Question:

I am replacing the leaf springs and the equalizer on my 2018 grand design momentum 350M. I’m also changing out the shackle kit I ordered the 2.25 wet bolt shackle kit and I cannot get them to attach to the LCI road armor trailer equalizer should I buy the larger shackle kit?

So the issue isn't going to be the shackle strap length as getting straps that are less than an inch longer won't make up the difference you are seeing. The issue is that the Road Armor Shock Absorbing Equalizer Kit # LC696740 you have is the wrong size to replace the equalizers on your 2018 Grand Design Momentum 350M. I was able to check with Grand Design and find the equalizers that fit your rig, which are the Equa-Flex:

- Equa-Flex Cushioned Equalizers # LC279688

I added a photo showing the dimensional difference between the Road Armor and Equa-Flex, with the latter being both taller and wider. A 2-1/4" shackle kit like the MORryde # MR46ZR is correct, but you do need to change out the equalizer to make the connections.
