Extreme Max 3006.7147 Aluminum Bunk Bracket Kit
The Extreme Max kit includes swivel-top bunk brackets designed to fit 3″ x 3″ trailer crossmembers. All brackets are aluminum with stainless hardware for corrosion resistance. Best for DIY bunk setups that require adjustable angles to cradle a boat precisely. This kit is ideal for small to mid-size aluminum or steel trailers that need a customizable fit. A potential limitation is that the kit assumes standard crossmember sizing; confirm fit on your trailer before purchase.
Folding Trailer Tongue Kit (3×3) with 5,000 LBS Capacity
This kit is designed for 3×3 inch outer square trailer tongues and offers a 5,000 lbs load capacity. It is built from AISI 1045 steel with a silver coating to resist corrosion. Best for trailers needing space-saving folds and for users who require a strong, steel hinge for frequent folding. Limitations include compatibility notes: not for aluminum frames and proper mounting to steel frames only.
Ultimate Aluminum and Stainless Steel Bracket Kit – 10 Inch
All aluminum and stainless steel parts make this kit well suited for saltwater environments or where corrosion protection is essential. It fits a 3″ x 3″ crossmember with U-bolts sized 1/2″ x 3″ x 4 5/16″. Height-adjustable 2×2 10-inch aluminum pole enables flexible bunk placement. Best for users who prioritize full aluminum construction and coastal use. A caution: ensure crossmember compatibility and correct lug spacing before installation.
Partsam 1 Pair Boat Trailer Guides Kit
Guides improve loading accuracy and night visibility, featuring top lights and a galvanized steel frame. The kit helps align a boat on the trailer, reducing hull contact during loading and unloading. Best for anglers and skippers who back trailers at night or in dim conditions. The main caveat is that the guide poles are galvanized steel, not aluminum, so rust resistance relies on protective coatings and rinsing after exposure.
8″ Aluminum L-Type Bunk Bracket Kit
This kit uses all aluminum and stainless parts with 1/2″ diameter U-bolts and standard 3″ x 3″ crossmember fit. The L-Type bunk brackets are 8 inches tall, designed for vertical bunk boards, offering a sturdy setup for compact spaces. Best for boats that require vertical bunk support and saltwater durability. A limitation: crossmember compatibility should be checked for exact fit on your trailer.
Ultimate Aluminum and Stainless Steel Bracket Kit – 14 Inch
All aluminum and stainless steel parts provide corrosion protection for saltwater use. Includes U-bolts fitting a 3″ x 3″ cross member. The 14-inch pole length offers a higher bunk position for larger boats or taller trailers. Best for owners needing higher bunk clearance and strong, corrosion-resistant hardware. Caution: verify the mounting height and crossmember spacing matches your trailer’s design.
Boat Trailer Guides 20″ Aluminium Alloy Kit
Longer 20-inch aluminum guide poles offer extended guidance for wide boats and taller trailers. The kit uses 316 stainless steel throughout critical mounting hardware and top-grade rubber crash pads to limit hull damage. Best for boat trailers that require extra guidance length and strong corrosion resistance. A potential drawback is the heavier overall weight from extended poles.
