Recommended Air Ride Pin Box For 2007 Keystone Everest 330B

Question:

I need to replace the king pin box on my 2007 Keystone Everest 330B. The original owners had put on one of the early sidewinders. I have a 2015 Ram 3500 mega cab and us the early model BandW Companion hitch that s in to the goose neck. This sidewinder and Companion hitch are not recommended to use together. I would like to go to an air ride pin box but dont know what the original was on the Keystone Everest to match up too. Please let me know what options I have? Thank you

You are correct that the Sidewinder and B&W Companion Hitch are not compatible. To give you the Air Ride Pin box of your 2007 Keystone Everest 330B, I recommend the 5th Airborne Premium Fifth Wheel Air Ride Coupler - Standard 12-1/2" Wide Air Ride Pin Box # 5AB-S500-700 or the 5th Airborne Premium Fifth Wheel Air Ride Coupler - Extended - 12-1/2" Wide Air Ride # 5AB-E510-710. The correct fit will depend on the pin box bolt hole measurements and I've attached an article to help you determine the correct fit.

This 5th Airborne Pin box will reduce longitudinal shock (chucking) by nearly 60% and decrease vertical shock by 44%. It will not give you the same turning clearance, but it will relieve stress on the frame of your trailer and give you a smoother ride.

Other options are the Trailair Air Ride 5th Wheel Pin Box - Lippert 1116 - 21,000 lbs # LC155943 or the # LC158777. These will also minimize the jarring and chucking.
