Recommended Trailair Air Ride Pin Box for 1621 Pin Box on Trailer

Question:

I want to purchase an air-ride LIPP1621. You show a model on your site of 21,000lbs but mine states LIPP1621 Pinbox Rating 15,500lbs. Is this the same part. Thanks.

The Trailair Air Ride 5th Wheel Pin Box # LC158778 referenced in your question is an upgraded pin box that is designed to replace the Lippert 1621 pin box like what you have. This will work great on your trailer and provide you with much improved handling and a nice, cushioned ride.

This does indeed have a higher 21,000 pound weight capacity when compared to the standard pin box that it is replacing. With this in mind, you will still need to follow the trailer's original weight rating even though the pin box can now handle a bit more. A trailer will always be limited by its weakest component, so even if the pin box is rated higher, another component such as the suspension or axle will still limit its capacity to the original number.

I have attached a short video demonstration on this product that you can also check out.
