Hey Zachary, thanks for reaching out. I can help with that.

Can you tell me the length of the shackles currently on your trailer? They are measured from center hole to center hole. They are likely either 2-1/4" long or 3-1/8" long but please confirm. Also let me know what kind of trailer you have and how many axles it has. Shoot me that info when you get a chance and I'm happy to make a recommendation.

Are you needing a new equalizer too?

Hi Jesse it’s a boat trailer tandem axle. I measure 2 1/2 form center to center on the shackle. And I also need the equalizer as well. And that one should be 5 1/4 from center to center on the outside of the equalizer. I have a hand written diagram with the measurements as well

@ZacharyH Gotcha! For the shackle kit, the MORryde Suspension Upgrade Kit for Tandem Axle Trailers # MR46ZR is what I recommend. It comes with 1/2" thick HD shackles, wet bolts and bronze bushings. For the equalizer, I recommend part # K71-654-00 for an upgraded cushioned equalizer. Or part # TREQ104 for a standard equalizer.

@JesseM my equalizer is straight.
