Is that the Nissan bug deflector? Or another one? I am at the point now where I am tired of getting nicks in my hood. Truck looks good!
I could not tel you anymore. I looked at the list on my first post and I did not see it there so hmm. I think it is since I bought Nissan hood and windows then sold the windows and got weathertech windows. I'm sure it is somewhere in this build or maybe on the other sites build but i'm not going over there already went there today for the first time in a year.
Why pick up different size shackles? Obviously for different applications.. But what are those applications?
The reason for the different size shackles is for there WLL (working load limit). I don't know if you know this but it is a very important fact so feel free to skip the details below.
Details: WLL (working load limit) is the limit which the shackle or recovery strap supply company applies to a device which they consider safe. The breaking load (usually 6 times the WLL) is where the shackle will fail. Along with this the maximum proof load (where they test it too) is ~2x the WLL. All shackles that are rated for a load have this stamped on them. Even the little ones you find in a store if it is meant to hold weight it will be on there. This value is given in tons. As in (WLL 6 1/2T) This ton rating is actually a metric ton. So my small shackles are rated for 4 3/4T=10,450lbs or the larger shackle 6 1/2T=14,300lbs. I also have two that rated at 8 1/2T=18,700lbs. Also keep in mind this is for a direct pull. When a shackle is used in a indirect pull. As in you connect two recovery straps to two different treas and connect your winch to the middle they are rated for less. 45 degrees is 70% of WLL and 90 degrees is 50%.
The reason as you describe is correct. Different applications. In the above pictures you will notice a shiv. While using my current winch it can pull with ~9,000lbs which any of my shackles can be rated for. Once the shiv comes into play and you hook your winch back to your vehicle it doubles this force. or in another words my winch can pull ~18,000lbs. Now yes none of the shackles should break at these forces but they could start bending. Or if a shackle ends up sideways it's rating is half and it could very well break or deform. Or if I have to put two recovery straps between trees to get a better winching point the ratings goes down as described above. For this reason I would rather be safe then sorry.
In the end it is all about safety. The 3 different shackle sizes i carry are 1", 7/8", 3/4". Anything small is worthless and I think most people should have at least 1 7/8".
