Why selected: This kit centers the boat during docking, reducing hull contact on uneven ramps and rough roads. The design supports versatile installation with U-bolts that can mount straight or crossed, offering adaptable fit on various trailer configurations.
Limitations: Installation requires attaching frames to trailer rails; ensure your frame width matches the guide poles for proper centering.

Best for: Boat owners needing a robust, corrosion-resistant setup with a refined design for centered loading on high-beam, box, or C-channel trailers. The kit includes 18-1/4 x 16-3/4 inch guide poles with 13-inch adjustable width.

Buying Guide
What should I look for when choosing boat trailer bunks?
- Trailer compatibility: Verify frame width, beam type (high beam, box, or C-channel), and whether the bunk guides require straight or crossed mounting.
- Board material and carpet: Marine-grade carpet protects hull surfaces; thicker carpet offers better hull protection and longer service life.
- Board dimensions: Longer bunks offer broader hull support; shorter boards can be easier to install on smaller trailers. Check if the boards are 2×4 or 2×6 and the exact length.
- Mounting hardware: Durable, rust-resistant brackets and U-bolts extend life in saltwater or rough road conditions. Ensure compatibility with your trailer crossmember size.
- Adjustability: Some systems offer adjustable heights or angling; these features help accommodate a range of boats and ramps.
- Installation complexity: Consider whether you prefer a straightforward bolt-on kit or a more involved install that requires frame modification.
