There are plenty of variables to keep an eye on when you’re towing a high-capacity trailer or RV down the open road—tire pressure, your battery charge, weight distribution. One thing you should be confident about is the security of your load’s 5th wheel/kingpin coupling. With the CURT 5th Wheel Kingpin Lock holding everything together back there, you can breathe easy.
This key-operated, dumbbell-style CURT 5th Wheel Trailer Lock easily slips under the kingpin of any 1.875” to 2” lipped coupler for a fitment even the most experienced hauler can be proud of. Crafted from high-strength aluminum, your CURT 5th Wheel Lock is covered by a 1-year limited warranty.
