Single axle trailer leaf springs

Hello!
I own a boat MasterCraft Sport Star with OEM single axle trailer. Iím plan to change the leaf springs for my trailer.
Anyone can help me to choose applicable for me leaf springs. I want to buy on this site http://mcpartsdepot.com/collections/mastercraft-trailer


Thanks all

I don't blame you for changing the leaf springs, I had one break on my '93 Prostar trailer on the road! Not fun.

No need to overpay and order from the mcpartsdepot.com website. There is nothing special about the leaf springs. Simply measure the distance from eye to eye on the spring and order ones with the proper weight rating.

You may want to contact thatsmrmastercraft (Peter) on here, he sells trailer parts and is great to deal with.

Otherwise the first place I thought of, but I'm sure there are plenty others that offer the same thing:

When I bought the trailer springs were not OEM, and once they broke far from home on road, and now i dont want to deal with handmade springs and would like to get OEM springs.

Thanks a lot for the links, very useful information.
Can you advise me what capacity to choose - 3500-lb or 4800-lb or 6000-lb?

The best way would be to determine the load rating of your axle. There may be a sticker on the trailer tongue that lists the specs. If not, I'd guess you have a 3500 lb axle. So, the capacity of both springs need to add up to the capacity of the axle. For a 3500 lb axle, each spring needs a capacity of 1750 lb or more. You don't want to be way over or the trailer will ride very stiff.

Another way to determine this may be to check your tire weight ratings. If you have load range C tires, they are only rated to around 1750lb each, so you need a spring with a rating at least that on each side.

Many of us on here have used these:

I took it to a really good trailer shop to have them do it in a pinch and their standard 3500 lb springs did not fit. I ordered from northern and they fit great.
