Question:

Air bag add on suspension- 2019 F150 4WD…with 5th wheel hitch- Have installed RAS leaf spring add on from you - but need more…. Which air bags will bolt on and work? I once read they don’t fit with a 5th wheel hitch… that has a large bracket bolted to the frame- Thanks Gene B

Hey Gene, the good news is the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3611-YHD you have will work just fine any air bags you want to add since the air bags would mount under the frame and the RAS installs to the top of the leaf springs so they wouldn't interfere with each other.

For an air bag kit, the Air Lift LoadLifter 5000 Air Helper Springs - Rear Axle # AL57385 is a great choice, has up to 5K load leveling capacity, and is custom made to work with your 2019 F-150.

Even with the 5th wheel hitch on it that’s bolted to the frame…correct?

Bryce- one other thing please- it’s 9 1/2 inches from frame to axle- I think I need a spacer- do I need 2 inch or 4 inch spacer… I didn’t realize I’d need one Gene

@Gene The two inch spacer should work just fine. Per the instructions, if that distance you measured is If the is between 6.75"- 7.50" then the included spacer is required but you'd still be around 2" short, so the extra 2" spacer would be needed.
