Boat Trailer Bottoms Out Using Leaf Springs for 6,000 Pound Axles
Question:
I replaced the springs on my boat trailer with 4-leaf Double-eye Spring For 6,000-lb Trailer Axles . same ones thst were on it but I need more lift/clearance once weight is put on it. The u dont seem to hold the weight. The u bolts rest on the frame. Trailer GVWR is 12,600 lbs. So Im debating between the 6 leaf double eye leaf springs for 6000 or 7000 lb axle. Leaning towards the 6000 lb 6 leaf double eye ones since D mesurment is the highest. What would you recommend?

It sounds like your current suspension set up is underrated for the application. But not to worry because we can get you set up. The springs for 7K axles, # e64SR, are going to be stronger so they will not sag as much and retain the ride height better. But the trade off is that the ride quality will be stiffer.
The springs for 6K axles and that have 6 leaves, # e94SR, may put you in the same boat as you are now. The weight of the trailer is going to compress the springs, flatten them out, and it won't matter how tall they are. And if the trailer is bottomed out the ride will be jarring for the trailer. It might be time to at least try the 7K axle springs and see if it is to your liking.
Since it is a boat trailer I assume that the rear axle is worse off than the front axle due to most of a boat's weight being at the rear where the motor is. What can make it worse for the rear axle is if the trailer is being towed nose high. Keeping the trailer level will reduce the stress on the rear axle so keep that in mind as well.
