This produces a truck that wanders at highway speed, requires constant steering correction, and wears front tires unevenly. Zone's heavy-duty fabricated steel radius arms physically relocate the radius arm mounting positions to restore correct caster geometry at the lifted position. The forged pitman arm corrects the drag link angle to match the corrected track bar angle. These are not supplemental components — they are the engineering solution to the geometry problem that 7 inches of lift creates on this platform.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eCoil bowing and spring seating:\u003c\/strong\u003e Zone's own page explicitly calls out the coil bowing problem that occurs when lift brackets don't correctly reposition the radius arm pivot points. When the radius arm angle shifts under lift, the coil spring load path becomes angled — the spring bows laterally rather than compressing vertically. Bowed springs seat incorrectly, transfer loads unevenly, and can produce clunking at full travel.

The ball joint cams in this kit change the front axle geometry — on trucks with non-selectable hub-locks, this creates binding and grinding in the front axle. The fix is replacing the non-selectable hub-lock with the selectable version (Ford OEM part PC3Z-3B396-A) before or at the time of installation.

If your truck shows a \"Payload\" or \"Load\" readout on the gauge cluster or center display, you likely have Load Scales. The suspension sensors for this system must be remounted after lift installation using ZONF5502.

At 7 inches of lift on a solid-axle heavy-duty truck, half-measures create expensive problems: caster error that wanders at highway speed, coil spring bowing that clunks and wears, drag link angles that produce bump steer. This kit addresses all of those systematically.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe 2024+ hub-lock requirement is the most common installation surprise on this generation Super Duty lift. Zone lists it on the product page because it's a real, documented issue — not a minor edge case. If you have a 2024 or newer Super Duty, confirm your hub-lock type before the installation appointment. A non-selectable hub-lock that isn't swapped before the cams go in creates front axle grinding that requires the truck to come back off the lift for a partial reinstallation.
