If you can get me the length of your current springs (one of the good ones) and the axle capacity I can see if we have one that will fit and also one that would have the amount of leaves you want. If we don't have a 6 leaf spring we do have lift kits like the # RR23QX which will give you a lift of up to 2-1/4 inches.

Best way for your situation would be to jack the trailer frame up into the so that the wheels are off the ground and there is no load on the suspension and then measure from spring eye center to spring eye center. Then for capacity you can look on the axle and there should be a sticker with that info listed. Or you can also measure the axle diameter and that will work too. Typical Axle Diameters Based on Axle Capacity - 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter - 3,500-lb Axles: 2-3/8 inch diameter - 6,000-lb - 7,200-lb Axles: 3 inch diameter - 8,000-lb Axles: 3-1/2 inch diameter - 9,000-lb Axles: 4 inch diameter - 10,000-lb Or more axles: 5 inch diameter

The closest option we have would be the part # e64SR which is for a 7,000 lb axle, has 6 leaves, and is 24-7/8 inches in length. It looks like yours currently are pretty flat from being worn out which adds length when you go to measure them so the length should work fine as long as the slightly lower weight capacity of the springs would be okay.
