Yes, you can use the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00, for 3" diameter axles or the Over-Under Kit, # K71-384-00, for 2-3/8" diameter axles on your tandem axle trailer. These kits are applicable only to trailers with leaf springs and should be installed only if the suspension overall is in good working order. One kit is required per axle.

Typically, 2-3/8 inch axle diameter is a 3500 lb rating; and 3 inch axle diameter is typically a 6000 to 7200 lb weight rating. You will want to confirm your axle diameter before ordering.

These kits are bolt-on, but the manufacturer does strongly recommend tack welding the new spring seats in place to prevent axle slippage.

I have also included a photo showing how the various parts are to be assembled.

Bear in mind that lifting your trailer will result in changes to its geometry and balance; tongue weight could change and the potentially top-heavy stance could require a weight distribution system with sway control to restore handling. I have included a link to an article on weight distribution and sway control.
