engineering” company doesn’t understand how to tap a hole but the bolts don’t properly thread into the retainer. Didn’t check before I started threading the first one in and got to far and broke the bolt out trying to remove it. Spend the extra $25 and get the kdd ones.
