Buyer’s Guide: What to Consider

Choosing the right folding tongue kit involves a few key factors. Here’s what to consider to ensure you get a safe, compatible solution for your boat trailer.

• Towing Capacity: Match the hinge's weight rating to your trailer's gross vehicle weight rating (GVWR). Overloading can be dangerous.
• Tube Size Compatibility: Measure your trailer tongue's beam dimensions (e.g., 3×3 inches) to ensure the kit fits properly.
• Installation Method: Bolt-on kits are easier for DIY, while welded options may offer more strength but require professional help.
• Corrosion Resistance: For boat trailers, look for galvanized or powder-coated finishes to withstand moisture and saltwater.
• Space Savings: Consider how much the folding tongue reduces storage length. Swing-away designs typically offer the most reduction.
