Leaf spring eye bolt

Yea your probably right. I am just going to buy the ones from rockauto

GM ones may be affordable

Never reuse u-bolts. They're designed to stretch when torqued: 1 time use only!!

he was talking about the eye bolts. Im sure his picture was one he just took of the hardware after removal
and when did they start using TTY u bolts?

I've used grade 8s from the hardware store in that location for lifted, lowered, and stock height, Jeeps, blazers, burbs, and duallys. Never had an issue.

12.9 may be more appropriate but i have no doubt thats true

Doesn't the higher tensile strength of the grade 9 bolts make them more brittle than the 8s? Theoretically anyway?

Since when? Going through all my notes on the part number 15529595 which is OEM for my truck, they don't specify TTY. I'd love to see where you got your information.

Even on the blueprint of it does not show TTY.

Grade 8-s are fine for modified leaf packs, I had to chuck them up in a drill press and round off the hex heads slightly to make them fit in the spring perch hole in my 10+1 setup in my snow plow truck this summer.

If its a direct oem replacement, I agree its cheap insurance to have the right bolt for the intended purpose

Unless left loose and secured with a locknut, every bolt is designed to stretch when torqued. The question is whether they were torqued to their yield strength. I seriously doubt the u-bolts were torqued to yield. Check carefully for wear, corrosion, and cracks and reuse.

 

[Nad_Yvalhosert]

They are NOT torque to yield. I never said they were torque to yield. They are stretched during proper installation and put under tension. Thus not reusable

I know it sounds like it, but.. semantics. Still, they're NOT torque to yield.

That's why I have some used ones, LOL
