Racewill 10" Boat Trailer Bunk Bracket Kit — 4-Pack Galvanized Swivel-Top, Adjustable Height & Corrosion-Resistant

Racewill 4 Pack 10 Inch Boat Trailer Bunk Brackets are a complete galvanized swivel-top mounting kit designed to support and align bunks for boats, pontoons, and personal watercraft.

If you need a durable, adjustable bunk bracket set to replace worn parts or upgrade your trailer, this four-piece Racewill kit delivers the common industry 10" height plus hardware for quick installation. Built from heavy-duty galvanized iron with extended-thread U-bolts and multiple adjustment points, the kit helps you contour bunks to hull shapes and resist corrosion in both freshwater and saltwater environments.

How will these brackets improve bunk alignment and hull support?

The swivel-top design allows the top plate to pivot so bunks can be set flush against angled or flat hull surfaces, reducing pressure points and improving load distribution. Multiple slotted holes enable precise height and tilt adjustments so each bunk can be tuned independently.

• Swivel top for angle alignment and reduced hull stress
• 10" industry-standard height for common trailers
• Slotted holes permit micro-adjustments of tilt and height
• Separate rectangular and trapezoid brackets for stable mounting

Are these brackets durable enough for saltwater use and heavy loads?

Racewill uses heavy-duty galvanized iron that resists rust and corrosion far better than plain steel, making the brackets appropriate for repeated wet launches and extended exposure to marine conditions. The material and build resist bending and deformation under normal loading from boats and PWCs.

• Galvanized finish reduces surface corrosion
• Thick iron construction holds shape under load
• Hardware sized for frequent trailering and launches
• Suitable for pontoons, boats, and jet skis in freshwater or saltwater

What hardware comes with the Racewill 10" bunk bracket kit?

The package is a complete replacement set: four rectangular base brackets, four trapezoid mounting plates, four U-bolts with extended threads, and the necessary nuts and washers for secure attachment. The extended-thread U-bolts accommodate a variety of crossbeam widths so you won't need custom fasteners.

• 4 rectangular base brackets and 4 trapezoid top plates included
• U-bolt dimensions: 1/2" diameter, 3.5" inside width, 4" length
• Full complement of nuts and washers for assembly
• Pre-slotted holes reduce the need for drilling or modification

How easy is installation and adjustment on the trailer?

Installation follows standard trailer bunk replacement steps and uses the supplied U-bolts and hardware, so most mechanically inclined users can complete the swap with basic hand tools. Once mounted, the slotted holes and swivel top let you fine-tune bunk height and angle without removing the brackets.

• Industry-standard bolt locations simplify fitment
• Slotted mounting holes allow on-trailer angle tweaks
• Extended-thread U-bolts accept varied crossbeam widths
• Complete kit reduces trips to the hardware store

Who is this for: boat owners, marina techs, and trailer maintenance DIYers searching for a reliable, corrosion-resistant replacement or upgrade for 10" bunk mounts. If you want a robust swivel-top bracket set that fits common trailers, lets you contour bunks to different hull shapes, and includes all necessary hardware, the Racewill 4 Pack 10 Inch Bunk Brackets are a practical choice.
