Replacing leaf springs or installing helper springs

I also replaced mine. It had 3000 lb. springs with 4 leafs went to 3300 lb. 5 leafs on 6000 lb. Axels and are still holding up well after three years. I got my springs from e-trailer.com. Yea I know they are China springs but they are holding up pretty well. At the time I could not afford the usa springs. I jacked the whole thing in the air and did all in a weekend with the wet bolt kit. It rides so much better.
