This decision is still open. 3 options are being compared, nothing has been ordered, and no manufacturer has been committed to. Where one option is marked as currently leaning, that's a preference at this stage — not a decision.

1 in adjustable rear sway bar

Current preference — no decision made

Part number: 7788

Why this option

Adjustable so roll stiffness can be tuned once the Airstream is actually behind the truck, rather than committed to a fixed rate on paper. Reduces body roll under trailer load without touching ride height or spring rate.

Roadmaster

Researching

Why this option

Addresses trailer-induced sway from a different direction, adding progressive spring assistance rather than roll stiffness.

Where it currently stands

Overlaps with what the Timbren kit is already doing for load support. Adding roll stiffness and progressive springing to the same axle risks over-correcting the rear.

What it actually cost

Ford (OEM)

Researching

Why this option

No cost, no added weight, no change to a suspension Ford already validated for this truck's tow rating.

Where it currently stands

Body roll under a 6,500 lb trailer is the specific complaint being solved. Leaving it stock means accepting it.
