Air Ride Helper Spring Option for 2011 Ford F150 FX2

We do indeed have an air spring application that will fit your truck. I checked with my representative at Air Lift, and was told that unless your 2011 F150 FX2 was lowered, their # AL57228 would be a fit.

You might also be interested in a compressor system like part # AL25592. A compressor system would allow you to add or remove air from the system with a press of a button from the comfort of your truck cab.

All this being said, if your main reason for the air spring system was to counteract the sag in your rear suspension when a trailer is hitched, using a weight distribution system would work better. A weight distribution system will use leverage to distribute a portion of the trailer tongue weight to the front vehicle axle, thus making the ride height even (or nearly so) between the front and rear of the vehicle. This can lead to better handling, better braking performance and improved steering response because the front suspension isn't being unsprung by the trailer tongue weight being applied at the rear.

To choose a weight distribution system, you'll need to first determine the fully loaded and ready to tow tongue weight of your trailer. To that figure, add the weight of any gear stowed in the cargo area of the SUV or truck bed behind the rear axle. I've linked to an FAQ article that explains how to do this. These combined figures comprise the Total Tongue Weight (TTW) of your set-up. The TTW of your trailer should fall as close as possible to the middle of the effective range of the weight distribution system you choose.

If this sounds like an option you might be interested in, I'd be happy to make some recommendations if you would reply with the fully loaded tongue weight of your trailer.
