This bolt is a grade stronger than the OEM bolt. Direct replacement for my truck. Both of mine bent over between the nut and the key. Not the best design for sure.2015, 2500/3500 Chevy/GMC

There are a few options when trying to purchase new torsion bar adjustment bolts, and nothing telling you which ones are a match; they all look, in the photos to be the same, but in fact, are different sizes. Next time, I'll just go the to parts store with the one ones and be sure to come back with the correct ones. Not worth the savings!

Not even close! Now I have to try and chase down the nut these bolts may fit. Don’t waist your time.
