Can 3-1/2" Shackles Replace 3-1/4" Shackles On Boat Trailer?

Question:

What if your hangers are the same measurements from the bottom of the frame? What size shackle should I use. The original shackles are 3 1/4inch and I have 3 1/2inch shackles now. Will they work?

Since your hangers are the same size you will just want to match the new shackles to your original shackles as that is how the suspension was setup from the manufacturer.

With that said since there is only a 1/4" difference between the original3-1/4" shackles and the new 3-1/2" shackles like the # TRSL350 you purchased you won't have any issues.

I included a video of the # TRSL350 for you to take a look at.
