I would not recommend going all the way up to the 6,000LB Spring # e47SR as this would cause the suspension to not flex properly with the weight on the trailer. We do have the 4,000LB Spring # e57SR which is only 1/8" longer than the 3,500LB Spring # e54SR. This small difference in length will still work on your setup as the shackle bolts allow for a little play. Don't get hung up the 3,500lb and 6,000lb spring are both 4 leaf and the 4,000lb is only 3 leaf as it is a thicker leaf than the lighter spring. Also be sure to replace all the leaf springs at the same time especially since you are changing capacity.
