Is the Trailair Flex Air Pin Box LC328492 The Same Length As a Lippert 1621

Question:

Is the Flex Air pin box 328492 that replaces the Lippert 1621 pin box the same overall length or does it extend past the front cap ? My garage door is within 2inch of the point of the front cap on my Momentum 351M Thank You,

The Trailair Flex Air 5th Wheel Pin Box part # LC328492 will have the same basic dimensions as the Lippert 1621 Pin Box that it is replacing but the shock absorber sticks out further. The distance from the center of the king pin to tip of the shock absorber is about 12".

If the Trailair Flex Air 5th Wheel Pin Box won't work we have the 5th Airborne Premium Fifth Wheel Air Ride Coupler part # 5AB-E1621-610 which has the same features as the above without the extended shock absorber so this will be a better choice for you. The shock absorber on this unit is located inside along with the airbag.
