With the coilovers to dampen the trailer springs it should be okay weight-wise. Trailer springs short and made to be run loaded, so they may be a little bouncy. They may seem too stiff, but I'd try them before removing a leaf. You need to know how much dampening the coilovers do per inch of travel so you can set them up right. They might not travel far enough to do the job. Even though they are adjustable, you may wish to build an adjustable top mount too. Depends on what kind of driving you will be doing. They may like a little tension with the suspension all the way down. (tires hanging all the way down). See, if you have (for example) 4 inches of axle travel, and you need to move the shocks 6 inches to get them to stiffen....they won't. You're breaking new ground, so be ready to adjust it when it's running again.
Free is a good price.
