The trailer lift kit options really come down to the axle type and setup. For leaf spring axles, you can either flip the axles with a kit like part # K71-384-00 or part # K71-385-00 or you can raise the hangers/shackles with a kit like part # LC425750. If you go with the hanger/shackle lift kit you'll need one per axle. This kit will provide about a 2" lift.

Actually the leaf spring part #e28SR that you referenced would be a perfect choice. It's 1/4 inch shorter than what you currently have which is right what you want as old springs tend to stretch over time as they flatten out.
