10-INCH EXTENDED VERTICAL ADJUSTMENT: Designed specifically for deep-V hulls, offshore center consoles, and taller trailer crossmembers. These boat trailer bunk brackets allow you to raise bunks higher than standard 8-inch brackets to clear axle geometry and provide optimal hull support.

1,000-HOUR SALT SPRAY RESISTANCE: Built for harsh saltwater and freshwater environments. The primary 10-inch brackets feature heavy-duty galvanized steel with premium Dacromet dip-spin coating to prevent corrosion and rust.

SWIVEL TOP FOR PRECISE FITMENT: Includes adjustable swivel top brackets that allow you to dial in the perfect angle for your specific hull shape. Ideal for heavy fiberglass and aluminum boats, ensuring maximum contact and proper tilt adjustment when using standard 2x4 or 2x6 bunk boards.

UNIVERSAL CROSSMEMBER COMPATIBILITY: Engineered to fit the most common boat trailer frames. Using the included U-bolts, this system mounts securely to 3"x3", 2"x3", and 1.5"x3" trailer crossmembers. Perfect for DIY trailer rebuilds, restorations, and hardware upgrades.

COMPLETE 4-PACK INSTALLATION KIT: Everything required for a full replacement is in the box. Includes (4) 10" vertical brackets, (4) swivel top brackets, (4) U-bolts, nuts, screws, and washers. Ready to install out of the box for marine service shops or DIY boat owners.

Upgrade Your Trailer’s Support System The Wellmax 10" Heavy Duty Boat Trailer Bunk Brackets provide the extra clearance and adjustability required for medium to large vessels. Whether you are rebuilding a worn-out trailer or upgrading to support a deep-V hull, this kit delivers superior structural integrity and precise fitment. Maximum Adjustability for Deep-V Hulls Standard 8-inch brackets often lack the travel needed for offshore center consoles and deep-V fishing boats. The extended 10-inch vertical profile allows bunks to be raised higher above the crossmember, compensating for tall trailer frames or complex suspension geometry. The included swivel tops articulate to match the exact deadrise of your hull, ensuring 2x6 bunk boards lay flat for optimal weight distribution. Extreme Saltwater Durability Corrosion is the enemy of trailer hardware. We engineered these brackets with a dual-defense system against the elements. The main galvanized steel bodies receive an additional dacromet coating, while the U-bolts, nuts, and washers feature a Dacromet dip-spin coating. Tested to withstand 1,000 hours of salt spray, this hardware resists seizing, rusting, and degradation in heavy marine environments.
