Trailair® Pin Box - Model L05 Mfg Part Number: 35-946203
Can I pull my fifth wheel coach without air in the air spring?
Absolutely!! Every Trailair air ride pin box design comes equipped with mechanical stops that insure the air spring, shock absorber or other components will be properly maintained in the event of an air failure. In the event the coach is pulled without any air, the ride quality will revert to the quality you had with the standard pin box that you replaced.
