Dexter Over/Under Axle Conversion Kit K71-385-00 for 3 Inch Tube

The Dexter Over/Under Conversion Kit, part number K71-385-00, converts a single trailer axle setup into an over/under (tandem-style) axle arrangement using a 3 inch axle tube. The kit is built around a tie plate that joins the axle components into the over/under configuration, and it ships complete with the hardware needed for the conversion along with a printed instruction sheet that walks through the installation steps.

This kit is intended for trailer owners and fabricators upgrading or reconfiguring a 3 inch tube axle setup rather than replacing a single worn part, so it includes the full set of mounting hardware and the tie plate assembly rather than just one component. Because it is designed specifically for 3 inch tube axles, it is not a universal fit for other tube sizes.
