It can take a lot of time to build or repair a heavy-duty trailer, which is why our team at The Trailer Parts Outlet has created these 15K trailer axle kits. Each Midnight Series package includes all the parts you need, such as axles, springs, U-bolts, and tire and wheel assemblies (TWAs). By ordering one bundle from us, you can cut down on the time it takes to source all your parts, giving you more time to work on your trailer. The TWAs feature a black mod OEM finish, so when you’re ready to put them on the axle, they’ll add that perfect touch to the new or restored trailer. Order yours now!
