I guess that you may have snow on the ground up there

I will just guess, because i have the Sport front bumper & i am not about to jack up my Ram, just for for a bolt measurement

I will say that those 3 bolts would have to be 9/16ths or the Metric equivalent of 21mm ?
i won't even guess at the length

I googled to get these images

The main bolt for each can be ordered from All Mopar Parts. Check with Benny.

I purchased a 2019 Ram 1500 Crew Cab (Classic) 4x4 with 5.7L Hemi in June 2025 and wanted to add Tow Hooks. The first set that I purchased didn't fit because they were for a 2019 Ram 1500 Crew Cab (New Body) 4x4 with 5.7L Hemi. I had no idea they made the same truck in 2 body styles that year. So when I purchased the correct Tow Hooks, I started the install but when I got to installing the Main Bolts, I noticed the M12x1.50 bolts that were supplied with it would not thread more than 1/10th of a turn. I contacted O'Reilly Auto Parts but they could not identify what the bolt size was supposed to be and recommended I go to Ace Hardware which I did. At Ace, I tried a couple different Metric bolts and was able to screw the M12x1.75 bolts in about 2 1/2 turns by hand. I ended up purchasing these (M12x1.75x60) and then installed when I got home after cleaning threads the best I could with WD-40 and a rag. What I noticed was that the bolts would thread in but required more and more torque the further I threaded them in so I had to thread forward and backwards a few times and eventually (with much torque) was able to get them all the way installed. The next day, I purchased another set of these same bolts and back the first set out and replaced. I noticed the first set had some damage on a couple of the threads which must have been binding up on something (could be anything given threads were left exposed for 7 years). I installed the 2nd set of bolts with no problem and was able to torque adequately. I don't understand for the life of me why the M12x1.50 bolts wouldn't thread because that is what came with the kit and that is what Ram indicates the threads should be. However, given I couldn't get more than 1/10th of a turn with the supplied bolts, I knew something was drastically wrong. Has anyone else experience this headache? This should have been a 1 hour job which turned into a 5 hour job given the issue with thread size.
