Today we're going to review part number TRFA73Z916DLNZ. This is the TruRyde zinc shackle bolt with the lock nut for double-eye springs. This shackle bolt is a 9/16" diameter, and it is used to mount your double-eye leaf springs in your front hanger or your rear-suspension hanger. The lock nut is included. The shackle bolt and nut is a corrosion-resistant zinc finish. It is a 9/16" diameter, I mentioned, and the length of it, this is for 3" long.
So basically the way you would measure that is if you measure from under the head of the bolt to the very end of the bolt. And you can see there that it's 3". One other little item we need to mention to you is, this is a lock nut. It may look like, just by looking at it, a standard nut that attaches to the bolt, but this is what is called a distorted lock nut. By the distorted they mean that if you look at this side of the lug nut, it is actually oval shaped.
If you look at the bottom, it's actually normal round shape. What they do is they crimp the very top of this, and you can tell that by if you look at the sides you'll see crimp marks right here, and then 180 degrees crimp marks on the other side. So they basically crimp this and squeeze it a little bit to distort the top of the bolt, and that will give it it's locking feature. So when this lock nut is installed onto your shackle bolt, what you want to make sure is that these crimp marks right here that are at the top are facing to the outside. So in other words, make sure the crimp marks are facing to the outside.
And you'll start it, and it will start about one thread. It won't start a whole lot. It will seem like the threads are cross threaded or something. but just go ahead and start that way. Actually, what you'll need to do is once you install your lead spring in your suspension, and then you're going to put the nut on there, just start it like that.
Make sure your suspension is all lined up, everything's ready to go before you tighten this down. Now once it's all ready to go, go ahead and tighten this down, and as you tighten this down, it will lock onto this bolt when it gets to this distorted part. So that is very critical. If you try to do it with the crimp marks facing inwards, it just won't start because it's distorted and the threads will not start. So a little tip there is to just make sure those crimp marks, that you can see right here, are facing out. It'll start maybe one thread, not a whole lot, and then you'll be ready to install the shackle bolt. Hope that helps you, and that should do it for review on part number TRFA73Z917DLNZ.

9/16" Diameter spring-retainer bolt is used to mount double-eye spring in front or rear suspension hanger. Locknut included.Wth rusted out leaf springs on my trailer but with zero experience replacing them, I contacted etrailer and Shawn was very helpful in selecting the right parts and taking me through the process. She was patient in terms of helping me take the right measurements and suggesting the bolts and pieces I needed to do the job right. Everything came well packaged and complete two days later. An hour after that the springs were in my trailer and now has a boat sitting on it. Thanks! 423135
Just received the shackle straps and bolt. They look excellent and superior as the originals were only 1/2 " dia. and strap holes elongated by 1/4 ". One was worn thru. Also, straps are at least 1/32 thicker than originals. You phone person that took the order did an excellent job and very patient. First trailer suspension I have overhauled so some difficulty in describing what I even needed. Should be back on the road in a day or so. tks bob 738002
