Question:
I have a boat trailer for a 18 ft fiberglass boat the bare weight of the hull is around 850 lbs. Buy the time I get the motor on it gas tanks batterys and a few other things I figure the boat will weigh about1600 to 1900 so I want heavy duty springs so I was looking at these springs but would these stiffen up the ride over stock springs or would this be a problem thanks

Expert Reply:
The leaf springs should be rated to match the axle on the trailer. Spring # e27SR is rated for 2,250 pounds per spring so it fits 4,500 pound axles. These springs would be overkill for a boat weighing up to 1,900 pounds and it would be a very stiff and jarring ride for your boat.
Your trailer axle may have a capacity listed on it somewhere and if not then there should be some capacity information on a placard or sticker near the front of the trailer somewhere. Whatever the gross capacity of the trailer/axle ends up being is what you will want the combined capacity of the springs to be. A little higher is fine but never lower.
So if you had a 2,000 pound axle you could use # e84SR, # e77SR, or # SP-113275 depending on the length needed. The next step up from there is # e66SR rated for 2,500 pound axles.
Beyond that the next capacity is for 3,500 pound axles and even those would be too stiff for a 1900 pound boat.
