Before you back your rig down a ramp, you have to decide which trailer problem to solve first. If your boat trailer is rocking on tired wheels or the hull isn't sitting level on the bunks, two very different parts can help: a $50 wheel and tire package or a $35.99 four-piece adjustable swivel bunk bracket kit. Both support boat trailer launching, but they do it from opposite ends of the trailer.
Quick verdict
If the trailer needs rolling support, the Boat Trailer Wheel And Tire Package is the direct fix. If the trailer already rolls fine but the hull needs a more secure, adjustable cradle, the 4Pcs 8" Adjustable Swivel Top Bunk Bracket Kit is the one to buy.

Product notes
Boat Trailer Wheel And Tire Package
This package gives you six wheel-and-tire sets that are aired up and balanced, and they can be purchased separately or together. It's the direct answer when your trailer doesn't roll well and you want ready-to-mount rolling stock. The Demeter branding and part number Dt13 are useful for matching replacements. The trade-off is scope: this is entirely a wheel-and-tire solution, so it won't help if the real problem is the bunks. If your trailer already has solid rolling gear, it solves nothing at the launch.
4Pcs 8" Adjustable Swivel Top Bunk Bracket Kit
This kit comes with four swivel-top brackets plus the U-bolts, spacers, nuts, and screws needed for mounting. It's made for boat trailers and jet ski trailers with crossmember sizes of 1.5" x 3", 2" x 3", or 3" x 3". The hot-dipped galvanized finish and corrosion-resistant design make it suited for ramp use. The swivel top lets the bunk follow the hull's angle instead of forcing a flat contact patch. The catch is that this is bracket hardware, not the bunk boards themselves; you'll be mounting it to your existing bunks or adding your own. If your trailer's crossmembers are within the listed sizes, it gives you a solid, adjustable foundation.
Final choice by use case
- Need rolling support: Go with the Boat Trailer Wheel And Tire Package. It supplies balanced wheel-and-tire sets that can be used one at a time or all together.
- Need hull support: Go with the 4Pcs 8" Adjustable Swivel Top Bunk Bracket Kit. It fits common crossmember sizes and includes the hardware for an adjustable bunk setup.
