Default Raising trailer for taller tires

My trailer is a 99 Hoss, triple, with 3500 axles
After doing brakes and bearings, which honestly were damn good for not being touched in 15 years!
I noticed my bushings were shot!
Also needing to find to odd sized leaf springs, 4 leaf with 23.5" eyes No one has anything close.
But my main question is, what can be done to raise the setup to accommodate taller (15") tires!
Currently running 195 14s! yes they are C rated, but want something better!

I have read a couple places to just install triangle equalizers! Currently have straight eq's with a 5.5 center.
I have found a set of 5.5" triangle with a 3.5" height.
Would it be that easy?

Or do I need to change more?

Without re-welding everything, my next best option is to pull the boat off and make spaces under all the bunks to raise the boat up. Then I can raise the fender after.

I'd be real careful about changing anything related to suspension geometry without some truly professional advice. Raising the boat up by adding spacers would probably be easier. Just remember that depending on how your bunks are matched to the hull / lifting strakes, you may have to move out a bit to retain the same positioning.

Suspension geometry on a trailer is a joke. You'll be lucky if the axles are straight from the factory. I've done a couple by moving the axle from on top of the spring to the bottom.

I looked at this as well last year to be able to get 15" load range E tires on my Phoenix trailer. Currently running 14" load range C tires by the way. My local trialled service center strongly advised against changing the geometry by installing taller equalizers. The outcome would be very poor handling and increase sway.

Other may have more informed information, but this is what I have to pass on.

Thanks, that is what I was looking for! real world experience and not two people showing it online!
It does, did, not sound possible to me and keep things level.
as for the bunks, being a cat and the placement of the current bunks I feel there is enough room to raise an inch.
Yes I know that will push things out, but I have more then enough room. now if I go 3 inches that might be a different story
As for swapping spring seats, that would but me at over a 4 inch rise and I do not want to go that high

so once I find a replacement set of springs this thing will go back together and the fall will be time to lift the boat off the trailer!

Have you considered hydraulics?
