1,500 lb Slipper Springs or 1,000 lb Slipper Springs for a Trailer


My Jon boat trailer currently has 2-Leaf Slipper Spring for 1000# axle but they are rusted out. I was thinking of going up to the same spring in the 3 leaf version because the current ones seem rather wimpy and soft and the boat almost hits the fenders on a big bump. Is there a real problem with using a 3 leaf replacement for a 2 leaf spring or is this ill advised given that I only have a 1000# axle?

The best way to pick out a slipper spring replacement for a trailer is to base it off of the weight capacity for the trailer and then the dimension of the spring getting replaced.

Sounds like you are considering going with the # SP-178275 over the # SP-177275 for your trailer. Both of these springs share the same dimensions, but since your old springs seem to be too soft it would seem like the # SP-178275 would be a better choice.

You should note that going with a higher rated spring won't give you a higher trailer capacity since that is only one component of the setup. Since your axles are only rated for 1,000 lbs you would at least be limited to that.
