We made sure to replace the leaf springs with the same size (26" eye to eye unloaded) per Dexter customer support and per old measurements. We also replaced the equalizer, bolts, and shackles with the Dexter E-Z flex kit(Part #K71-652-00) that was designed to replace the factory Dexter equalizer we had (Original Part #13-104).
Any advice on correcting this?

Also, once the rubber "springs" is the dexter-equalizer get some miles, they'll settle out a little, and you'll gain a tiny bit of eye-to-eye distance.

The shackles are stronger than the spring-hanger, and that part of the spring hanger doesn't add any strength. The new shackles are just meatier. My vote is just leave it. It's already made clearance for itself.

It's the possibility of the shackles hitting the frame hard and ripping the hanger off the frame that concerns me.

I contacted Dexter who made the original springs and they provided me with the measurement of 26" unloaded based on the original part number and axle serial number. The replacement spring we purchased was 26" unloaded so I'm not sure that is the problem.

That's the first thing we did before installing the new springs, they were pretty much identical taking into account some wear on the old ones. The only difference between the old and new spring packs is the stack height and that's just due to having an extra leaf.

The new springs are rated at 3000lb/ea and the axle is rated at 5200lb (Dexter D52). The measurements from center of hanger to center of hanger is 29.5" and the axles measure about 33" apart on center so based on the Dexter sheet below it would be 26" springs.

My thinking is you may have the same rate springs as far as load goes but, since there is an extra leaf, maybe the longer spring flattens out more before (i.e. it is a lower rating by itself than the original long spring) transferring weight to the other springs. This results in a longer/flatter spring when holding the static weight.

In the 3rd picture labeled original. Is this unsprung? It looks like your stabilizers/jack is down in the background. In the other two pictures is the trailer jacked up the same way?

The third picture is unsprung, jacks were down and that side of the trailer was lifted off the ground. The other two pictures are with load on the springs, when completely unloaded (e.g. lifted off the ground) the equalizers sit correctly.
If the springs are too long am I correct in assuming the options are:
1) Replace all 4 springs, u-bolts, and bushings again with what I assume should be 25 1/8" springs
2) Find a shop to move the hangers a bit
We had two issues that we tried to resolve, the first issue is one of the rear leaf springs were worn out so we decided to replace all of them with slightly higher capacity ones (We fulltime and tow at max capacity often). The second issue is our ass-end kept scrapping on slight angles when towing leveled so we got lift blocks + thicker spring packs to give it the extra clearance.
Here is a picture post-install that has some weight applied to the suspension.

1. Contact Dexter. Get them these pictures and see what they say.
2. Find a trailer repair shop, not an RV shop, to give you suggestions. If you decide to move the hanger locations you want to make sure it is a shop that knows what they are doing.
