#LIPPERT FLEX AIR PIN BOX UPGRADE#

I did not want to add side stress to the welds holding the plates that the king pin mounts to. I am also told that the pin boxes that have air bags like the Lippert Trailair and Flexair and Reese 5th Airborn do not work very well in conjunction with a tow vehicle that has a rear suspension supplemented with air bags. The new Trailair Flex Air is about 3/16 narrower than the original king pin.

#LIPPERT FLEX AIR PIN BOX UPGRADE#

The Lippert Trailair only controls up and down movement and the Lippert Flexair controls up and down and back and forth and is an upgrade to the Rotoflex and is an option on the Durango Gold. All others will void the warranty, you were told that at the rally by the Lippert reps.ĭon't want to cause an argument but according to both Morryde and Lippert the MORryde pin box and the Lippert Rotoflex pin box are on a par. The Flex Air® Pin Box by CURT® is the perfect solution. Unlike other options this does a really great job. your Jayco Eagle 321RSTS has a Rhino Box pin box installed on it the best way to improve the ride quality is the Curt Flex Air pin box part LC65VR. Lippert also is the only pin box manufacturer that will keep the Lippert frame warranty intact. Curt Flex Air 5th Wheel Pin Box - Lippert Rhino - 21,000 lbs (145) Trailair Rota-Flex 5th Wheel Pin Box - Lippert 1621 or 1621HD - 18,000 lbs. With a Rotoflex pin box which is what is standard on the Durango Gold line it in fact does move up and down and back and forth and is made to control chucking. Don't know what 5th wheels you where looking at Chuck but at the rally yours was the only one with a MORryde pin box on it. One person was was having his replaced after the rally.
