While changing the length of shackle straps isn't an ideal way to change the ride height of a trailer. If you were to shorten the shackle straps the trailer would sit slightly taller. This isn't ideal as the leaf spring wouldn't sit level if you made a drastic change. Over under kits are better for changing ride height as you get a more substantial lift and the suspension stays level.

The diameter of your trailer axle will determine the size of the parts that you will need to order. If your axle is 3 inches diameter, the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00, would be a great choice and if your axle is 2-3/8 inch diameter you could use the Over-Under Kit, # K71-384-00. These kits can be installed without welding but the manufacturer strongly recommends having the new spring seat tacked in place on the other side of the trailer axle.

Some refer to this process as "flipping the axles," but since axle has a slight bow to it you can't just flip them and reinstall them under the springs using the same spring seats. You have to install new spring seats on the opposite side of the axle so that it can be moved below the spring.
