Boat Trailer Bunk Kits
Boat trailer bunk kits — often called “blocks” by boaties — give your boat secure, stable support during loading, towing, and storage. Manufactured and designed in and for Australian trailers, these marine-grade kits protect your hull from damage while making trailering easier and safer. Roxom supplies durable, easy-to-install bunk kits built for long-term reliability. Pair them with our trailer brackets for a complete setup.

Bunks, also known as blocks, are an essential part of any boat trailer. Unlike rollers, which guide your boat into place, bunk kits provide firm, consistent support along the hull. This reduces stress points, prevents scratches, and keeps your boat stable during towing and storage.
Roxom’s bunk kits are built from marine-grade materials designed to withstand saltwater, UV, and heavy use in tough Australian conditions. They deliver long-lasting reliability and protection, season after season.
Installation is simple, with most kits designed to fit standard trailers. With basic tools, many Aussie boaties complete the upgrade at home, saving time and workshop costs while improving trailer performance.
For a complete setup, pair your bunk kit with a self-centring kit for easier loading, or add a trailer winch for reliable pulling power at the ramp.
