Hey Andre!

You can still use the same hanger positions as long as your leaf springs from your 3.5K axle are the same dimensions as your 5.2K axle. What is the center eye to center eye length of your 3.5K leaf spring without any weight on it?

For tires, you're looking at 4" of head clearance (to account for suspension travel) and 2" of clearance between the sidewall and frame of your trailer. What tire size are you looking to bump up to?

@Andre The closest we have to that is the 25-1/4" Long 4-Leaf Double-Eye Spring # DX45CR which will work as long as you can use longer shackle straps to take up that extra spacing.
