About to do some serious suspension mods to the 2025 GT. Practically every bolt and nut requires the replacement according to the Ford factory manual because they're torque to yield. I've been doing this along time, Fox body, SN195 etc. I've never seen this. Calling the dealerships looking for these bolts and nuts, none of them are in stock which tells me their not, as a routine replace according to the Ford manual, just reused. Guidance I've encountered is if it has a torque spec it's not torque to yield, just torque and move on. THOUGHTS?

They have thread locker on them which is "used up" the first time they're installed. They are not "torque to yield" in any sense, they're just "don't re-use them". Of course, if you do re-use them, like most of us do, they'll be fine if torqued properly.

In my past inquiries regarding the one time use bolts, I've found the same thing that they are not torque to yield, and some, but not all, of them have threadlocker. If it has threadlocker, I am sure to use it when I reinstall, but nothing I've read indicates there is a real necessity to purchase new bolts each time. For example, the rear camber arm to frame bolt says to discard and replace when removing the arm, yet it has to be loosened and to adjust the camber, and the shop manual says nothing about replacement when loosening and tightening for adjustment. I bought a bunch of the suspension and brake bolts the first time I worked on changing out parts, but discovered there was no reason to replace them. I still have the bolts in the bag and did not use them.

After some exhaustive research, including this forum and others, here's the deal. These are not torque to yield, they wouldn't have a torque value if that were the case. This is a liability thing on Fords part and perhaps a way to make a few extra bucks. This also centers around thread locker and the use of it. I opted to use blue loctite as I always do, on all these bolts and call it a day. Some of these bolts, according to the Ford Manual are required to be replaced, yet many of them are loosened during routine alignments and other soft maintenance.
At the end of the day, all were reused with blue loctite applied and torqued to factory specs.

I thought this has been covered and maybe I missed your post. You are 100% CORRECT. IMHO its a money grab for the stealerships

For the longest time I thougth all torque to angle bolts (initial torque + angle finish) were a torque to yield bolt. But, I've recently learned otherwise. So, how does one identify a TTA vs TTY bolt, vistually?
