Question:

replacement air bag I have a M15 trail air pin box and need to replace it Due to age it has some deep cracks. I did have a LO5 pin box and it had a much smaller bag then the M15 so part number would be different so was wondering if you could give me the part number.

Your M15 pin box is the Trailair Air Ride 5th Wheel Pin Box # LC179879 and the replacement air bag it is part # LC432404. You may also want the shock # LC177223 which is designed to help keep the air bag from breaking down as you stated was the issue.

The L05 # LC328492 and has same air bag # LC432404. They have used this for all their air ride options for 18K and 21K models.
