KJE 8" Swivel-Top Bunk Brackets 4-Pack — Heavy-Duty Galvanized Steel, Fits 2"x3" & 3"x3" Crossmembers

KJE 4Pack 8" swivel-top bunk brackets are heavy-duty, galvanized steel mounts that secure and align boat bunks on 2"x3" or 3"x3" trailer crossmembers while resisting corrosion from marine exposure.

These bunk brackets are engineered for trailer owners who need reliable, adjustable support for a range of boat hull shapes. Each kit includes four 8" swivel-top brackets, corrosion-resistant galvanization with a protective black spray finish, and the hardware required for installation. Built from high-strength steel, the brackets clamp to common 2"x3" and 3"x3" crossmembers and let the top plate rotate so you can fine-tune the bunk angle for safer launching, loading, and transport.

How do these brackets improve boat support during transport?

The swivel-top design lets you align bunks precisely to the hull contours, reducing pressure points and shifting during transit. Heavy-gauge steel construction maintains structural integrity under load so your boat stays stable on ramps and roads.

• 8" top plate swivels to match hull angles
• High-strength steel resists bending under load
• Galvanized finish reduces rusting in salty or wet conditions
• Compatible with common trailer crossmember sizes

Will these fit my trailer crossmembers and bunk boards?

Yes — the brackets are sized to clamp securely to 2"x3" and 3"x3" rectangular crossmembers used on many trailer frames. The U-bolts and included hardware accommodate typical bunk board thicknesses and can be tightened with basic tools.

• Designed for 2"x3" and 3"x3" trailer crossmembers
• Includes U-bolts and nuts for secure clamping
• Top plate accepts standard bunk board mounting
• Works with carpeted or padded bunk setups

How durable and corrosion-resistant are these brackets?

The brackets use galvanization plus a black spray coating for a two-tier protective layer that lasts longer than simple paint. This finish minimizes surface wear and slows oxidization, making them a good fit for freshwater and occasional saltwater use when rinsed and maintained.

• Galvanized base layer for long-term rust resistance
• Black spray coating adds abrasion protection
• High-strength steel core for load-bearing durability
• Simple maintenance extends service life (rinse and inspect)

How easy is installation and what hardware is included?

Installation is straightforward: position the bracket on the crossmember, place the bunk board on the swivel top, then tighten the U-bolts and fasteners provided. All necessary mounting hardware comes in the kit, so you won’t need specialty parts beyond common wrenches.

• Complete kit with U-bolts, nuts, and mounting bolts
• Basic hand tools (wrench) required for assembly
• Swivel top allows angle adjustments without removing hardware
• Clearances fit standard bunk board thicknesses

Who is this for: Boat owners, DIY trailer maintainers, and small marinas who need a reliable, adjustable bunk mounting solution for everyday towing and launching. If you have a trailer with 2"x3" or 3"x3" crossmembers and want a corrosion-resistant bracket that lets you fine-tune bunk angles, this KJE 4-pack is a practical upgrade offering durability, easy installation, and improved hull support without specialized tools or fabrication.
