Question:

Good day, I’m looking for changing my OEM 1621 pin box on my 293SAB couguar for a Trailair Flex air. I own a 2017 Ram 2500 with rear autolevel air suspension. Is it a good choice, or the suspension of the truck combined to the FW one won’t have a good response? Thanks

We have two Flex Air pin boxes that are a confirmed fit for replacing a Lippert 1621 pin box like what you have. We have the part # LC328492 which has an 18k capacity and the part # LC369535 which has a 21k capacity.

This will work well with your 2017 Ram 2500 that has air autoleveling suspension. They would not fight each other or anything.
