Question:

My Trailair pin box has almost 60k towing miles on it and the bushings and shaft shown in the picture are worn out and need to be replaced. The Lippert SKU for the bushings is 156144 but i cant find the SKU for the 1.5inch shaft. Do you stock these parts or are you able to get these parts from Lippert. If so, could you please reply with your part #s and price. Thank You

Expert Reply:

The reason that you cannot find the replacement shaft is because Lippert does not offer this separately. If the shaft is worn or damaged then it is time to replace the pin box. There are only very minimal replacement parts for these pin boxes (valve part # LC156740, shock part # LC177223, airbag part # LC432404) and this is intentional to discourage home repairs on such a critical component.

That said, this might be a good to time to upgrade from the Trailair Air Ride 5th Wheel Pin Box to a Trailair Flex Air 5th Wheel Pin Box like part # LC328492 which has a pivoting head that works to better decrease chucking and jarring even more so than the airbag and shock. This is a pretty big upgrade so it is worth the extra cost. If you can let me know what model number (1621 Etc.) you have I can make sure you get the correct replacement.
