Racewill 10" Boat Trailer Bunk Bracket Kit — 4-Pack Galvanized Adjustable Brackets with U-Bolts

Racewill 4 Pack 10 Inch Boat Trailer Bunk Brackets — a complete galvanized, adjustable bunk-mount kit designed to secure and contour to your boat hull for safe trailering.

When replacing worn bunk brackets or building a new trailer setup, you need hardware that resists corrosion, allows precise alignment, and fits standard crossbeams. This Racewill 10" bunk bracket kit includes four rectangular and four trapezoid brackets, heavy-duty U-bolts, and all mounting hardware so you can set bunk height and angle without hunting for extra parts. The components are galvanized for durability in both freshwater and saltwater environments and sized to match common trailer dimensions.

How do these brackets help secure my boat during transport?

The swivel-top design lets the bunk pad follow your hull profile, reducing pressure points and keeping the hull stable while the trailer is in motion. The kit’s robust iron construction and properly sized U-bolts provide a solid connection to the crossbeam.

• Swivel top conforms to angled or flat hull sections for even support.
• Galvanized iron resists bending and deformation under load.
• 4 rectangular and 4 trapezoid brackets for balanced mounting.
• Includes U-bolts sized to common crossbeam widths for secure fastening.

What adjustments can I make for different boats and trailers?

This kit offers height and angle flexibility so you can match the bunk to your boat’s chine or hull contour. Slotted holes and an adjustable top bracket allow quick tuning during installation or routine checks.

• 10" industry-standard height for most trailer applications.
• Slotted mounting holes enable multiple height positions.
• Adjustable swivel top to set precise bunk angle.
• Extended-thread U-bolt accommodates varying crossbeam widths.

Will these brackets hold up in coastal or freshwater conditions?

Yes — the brackets are made from heavy-duty galvanized iron to slow corrosion and stand up to harsh environments. Properly coated fasteners and solid construction prolong service life when used with regular maintenance.

• Galvanized finish protects metal from rust and pitting.
• Heavy-gauge iron resists bending and long-term wear.
• Suitable for both freshwater and saltwater trailer use.
• Replaceable hardware allows renewal without changing brackets.

What’s included and how straightforward is installation?

The kit arrives complete so you won’t need extra parts to mount four bunks. Installation is straightforward with common hand tools; the design uses standard U-bolts and mounting plates that align easily to the trailer crossbeams.

• Complete kit: 4 rectangular brackets, 4 trapezoid brackets, 4 U-bolts, and mounting hardware.
• U-bolt specs: 1/2" diameter, 3.5" wide, 4" long for typical crossbeams.
• Slotted holes reduce drilling and allow quick adjustments in situ.
• Clear layout means one-person installation is possible in most cases.
