Hey Jim. The Dexter Trailer Springs Over-Under Conversion Kit item # K71-384-00, you were looking at, fits 2-3/8" diameter axles which I doubt your 10,000 lbs 5th wheel trailer has. You most likely need the item # K71-385-00, which fits 3" diameter axles.
To confirm you'll just need to measure the diameter of one of your axles. I don't have a database that shows me what size axle you have but I'd be pretty shocked if you have a 2-3/8" diameter one.
Please note that the Over-Under Conversion Kit item # K71-385-00 is sold individually so you'll need one per axle.
What made you want to lift your trailer?

Hey Jim, did you have a chance to measure the diameter of your axles to confirm the right fit for the Over-Under Conversion Kit? I'm curious to know if the kit worked out for you, as it could help others looking to lift their trailers.
