Replacement Air-Ride Pin Box for 2012 Keystone Alpine 5th Wheel

Question:

2012 Keystone Alpine, it says Lippert 1621 does it matter if it is a HD or not? I have a long bed on my 2006 Ford F-350. Thanks How much do I torche the bolts down if I do this myself?

According to Ultra-Fab, the Trailair Air Ride Pin Box, part # LC158778 is compatible with either the Lippert 1621 or 1621HD pin box. The Trailair does an excellent job of absorbing road shock with its inflatable air bag, but the Trailair Tri-Glide # UF35-946229 takes it a step further by adding an articulating lower jaw that helps absorb the chucking (fore and aft jarring) that can make towing a chore.

The # LC155943 TrailAir pin box you referenced is compatible with a Lippert 1116 or 0115 pin box only, and would not work with your Lippert 1621.
