Buying Guide
What to consider when choosing a folding trailer tongue kit:
- Tongue size compatibility: Most kits fit 3 x 3 inch or 3 x 4 inch tongues. Measure outside width and height of your tongue before ordering.
- Towing capacity: Match the kit’s rating to the trailer’s GTWR, coupler, and hitch system. Do not exceed the lowest rating among components.
- Fold mechanism and storage impact: Consider how much space the folded tongue occupies and whether the design allows easy access for parked storage or garage clearance.
- Material and corrosion resistance: Look for forged steel or alloy constructions with powder coating or galvanized finishes for outdoor use, especially near saltwater environments.
- Installation simplicity: Bolt-on designs simplify installation, but confirm beam compatibility and whether professional assistance is needed.
- Safety features: Dual locking systems and secure pins reduce the risk of unintended folding or movement during towing and storage.
